BOAs and SOAs are single-pass, traveling-wave amplifiers that perform well with both monochromatic and multi-wavelength signals. Since BOAs only amplify one state of polarization, they are best suited for applications where the input polarization of the light is known. For applications where the input polarization is unknown or fluctuates, SOAs are required. However, the gain, noise, bandwidth, and saturation power specifications of a BOA are superior to that of a SOA because of the design features that make the SOA polarization insensitive.

Our SOA1117S and BOA1004P optical amplifiers are also available in the S7FC1013S and S9FC1004P benchtop optical amplifiers, respectively.

Thorlabs offers fiber-coupled BOAs and SOAs that exhibit low coupling losses, as well as free-space BOAs as a chip on submount (C) or chip on heatsink (H). Losses typically range from 1.5 to 2.5 dB for the fiber-to-chip and chip-to-fiber coupling (each). This affects the total gain, noise figure (NF), and saturation power (P_sat). While the gain produced by the amplifier exceeds that of the losses, these losses remain an important factor in determining the device's performance. For instance, a 1 dB drop in input coupling efficiency increases the noise figure by 1 dB. Alternatively, a 1 dB drop in output coupling decreases the saturation power by 1 dB.

Driver Option
The CLD1015 butterfly LD/TEC controller is one possible controller for these the butterfly-packaged amplifiers. The LD/TEC controller and mount combination offers full control via a touch screen. When operating the optical amplifiers on this page with the CLD1015, the orientation for type 1 pin configurations should be used.

Center Wavelength Note
The center wavelength (CWL) of the ASE spectrum in broadband semiconductor devices such as optical amplifiers may show variation between lots. Please refer to the Specs tab for the CWL tolerances of each particular model. For applications in which a specific ASE center wavelength is a critical concern, please contact Tech Support for information on the CWL of currently available lots.

Comparison of a SOA to a standard Fabry-Perot Laser Diode

Booster optical amplifiers (BOAs) and semiconductor optical amplifiers (SOAs) are single-pass, traveling-wave amplifiers that perform well with both monochromatic and multi-wavelength signals. Since BOAs only amplify one state of polarization, they are best suited for applications where the input polarization of the light is known. For applications where the input polarization is unknown or fluctuates, SOAs are required. However, the gain, noise, bandwidth, and saturation power specifications of a BOA are superior to that of a SOA because of the design features that make the SOA polarization insensitive.

BOAs and SOAs are similar in design to Fabry-Perot Laser Diodes, the difference being that Fabry-Perot laser diodes have reflective coatings on both end faces of the semiconductor chip. The optical feedback from the reflective end faces establishes a cavity in which lasing can occur. SOAs and BOAs have an anti-reflection (AR) coating on both end faces of the semiconductor chip. The AR coatings limit the optical feedback into the chip so that lasing does not occur.

As is typical for all amplifiers, BOAs/SOAs operate in two regimes: a linear, flat, constant gain regime and a non-linear, saturated output regime. When used to amplify a modulated signal, the linear regime is typically used to eliminate pattern-dependent distortion, multi-channel cross-talk, and transient response issues common to EDFAs. The non-linear regime is used to take advantage of the highly non-linear attributes of the semiconductor gain medium (cross-gain modulation, cross phase modulation) to perform wavelength conversion, optical 3R regeneration, header recognition, and other high-speed optical signal processing functions.

For a continuous wave input signal, the amount of power that can be produced by the amplifier is determined by the saturation output power (P_sat) parameter. P_sat is defined as the output power at which the small-signal gain has been compressed by 3 dB. The maximum amount of CW power that can be extracted is approximately 3 dB higher than the saturation power.

