Frequency locking of an erbium-doped fiber ring laser to an external fiber Fabry-Perot resonator [PDF]

open access: yes, 1993
An all-fiber, single-frequency, erbium-doped ring laser has been frequency locked to a resonance peak of an external fiber Fabry-Perot resonator by the Pound-Drever technique.

Directional Microstrip Antenna by using Metamaterial Superstrate in Fabry-Perot Cavity [PDF]

open access: yesمجله مدل سازی در مهندسی, 2015
Recently Fabry-Perot (FP) resonator structures for enhancing directivity have found wide use in antenna design. FP Resonator antenna generally consists of primary radiator backed with a metal ground plane and a partially reflective surface (PRS). In this

Photothermal effects in ultra-precisely stabilized tunable microcavities

open access: yes, 2016
We study the mechanical stability of a tunable high-finesse microcavity under ambient conditions and investigate light-induced effects that can both suppress and excite mechanical fluctuations.

Interferometry and Laser Control with Solid Fabry-Perot Etalons [PDF]

open access: yes, 1966
The use and analysis of solid Fabry-Perot etalons for interferometry and laser control are discussed and supported with experimental data. Low angle scattering is found to be an important factor influencing finesse and peak transmission.

Optimised Fabry-Perot (AlGa)As quantum well lasers tunable over 105 nm [PDF]

open access: yes, 1989
Uncoated, Fabry-Perot (AlGa)As semiconductor lasers are tuned over 105nm in a grating-coupled external cavity. Broadband tunability is achieved by optimising the resonator loss so as to invoke lasing from both the first and second quantised states of the

Microwave limb sounder [PDF]

open access: yes, 1981
Trace gases in the upper atmosphere can be measured by comparing spectral noise content of limb soundings with the spectral noise content of cold space. An offset Cassegrain antenna system and tiltable input mirror alternately look out at the limb and up

Multimode optomechanical system in the quantum regime

open access: yes, 2016
We realise a simple and robust optomechanical system with a multitude of long-lived ($Q>10^7$) mechanical modes in a phononic-bandgap shielded membrane resonator.

Cavity cooling of a nanomechanical resonator by light scattering [PDF]

open access: yes, 2008
We present a novel method for opto-mechanical cooling of sub-wavelength sized nanomechanical resonators. Our scheme uses a high finesse Fabry-Perot cavity of small mode volume, within which the nanoresonator is acting as a position-dependant perturbation

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

High-Q Fabry–Pérot Micro-Cavities for High-Sensitivity Volume Refractometry

open access: yesMicromachines, 2018
This work reports a novel structure for a Fabry–Pérot micro cavity that combines the highest reported quality factor for an on-chip Fabry–Pérot resonator that exceeds 9800, and a very high sensitivity for an on-chip volume refractometer based on a Fabry ...
