Method and generating optical polar return-to-zero amplitude modulation signal using reflective semiconductor optical amplifier and wavelength-division-multiplexed passive optical network system using the same


The present invention can operate a reflective semiconductor optical amplifier at ultrahigh speed using a polar return-to-zero (rz) modulation method, and operate a reflective semiconductor optical amplifier (rsoa) whose modulation bandwidth is limited at ultrahigh speed by generating signals vertically symmetrical using a newly suggested polar rz signal generator when generating an amplitude modulation signal at a transmission end. The present invention can overcome the problem that a modulation speed cannot be increased to 10 gb/s or above due to signal distortion by inter-symbol-interference when generating an ultrahigh speed amplitude modulation signal using an rsoa of low price having a very narrow modulation bandwidth in an rsoa-based optical network.
