Abstract :
Reported is an experimental fiber-optic analog link with an electrical insertion loss of 34 dB at 20 GHz, a noise figure of 41 dB, and an intermodulation-free dynamic range of 108 dB/Hz/sup 2/3/. The link uses a diode-pumped Nd:YAG laser, a bandpass integrated-optical intensity modulator, and a p-i-n detector; it contains no amplifiers.<>
