Abstract
For long-distance transmission systems at longer wavelengths, several kinds of photodiode and low-noise amplifier have been studied. Since a combination of an indium gallium arsenic phosphorus avalanche photodiode (InGaAsP/InP-APD) and a high-impedance preamplifier using GaAs MES-FET (FET) is expected to result in a highly sensitive receiver, we studied an optimum conditions of the receiver design.
