PDL and PMD Emulation with Control of Amplitude and Spectral Dependence to a Sub-Channel Level across the C-Band
Optical instruments Optical communications
2015/5/25
We present results of a polarization diverse LCoS wavelength processor. Applications include impairment simulation of broadband, channelized and intra-band PMD and PDL for detailed experimental sensit...
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...
Direct measurement of amplitude and phase temporal responses of ultrahigh-speed optical modulators
amplitude phase temporal responses ultrahigh-speed optical modulators
2015/7/31
We demonstrate a direct measurement of the complex ultra-fast temporal response of optical modulators (with a bandwidth ～ 40GHz in the reported example) enabling real-time characterization of instant...
