Ultraviolet Narrowband Photomultiplication Type Organic Photodetectors with Fabry−Pérot Resonator Architecture

Advanced Functional Materials, 2022
Ultraviolet (UV) narrowband photodetectors play a critical role in missile detection, flame monitoring, optical communication, etc. It is a great challenge to realize UV narrowband organic photodetectors due to wide photo‐harvesting property of organic ...

Dual-Band Aperture-Shared Fabry–Perot Cavity-Integrated Patch Antenna for Millimeter-Wave/Sub-6 GHz Communication Applications

IEEE Antennas and Wireless Propagation Letters, 2022
This letter presents a dual-band antenna with a large frequency ratio of 11.7 (2.4 GHz/28 GHz) by integrating an mm-wave Fabry–Perot cavity (FPC) antenna into a sub-6 GHz patch antenna. The patch with periodic slots functions as both the 2.4 GHz radiator

Multiplex Fabry-Perot interferometer

SPIE Proceedings, 1991
The Fabry-Perot interferometer (FPI) traditionally has been used to examine either small spectral ranges or relatively imple spectra. Recently, however, studies have shown that the FPI can be competitive with the Michelson interferometer ver extended spectral ranges.

Electrooptical Fabry-Perot Spectroscopy

Applied Optics, 1973
A new method is described that uses an elegtronic imaging tube to record and explore Fabry-Perot fringes. The light intensity distribution of an interference pattern and the Doppler effect of a line can be observed with an exploration time of the order of 1O(-5) sec.

Fabry-Perot recycling spectrometer

Applied Optics, 1976
A new type of Fabry-Perot spectrometer has been developed to achieve multichannel operation with recovery of the light that is lost in conventional systems. The light reflected from the interferometer is recycled in a predetermined way using small right angle prisms.

Jamin Fabry–Perot interferometer

Optics Letters, 2003
A novel type of interferometer was designed and tested experimentally. It combines the advantages of the spatial path separation used in the two-wave polarized Jamin interferometer and the high sensitivity that characterizes the multiwave Fabry-Perot interferometer. Furthermore, when it is sandwiched between crossed polarizers it shows a sensitivity to

Temperature-Compensated Refractive Index Measurement Using a Dual Fabry–Perot Interferometer Based on C-Fiber Cavity

IEEE Sensors Journal, 2020
We demonstrate a simple-to-fabricate, temp- erature-compensated refractive index sensor using a dual Fabry–Perot optical fiber interferometer using C-fiber.
