Room‐Temperature Polariton Condensation Into Superscar Modes in Growth‐Defined Triangular Micro‐Prism Resonators

Laser &Photonics Reviews, EarlyView.
High‐Q superscar modes in growth‐defined triangular GaN micro‐prism resonators enable strong exciton–photon coupling and room‐temperature polariton condensation, offering a scalable platform for integrated III‐nitride polariton devices. ABSTRACT Group III‐nitride semiconductors are regarded as key materials for realizing polariton devices operating at ...

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Experimental demonstration of a suspended, diffractively coupled Fabry‚ Perot cavity [PDF]

, 2010
Diffraction gratings have been considered as input couplers for Fabry-Perot cavities in future gravitational wave detectors. We experimentally demonstrate the use of a triple-suspended, diffractively coupled cavity and examine conventional Pound-Drever ...

On-Chip High-Finesse Fabry-Perot Microcavities for Optical Sensing and Quantum Information

Sensors, 2017
For applications in sensing and cavity-based quantum computing and metrology, open-access Fabry-Perot cavities—with an air or vacuum gap between a pair of high reflectance mirrors—offer important advantages compared to other types of microcavities.

Transmission‐Mode Silicon‐Rich Nitride Mie‐Void Metasurfaces in the Visible

Laser &Photonics Reviews, EarlyView.
Transmission‐mode Mie‐void metasurfaces are demonstrated in silicon‐rich nitride, where localized void resonances hybridize with slab‐guided and Fabry–Pérot‐like modes in a finite film, producing a quantified avoided crossing between coupled modes. Controlled void depth tunes the visible transmission spectrum, enabling structural color and spatial ...

High-Temperature Sensor Based on Fabry-Perot Interferometer in Microfiber Tip

Sensors, 2018
A miniaturized tip Fabry-Perot interferometer (tip-FPI) is proposed for high-temperature sensing. It is simply fabricated for the first time by splicing a short length of microfiber (MF) to the cleaved end of a standard single mode fiber (SMF) with ...

Integration of III‐V Quantum Dot Photonic Devices on Silicon Nitride via Lithography‐Aligned Micro‐Transfer Printing

Laser &Photonics Reviews, EarlyView.
Lithography‐aligned micro‐transfer printing integrates unprocessed InAs/GaAs quantum dot membranes with silicon nitride photonic circuits. Post‐transfer patterning defines quantum dot photonic devices directly on the target chip, enabling precise GaAs–SiNx coupling, purcell‐enhanced single photon emission, and scalable on‐chip routing and correlation ...

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

Laser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.
