Polarization-Independent Photonic Crystal Fabry–Perot Cavity

open access: yesIEEE Photonics Technology Letters, 2015
We present the design steps for 3D polarization-independent Fabry-Perot cavity. Inclusion of isolated dielectric rods into the limited number of holes at around the central region enables the generation of cavity that sustains both transverse electric and transverse magnetic modes.

High-extinction-ratio resonant cavity polarizer for quantum-optics measurements [PDF]

open access: yes, 2007
The use of a high-finesse Fabry-Perot ring cavity with an odd number of reflections as a high-extinction-ratio resonant polarizer is shown. Experimental results from quantum-noise measurements using resonant cavities as spatial and spectral filters and ...

A Self-Referenced Refractive Index Sensor Based on Gold Nanoislands

open access: yesSensors, 2022
We report on a self-referenced refractive index optical sensor based on Au nanoislands. The device consists of a random distribution of Au nanoislands formed by dewetting on a planar SiO2/metal Fabry–Pérot cavity.

Enhancing the modulation depth of a dynamic terahertz metasurface by integrating into an asymmetric Fabry-Pérot cavity

open access: yesAIP Advances, 2018
The modulation capability of a terahertz dynamic metasurface was enhanced by integrating it with an asymmetric Fabry-Pérot cavity. The dynamic metasurface consists of split ring resonators combined with high frequency metal semiconductor metal varactors.
