Passband filtering and in-band crosstalk penalties are investigated using WSS filter shapes fitted using a supergaussian model and an analytical model. The analytical model is determined to be more accurate than the supergaussian model for stopband fitting and crosstalk penalty assessment.
A microwave photonic filter that uses an uncooled Fabry-Perot (FP) laser as the optical source is presented, which can realize low-pass magnitude response and wide passband characteristic, by optically shaping the laser signal. The configuration can overcome the frequency and power drift of the uncooled FP laser by using a feedback structure. Experimental results demonstrate a 6-tap microwave photonic...
We have demonstrated a microwave photonic phase shifter that implements uncooled distributed feedback lasers as the optical source, and emulate the performance of this device in a microwave photonic beamformer system after compensating the temperature fluctuations by using the proposed configuration.
In this paper, we investigate and study the performance of a WDM-based 60 GHz mm-wave fiber-wireless link incorporating a liquid-crystal-on-silicon (LCoS)-based programmable optical processor (POP) in the remote node (RN) for demultiplexing and processing of multiple channels. To ensure that the fiber-wireless link is compatible with existing WDM optical backbones, we have evaluated the performance...
We demonstrate a method of filtering broadband ASE to emulate high bit rate optically modulated signals, allowing accurately shaped artificial channels to be loaded into a channel plan for optical networks.
Spectral modeling of wavelength selective switches (WSS) has previously used supergaussian functions to predict the channel bandshape. We show that an error function-based model produces a much more accurate representation of WSS channels, and allows greater utility and ease of use for modeling flexible bandwidth channel plans for next generation optical networks.
