TL;DR: A model for characterizing the spectral response of the passband of Wavelength Selective Switches is presented and it is demonstrated that, in contrast to the commonly used supergaussian model, the presented model offers a more complete match to measured results.

TL;DR: In this paper, a microwave photonic filter that realizes a high-resolution bandpass filter response with coherence-free operation and without the limitations of phase-induced intensity noise is presented.

TL;DR: The requirements for automotive LIDAR are analyzed and a novel taxonomy of classifying different beamsteering methods is suggested, which suggests a novel approach to classification of beamsteered methods for fully autonomous vehicles.

TL;DR: In this article, the authors describe a system and methods of enhancing channel bandwidth in an optical system having a number of wavelength selective switching (WSS) devices by spatially dispersing the wavelength channels of the optical signals, projecting the spatially dispersed channels onto corresponding predetermined regions of an optical manipulation matrix including a plurality of individually addressable manipulating elements, determining a modification function that specifies a state for each manipulating element within the predetermined region, and driving the elements of the corresponding regions at states specified by the function to selectively modify the channel band shape such that the received channel's bandwidth is

TL;DR: In this article, the authors describe experimental demonstration of 50GHz ROADM tolerance for a real-time, single-carrier, 127-Gb/s coherent PM-QPSK system.
