THZ FABRY-PEROT SPECTROMETER [PDF]

open access: yesProceedings of the 2021 International Symposium on Molecular Spectroscopy, 2021
The development of Cavity-Enhanced Techniques and Cavity Ring Down Spectroscopy has allowed many sensitive infrared measurements to be undertaken. We have constructed a THz resonator with a high finesse to form the basis of a new instrument for sensitive cavity enhanced THz measurements.

Self-coherent optical transmission using a narrow linewidth tunable slotted fabry-perot laser [PDF]

open access: yes, 2010
A narrow linewidth slotted Fabry-Perot laser has been employed in a self-coherent optical transmission system. A comparison of the system performance of the tunable slotted laser with a SG-DBR laser has also been ...

Resonance characteristics of transmissive optical filters based on metal/dielectric/metal structures [PDF]

open access: yesКомпьютерная оптика, 2020
The resonance characteristics of the Fabry-Pérot resonator modes supported by metal/dielectric/metal planar structures are studied in the case of absorbing media for near-to-normal light incidence.

Fabry-Perot Observations of Cen A [PDF]

open access: yesSymposium - International Astronomical Union, 1987
We present Fabry–Perot spectrophotometry of the well-known peculiar galaxy Cen A (NGC 5128). The observations were carried out using the Rutgers Fabry–Perot system and a CCD as a detector. We scanned the Hα and [NII] (λ6583) emission lines. From these data we were able to construct maps of the continuum, line emission, velocity and velocity dispersion.

Multimode Fabry-Perot laser as a reservoir computing and extreme learning machine photonic accelerator

open access: yesNeuromorphic Computing and Engineering, 2023
In this work, we introduce Fabry–Perot lasers as neuromoprhic nodes in the context of time-delayed reservoir computing and extreme learning machine (ELM) for the processing of temporal signals and the high-speed classification of images.

Ultra-high-sensitivity two-dimensional bend sensor [PDF]

open access: yes, 2006
A multicore fibre Fabry-Perot-based strain sensor interrogated with tandem interferometry for bend measurement is described. Curvature in two dimensions is obtained by measuring the difference in strain between three co-located low finesse Fabry-Perot ...

A novel approach to interface high-Q Fabry–Pérot resonators with photonic circuits

open access: yesAPL Photonics, 2023
The unique benefits of Fabry–Pérot resonators as frequency-stable reference cavities and as an efficient interface between atoms and photons make them an indispensable resource for emerging photonic technologies.

The many facets of the Fabry–Perot [PDF]

open access: yesEuropean Journal of Physics, 2016
We address the response, both in amplitude and intensity, of a Fabry-Perot from a variety of viewpoints. These complementary pictures conspire to achieve a comprehensive and consistent theory of the operation of this system.