Dear Sir or Madam, I could not find following information in the spec sheet: (1) FC/APC connector key is aligned to slow or fast axis? (2) Amplification is really aligned to fast axis as commented in Feedback section? (slow axis typically is better suited for PM stability and wide spread standard) (3) What is the absorption value of the BOA when short circuit? Preferably high, in range 40...50dB? Thank you very much

YLohia (posted 2021-03-12 04:47:46.0)

Hello, thank you for contacting Thorlabs. (1) It is aligned to the slow-axis (2) It is aligned to the slow axis, not the fast axis (3) Unfortunately, we don’t have spec of absorption value for BOA1004P when no current is applied. If you have a key requirement for it, the BOA1004PXS would be more suitable since it has an isolation spec of > 40 dB when no current is applied.

Hi, I have a question for SOA graphs. I'm just wondering that the reason why the SOA 1013S and SOA1117S has different tendency according to Gain vs wavelength. The graph of SOA 1013S in appendix tends to be decreased while that of SOA 1117S tends to be increased. I'm waiting for your reply. Thank you.

YLohia (posted 2018-10-19 12:08:41.0)

Hello, thank you for contacting Thorlabs. The reason is that the peak of the ASE for SOA1013S happens at ~1500-1510 and that of the SOA1117S is at ~1550nm. Thus, based on the 1528-1562nm (C-band) region shown in the plots in question, the plot decreases for SOA1013S and increases for SOA1117S. Both of SOA1013S and SOA1117S are for C-band applications and we only test gain across this window. For the SOA1013S, which is marketed as a linear device (due to its high saturation power), we intentionally set peak gain wavelength at ~1500nm to obtain higher saturation power in the C-band. The saturation power tends to be higher on the longer wavelength side of the peak.

kyeongpyo.lee (posted 2018-09-19 05:10:10.58)

I was testing the small signal gain by using BOA1007H, and I found that whatever the input power is (i.e. -50dBm or -20dBm) its amplified output is fixed at about -13dBm for 200mA current supply. I cannot understand this situation. Is it possible to do so?

YLohia (posted 2018-09-25 10:05:02.0)

Hello, thank you for contacting Thorlabs. Please note that the performance of the BOA is highly dependent on its junction temperature and, thus, the unit should be used under properly temperature controlled environments. The BOA1007H will already start to produce gain (around 10-20dB) even with a 200mA drive current at 1550nm. It is quite likely that your input coupling efficiency to the BOA is not high enough, which would imply that the chip is not receiving enough light to amplify. The measured power then will be the BOA's ASE power itself, which can be around 5mW at 500-600mA of drive current. This is the fixed output you are seeing at these low input power levels. If you find that the power of your signal of interest is not high enough compared to the ASE, you may want to use spectral filters to attenuate the ASE signal. FBH1550-12 or FB1550-12 would be good choices to look into for the 1550nm center wavelength.

Response from Bweh at Thorlabs USA: Yes these can amplify a 10Gb/s or 20Gb/s modulated optical input as well as cw. In fact, the original application of the SOA design was a telecom alternative to EDFAs. However, the peak power levels will be limited to the cw saturation power.

jjurado (posted 2011-05-18 13:08:00.0)

Response from Javier at Thorlabs to jikim: Thank you very much for contacting us. You are correct, since SOA is polarization dependent, the gain at fix current and wavelength will vary if the polarization state of the input changes. So, the maximum and minimum gain curves just describe the window of gain changes vs. polarization state. The difference between the max. and min, gain values correspond, then, to the polarization dependent gain (PDG) spec in the Specs tab.

A response from Adam at Thorlabs to Sema: Previously, Covega has produced BOAs at this range, 1060nm. Thorlabs Quantum Electronics is planning on releasing a similar BOA in the next couple months. Will this work? At this time, there are no plans for the release of a SOA at this wavelength range, but if we can get more information about your application, I can suggest this as a new product idea. That being said, do you need a BOA or a SOA? Previously, most of our customer at this wavelength were either (1) making a laser for OCT or (2) amplifying 1064nm seed laser-- both of which a BOA is better suited than an SOA. I will email you to get more information for your application so we can suggest the most suitable product.
