Microwave Photonic Signal Processing and Sensing Based on Optical Filtering

Abstract

Microwave photonics, based on optical filtering techniques, are attractive for wideband signal processing and high-performance sensing applications, since it brings significant benefits to the fields by overcoming inherent limitations in electronic approaches and by providing immunity to electromagnetic interference. Recent developments in optical filtering based microwave photonics techniques are presented in this paper. We present single sideband modulation schemes to eliminate dispersion induced power fading in microwave optical links and to provide high-resolution spectral characterization functions, single passband microwave photonic filters to address the challenges of eliminating the spectral periodicity in microwave photonic signal processors, and review the approaches for high-performance sensing through implementing microwave photonics filters or optoelectronic oscillators to enhance measurement resolution.

Processing, Characterization, and Impact of Nafion Thin Film on Photonic Nanowaveguides for Humidity Sensing

“…Microring resonators (MRRs), as a waveguide-based, monolithically integrated resonant interferometer having a small size, have attracted great interest in a wide range of applications including optical communications, signal processing, and sensing. [1][2][3] A generic integrated optical MRR consists of a ring waveguide as the resonant cavity and at least one bus waveguide that can couple light into the ring. When light propagates via the ring waveguide, the evanescent field extends outside of the waveguide and interacts with materials on the waveguide surface.…”

Performance Analysis of Dispersion Compensation Schemes with Delay Line Filter

“…Li.,L. et.al discussed about the use of ring resonators acting as passband microwave photonic filter in order to perform dispersion compensation [5]. Poornachari, P. et.al discussed about using Side Couple Integrated Space Sequence of Resonator (SCISSOR) acting as delay line based All Pass Filter for dispersion compensation [6].…”
