Optical digital filters that employ optical delay lines are proposed. Properly locating the zeros in the transfer function is shown to enable interleaver pairs to be designed with the same amplitude r...
Channelized Dispersion-Compensating Grating by Periodic Continuous Phase and Amplitude Modulatio
Channelized Dispersion-Compensating Grating Periodic Continuous Phase Amplitude Modulatio
2015/8/4
A novel phase and amplitude modulation scheme for channelized dispersion compensating gratings is presented.Measurement data from fabricated gratings show low group-delay ripple and low insertion-loss...
Experimental Demonstration of Compensating the I/Q Imbalance and Bias Deviation of the Mach-Zehnder Modulator for an RF-Tone Assisted Optical OFDM System
Compensating I/Q Imbalance Bias Deviation Mach-Zehnder Modulator RF-Tone Assisted Optical OFDM System
