Single and Bi‐Layer Glass‐Based Phantoms: Robust Materials for a Calibration Standard for Fluorescence Imaging Systems

Advanced Photonics Research, EarlyView.
Fluorescence‐guided surgery is a common technique and characterizing imaging performance is important to ensure clinical reliability. A calibration standard comprising multiple glass phantoms fabricated to mimic the optical properties of fluorescent and non‐fluorescent tissue is presented.

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

Advanced 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

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...
