Abstract :
A novel coherent receiver for linear optical phase demodulation is proposed and experimentally demonstrated. The receiver, based on a broadband optical phase-lock loop has a bandwidth of 1.45 GHz. Using the receiver in an analog link experiment, a spurious free dynamic range of 125 dBHz2/3 is measured at 300 MHz. Further, theoretical investigations are presented demonstrating receiver operation at high frequencies (>2 GHz) using a sampling phase-locked loop.
