Reconfigurable, Defect-Free, Ultrahigh-Q Photonic Crystal Microcavities for Sensing

Sensors, 2013
We propose a new approach for creating reconfigurable high-Q cavities in defect-free photonic crystal slabs (PCSs). The approach relies on selective air-hole infiltration in otherwise defect-free PCSs.

Polarization‐Independent Single‐Band Guided‐Mode Resonance InGaAs Photodetector Array for Snapshot Multispectral Sensing

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Here, we report a single‐band guided‐mode resonance (GMR) InGaAs photodetector (PD) array. The device consists of an InGaAs PD with an ultrathin absorption layer bonded onto a Si 2D grating. Although a 2D crossed‐grating inherently supports many more optical modes than a 1D grating, we realized a single‐band response by introducing novel design ...

Second‐Harmonic Generation Enhancement in Polar Dielectric Films via Nonlocal Longitudinal Modes and Berreman Modes

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Nonlocal longitudinal resonances in ultrathin AlN enable thickness‐controlled harmonic matching between a resonance at the fundamental frequency and the Berreman resonance at the second‐harmonic frequency. The resulting simultaneous field enhancement at both frequencies substantially amplifies the predicted second‐harmonic response, revealing a double ...

Cavity quantum electrodynamics with moiré photonic crystal nanocavity

Nature Communications
Due to the existence of flatbands within the band structure, twisting photonics introduces a possibility to enhance the interaction between excitons in single QDs and cavity photons because of the extremely high quality factor (Q) in theory. In this work,

Operation of an InAs quantum-dot embedded GaAs photonic crystal slab waveguide laser by using two-photon pumping for photonics integrated circuits

AIP Advances, 2016
The development of small sized laser operating above room temperature is important in the realization of optical integrated circuits. Recently, micro-lasers consisting of photonic crystals (PhCs) and whispering gallery mode cavities have been ...

Design and Numerical Evaluation of a Highly Selective CMOS-Compatible Mid-IR Thermal Emitter/Detector Structure Using Optical Tamm-States

Proceedings, 2018
In this work we propose and evaluate a concept for a selective thermal emitter suitable for monolithic on-chip integration suitable for fabrication by conventional CMOS-compatible processes. The concept is based on our recently presented work on vertical-
