Abstract :
Good quality transmission of three television channels employing multiplexed UHF subcarriers at 770, 800 and 830MHz using a commercially available laser diode is demonstrated. Both the third-order intermodulation products and crossmodulation products of the laser are found to be better than ¿65dB. An SNR per channel of 52dB has been obtained.
