Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

open access: yesAdvanced Photonics Research, EarlyView.
Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced.

940 nm Micro‐Light‐Emitting Diode Fabricated on Industry‐Compatible 300 mm Si (100) Substrate by Metal–Organic Chemical Vapor Deposition

open access: yesAdvanced Photonics Research, EarlyView.
The fabrication of 940 micro‐light‐emitting diodes on both 300 mm Si and Ge/Si wafers has been demonstrated using direct metal–organic chemical vapor deposition epitaxy. These promising results show the potential for monolithic integration of III‐As onto complementary metal‐oxide‐semiconductor (CMOS)‐compatible silicon platforms. This achievement opens

CMOS‐Compatible Short‐Wave Infrared Linear Arrays of Ge‐on‐Si Avalanche Photodiodes

open access: yesAdvanced Photonics Research, EarlyView.
The fabrication and characterization of a new type of surface‐illuminated Si‐based avalanche photodiode array operating in the short‐wave infrared region using germanium as the absorber and silicon as the multiplier is reported. The demonstration of an avalanche gain of 24 at a temperature of 378 K allows the devices to operate in outdoor environments.

Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence

open access: yesAdvanced Photonics Research, EarlyView.
Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.
