Si Fiber-Coupled Amplified Photodetectors
Menlo Systems' high-sensitivity Silicon (Si) PIN photodetectors are easy-to-use photodetectors with an integrated high-gain, low-noise RF (FPD310-FC-VIS) or transimpedance (FPD510-FC-VIS and FPD610-FC-VIS) amplifier.
The FPD310-FC-VIS is optimized for high gain, high bandwidths, extremely short rise times, and high signal-to-noise ratio. The gain can be switched between two settings, which allows optimal performance for many applications. The 3 dB bandwidth of this AC-coupled device is 5 - 1000 MHz.
The FPD510-FC-VIS and FPD610-FC-VIS photodetectors are optimized for maximum signal-to-noise-ratio for detection of low-level optical beat signals and pulse shapes at frequencies up to 250 MHz and 600 MHz, respectively. Both detectors have a fixed gain. The FPD510-FC-VIS has a rise time of 2 ns, while the FPD610-FC-VIS has a 1 ns rise time. The 3 dB bandwidth of these DC-coupled devices is 200 MHz for the FPD510-FC-VIS and 500 MHz for the FPD610-FC-VIS.
The compact design of these detectors allows for easy OEM integration. These detectors feature a FC/PC input for fiber-coupled applications and include a power supply that has a universal AC input. To view Si detectors with free-space input, click here.
