TL;DR: In this article, the authors introduce the basic physical concepts of cavity optomechanics, and describe some of the most typical experimental cavity optOMEchanical systems for sensing applications, and discuss the noise arising from various sources.

TL;DR: Various practical aspects of implementing AWGs as astronomical spectrographs are discussed, including the coupling of the light between the fibers and AWGs, high-temperature annealing to improve the throughput of the devices at ~1500 nm, and a novel algorithm to make the devices polarization insensitive over a broad band.

TL;DR: In this article, a complex waveguide bragg grating (CWBG) was designed to generate an arbitrary transmission spectrum, which can be used for eliminating OH emission lines from the Earth's atmosphere for ground-based astronomical observations.

TL;DR: In this paper, a novel approach is developed for measuring small losses in highly transparent Si3N4/SiO 2 waveguides on a silicon chip by measuring the transmission of an optical cavity formed by two highly reflective Bragg gratings and a uniform waveguide between the two gratings whose length can be varied to increase the loss fitting accuracy.

TL;DR: In this paper, a 1.5/spl mu/m wavelength superluminescent light source operating at a heat sink temperature of 13/spl deg/C with the following properties was realized: 20mW continuous wave output power, 130-nm spectral bandwidth, and 0.2dB spectral modulation.
