Abstract :
A wide optical-input dynamic range is demonstrated for an inverted p-down InAlAs/InGaAs avalanche photodiode. The 3 dB down bandwidth maintains a value as high as 18 GHz for an input optical power level of up to + 2.5 dBm. Such high-power tolerance meets the requirements of various future optical fibre communications systems such as 100 Gbit/s Ethernet which has a serial baud rate of 25 Gbit/s.
