A miniature Nd: Y AG laser and an intensity modulator based VSB-AM video signal transmitter is described. With a light source having RIN level below -170 dB/Hz, the system allows a relatively low modulation index to be used. For a 40 channel system using a standard MZ, a CTB = 60 dB corresponds to ID;= 1%. With 75 mW Nd:YAG laser source, a system with power budget of 5.5 dB and SO dB CNR is realizable. Several promising techniques of modulator linearization are also given.
