ABSTRACT In this paper, we studied the performance degradation of single-carrier and dual-carrier 100 Gb/s and 400 Gb/s systems due to optical filter cascade with 50 and 100/150 GHz channel spacing, respectively. Eye closure penalty (ECP) is used as a performance evaluation metric, where we use two types of filters: fiber Bragg grating (FBG) and thin-film filters (TFF). Simulation results indic...

Color filters are widely used in color displays, optical measurement devices, and imaging devices. Conventional color filters have usually only one fixed output color. However developing active color filters with controllable color output can lead to more compact and sophisticated color filter-based devices and applications. Recent progress in nanotechnology and new knowledge of the interaction...

Multimodal multiplex spectroscopy (MMS) has been demonstrated to increase the optical throughput of a spectrometer as opposed to that of conventional optical spectrometers [5] and has been implemented using three-dimensional photonic crystals [5] and spherical-beam volume holograms recorded in the transmission geometry [6-7, 9] as spectral diversity filters. While such efforts have resulted in ...

Second and third-order monolithically integrated coupled ring bandpass filters are demonstrated in the InP-InGaAsP material system with active semiconductor optical amplifiers (SOAs) and current injection phase modulators (PMs). Such integration achieves a high level of tunability and precise generation of optical filters in the RF domain at telecom wavelengths while simultaneously compensating...
