Abstract
Characterization of 10 Gb/s RZ-BPSK signal was demonstrated by measuring complex constellation diagram, chirp, and intensity profile using coherent homodyne detection with a cw local oscillator from the same laser source for optical data modulation. A new stabilization method was used for the homodyne detection. This measurement technique can be used for the characterization and diagnostic of a transmitter based on BPSK at transmission site.
