Abstract :
A hybrid p-i-n-FET combination of InGaAs photodiode and InP MISFET has been evaluated for medium-speed (<1 Gb/s) optical fiber communication links. This combination provides a very attractive low-noise performance, comparable to the best GaAs FET based hybrids. The results obtained imply that monolithic p-i-n-FETs with optimum performance can be designed with InP channel transistors instead of InGaAs-based FETs, which exhibit excess gate leakage and low-frequency excess noise due to the small band gap. However, it was found that heterostructure FETs with InP channel still produce an appreciable amount of low-frequency noise, even though the excess gate current is suppressed.<>
