ASK Multiport Optical Homodyne Receivers

Several types of ASK multiport homodyne receivers are investigated, and the impact of the phase noise and of the shot noise on these receivers is analyzed. The simplest structure is the conventional multiport receiver with a matched filter in each branch. This structure can tolerate AvT (Av is the laser linewidth and T is the bit duration) of several percent with a small power penalty (3.6 perc...
