Abstract:

Optical receivers for laser communication systems needs to have high detection sensitivity
so that allowable distance between transmitting and receiving stations can be maximized.
 In this study, a highly sensitive optical receiver will be developed which includes
the following features:  State-of-the-art SiAPD's with extremely low ionization constant
ratio for Ion noise operation, low noise GaAs MESFETS as amplifying devices, and
thin film circuit construction techniques.  A sensitivity analysis will be carried
out, which will be supported by experimental results from preliminary circuit fabrication
and evaluation.
