High-Speed Optical Shutter/Switch
The SOA1013SXS and BOA1004PXS Optical Switches are designed specifically for applications requiring an optical shutter with operation around 1550 nm. Both the polarization-independent SOA1013SXS and the polarization-dependent BOA1004PXS provide an extinction ratio greater than 60 dB. The devices are based on our semiconductor amplifier platform consisting of a highly efficient InP/InGaAsP Multiple Quantum Well (MQW) layer structures grown on an InP wafer and processed into a proven and reliable ridge waveguide. The device can operate as a lossless, high-speed, optical isolation switch, a full-range variable optical attenuator (VOA), or an optical shutter for protection of delicate optical equipment.
The SOA1013SXS polarization-independent switch features the right combination of low polarization sensitivity, wide optical bandwidth, and high extinction ratio for an optical isolation switch. Using the gain/absorption properties of the MQW structure, the device can function as an optical blocking shutter with no reflections. In addition, the switch is also designed to support the highest gain and signal levels, allowing it to function reliably at signal levels of 15 dBm and above. The SOA1013SXS is also ideal for applications where the input signal polarization is unknown or fluctuates. The device comes in an industry-standard 14-pin butterfly package with single mode fiber (SMF) pigtails that are terminated with FC/APC connectors.
The BOA1004PXS polarization-dependent switch offers the user full control of the power level making it ideal for high-power laser pulse generation systems like cavity ring-down sensors and LIDAR systems. The device comes in an industry-standard 14-pin butterfly package with polarization-maintaining fiber (PMF) pigtails that are terminated with FC/APC connectors and key aligned to the slow axis. The BOAs can be customized upon request to have isolators on the input, output, or both. Please contact Tech Support for help customizing a device for your application.
