Fabry-Perot enhanced Faraday rotation in graphene

open access: yes, 2013
We demonstrate that giant Faraday rotation in graphene in the terahertz range due to the cyclotron resonance is further increased by constructive Fabry-Perot interference in the supporting substrate.

Impedance‐Matched High‐Overtone Thickness‐Shear Bulk Acoustic Resonators With Scalable Mode Volume

open access: yesAdvanced Science, EarlyView.
A bottom‐electrode‐free high‐overtone bulk acoustic resonator is achieved by lateral excitation of antisymmetric thickness‐shear modes on a lithium‐niobate‐on‐silicon platform. Planar electrode geometry eliminates conventional loading along the resonance path and confines acoustic energy within the electrode gap.

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

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.

Composite-cavity-based Fabry-Perot interferometric strain sensors

open access: yesOptics Letters, 2007
A composite-cavity-based Fabry-Perot interferometric strain sensor system is proposed to gain the minimum cross sensitivity to temperature and a high multiplexing capability at the same time. The interrogation of the sensor system is based on a white-light interferometric technology, and the demodulation is achieved by analyzing the coherence spectra ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

An inhibited laser

open access: yesCommunications Physics, 2022
Lasers in general are operated using a cavity resonant with emitters. In this study, the authors demonstrated a laser operating under an anti-resonant condition, where the emitter resonance is equally detuned from two Fabry–Perot fringes.
