Terahertz Fabry-Perot Cavity Leaky-wave Antennas
2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring), 2019In this work we examine the recent efforts made in the design of either efficient or reconfigurable Fabry-Perot cavity leaky-wave antennas (FPC-LWAs) in the terahertz (THz) range. We start by discussing the radiating performance of an FPC-LWA consisting of a grounded dielectric slab (GDS) covered with a periodic arrangement of fishnet-like unit cells ...

Optimization of a Fabry-Perot cavity antenna
2015 International Workshop on Antenna Technology (iWAT), 2015We propose a new method to increase both an antenna input reflection coefficient (S11) and overall efficiency of a Fabry-Perot cavity (FPC) antenna. In general, the FPC antenna consists of a partially reflective superstrate and a metal ground plane. By finding optimum arrangement of unit cells in the superstrate, we prove that we can largely widen an ...

Behavior of cholesteric liquid crystals in a Fabry–Perot cavity
Optics Letters, 1999We investigate the behavior of cholesteric liquid crystals (CLC's) inside a Fabry-Perot (FP) cavity. Although FP cavities filled with various liquid crystals have been extensively studied, to our knowledge the behavior of CLC-based FP cavities has not been reported.

Cavity QED in microsphere and Fabry-Perot cavities
2003A long-standing ambition in the field of cavity quantum electrodynamics has been to trap single atoms inside high-Q cavities in a regime of strong coupling. Our goal has been to develop techniques for trapping that are compatible with strong coupling and that do not interfere with the cavity QED interactions.

Modeling and analysis of an extrinsic Fabry–Perot interferometer cavity
Applied Optics, 2005A schematic representation of optical feedback between two resonator mirrors undergoing a phase shift each round trip as a function of the separation of the mirrors is studied. A transfer function modeling of the extrinsic Fabry-Perot interferometer (EFPI) is presented.

Double-cavity electrooptic Fabry-Perot tunable filter
Applied Optics, 1982The experimental development of an infrared multiple-cavity electrooptically tuned Fabry-Perot filter using LiNbO(3) is described. This filter, designed for operation in the 3-5-microm spectral band, was demonstrated by angle scanning using a He-Ne laser at 3.39 microm.

Fabry-Perot Cavities in Advanced Virgo
2018So far the working principle of the Advanced Virgo detector has been presented, as well as a detailed overview of its different subsystems. This chapter will give a detailed description of the Advanced Virgo Fabry-Perot arm cavities, introducing the basic concepts needed to understand the challenges of their commissioning.

In-fiber chirped Fabry–Perot cavity for temperature sensing
Optics LettersMeasurement resolution and dynamic range of conventional optical fiber sensors are often mutually restricted. In this work, an in-fiber chirped Fabry–Perot cavity (interferometer) is proposed, for the first time to our knowledge, to resolve the conflict between the resolution and dynamic range.
