Wideband, high-fidelity analog optical link design

摘要

An analog optical link (10) that provides high-fidelity over bandwidths greater than 1 GHz is presented. The analog optical link (10) includes a transmitter (18) having an optical modulator (20) and a receiver (16) having an optical demodulator (12). In one embodiment, the modulator (20) is a phase modulator (20) and particularly a pre-emphasis phase modulator (20) that operates as a frequency modulator at low frequencies. The demodulator (12) is a frequency demodulator (12) that includes a feed-forward function for cancelling noise.
