known is an optical receiver in which first a received broadband optical signal is converted to a broadband electric signal by means of a optoelectric converter comprising a transimpedance amplifier , and thereafter a channel is selected from the converted broadband signal by means of a tuner which is coupled to the transimpedance amplifier . such a configuration is not optimal in fulfilling noise and bandwidth requirements . an optical receiver for subcarrier multiplexed optical signals is proposed which has a tunable frequency selective front - end section that is directly coupled to a photodiode as an optoelectric converter so as to selectively pass a tuned channel from the received subcarrier multiplexed optical signal to a succeeding amplifier .
