Polarization-Independent Photonic Crystal Fabry–Perot Cavity

IEEE 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.

Performance of a 1200 m long suspended Fabry–Perot cavity [PDF]

Classical and Quantum Gravity, 2002
Using one arm of the Michelson interferometer and the power recycling mirror of the interferometric gravitational wave detector GEO600, we created a Fabry-Perot cavity with a length of 1200 m. The main purpose of this experiment was to gather first experience with the main optics, its suspensions and the corresponding control systems.

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Fano resonance of nanoparticles embedded in Fabry-Perot cavities

Optics Express, 2013
We present an optical structure, which consists of metal nanoparticles embedded in Fabry-Perot (F-P) cavity, to investigate the Fano resonance, which originates from the interaction between F-P mode and the plasmon modes supported by the nanoparticles.
