Abstract
Mixing of lightwaves and microwaves offers new perspectives for the reception of subcarrier multiplexed
(SCM) optical signals, Berceli (1). The received signal can be selected more easily and thus the receiver is significantly simplified. The new mixing method applying high-speed photodiodes presented in the paper is very promising because of its rather flat mixing response up to very high frequencies. Applying the new mixing process much higher subcarrier frequencies can be received thus enhancing the
SCM optical transmission capacity of such a system.
