Broadband Measurement and Tuning of the Volatile Thermo‐Optic Properties in Chalcogenide Phase Change Materials

Advanced Optical Materials, EarlyView.
Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.

Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy

Advanced Optical Materials, EarlyView.
This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual

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.
