A 10 Gb/s high sensitivity optical receiver using an InGaAs-InAlAs superlattice APD at 1.3 mu m/1.5 mu m

A description is given of the high-speed low-noise operation of an optical receiver using an InGaAs-InAlAs superlattice avalanche photodiode (SL-APD) that has high sensitivity at 1.3 mu m/1.5 mu m wavelength. A minimum detectable power of -24.0 dBm is obtained at a bit rate of 10 Gb/s. This is the best sensitivity ever reported at 10 Gb/s from APDs.>
