WS2 Micro‐Dome Single Photon Source in a Tunable Open Cavity

Advanced Optical Materials, EarlyView.
In this work, a single‐photon source based on WS2 micro‐domes is realized and integrated into an open, tunable optical microcavity. Single‐photon emission from the coupled emitter–cavity system is observed. Detailed analysis shows that a pronounced acoustic phonon emission sideband contributes specifically to the non‐resonant emitter–cavity coupling in

Vertical-Cavity Surface-Emitting Laser With a Chiral Nematic Liquid Crystal Overlay

IEEE Photonics Journal, 2014
We demonstrate measurement results of the light emission of vertical-cavity surface-emitting lasers (VCSELs) with chiral liquid crystal (CLC) overlay (CLC-VCSEL). Two different CLC materials with different chiral-phase temperature range are presented and

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

Advanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Deterministic Integration of Quantum Emitters and Optical Cavities in a Van Der Waals Crystal

Advanced Optical Materials, EarlyView.
The work demonstrates fabrication of Circular Bragg Grating (CBG) cavities with embedded emitters in hBN. The cavities are fabricated around a pre‐characterised quantum emitter. The integrated platform enables light matter interaction and access to brighter emitters and spins in hBN.

Integrated plasmonic circuitry on a vertical-cavity surface-emitting semiconductor laser platform

Nature Communications, 2016
Integrated plasmonic sources are crucial in the development of plasmonic circuitry. Here, McPolin et al. show that vertical-cavity surface-emitting lasers can be employed as an on-chip, electrically pumped source or detector of plasmonic signals and also

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling

Advanced Optical Materials, EarlyView.
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...
