Abstract

A suppressed carrier modulator was incorporated into a fiber ring oscillator as an intracavity suppressed carrier transmitter for coherent analog optical links. With a DCFR and an UNBF, a single mode ring laser operation was observed and a SFDR of 105 dB/Hz2/3 was demonstrated. Further improvement on SFDR is possible if higher optical power is applied to MZ as well as balanced photodetector and low loss side-band filter are used. This novel suppressed carrier transceiver could provide a significantly larger SFDR than is possible using direct detection or conventional coherent detection. Ultimately, this transceiver scheme may be developed into an ultra-compact total on-chip design for applications.
