Abstract :
Multiwavelength and power-equalized operation is demonstrated in a semiconductor optical amplifier ring laser that uses a fiber Fabry-Perot filter. By using single-pass optical feedback, the power-equalized oscillating spectrum is broadened so that simultaneous oscillation of 52 lines spaced at 50 GHz is achieved. The lines had 500 MHz width were power-equalized to within 0.3 dB and the extinction was better than 32 dB.
