Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

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

Below 1% Reflectance for Black GaAs Surface Prepared by Facile Two‐Step Wet Chemical Treatment: Hydrogen Peroxide and Water

Advanced Photonics Research, EarlyView.
Black GaAs surface which decreases light reflectivity forms in surprising way when GaAs is kept first in hot hydrogen peroxide solution and then in hot‐water solution. To increase performance of many photonic devices (e.g., solar cell, light emitting diode (LED), photodetector), it is essential to decrease light reflection at device interfaces ...

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

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

Advanced 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.
