High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within

Photolithography-Compatible Three-Terminal Superconducting Switch for Driving CMOS Loads [PDF]

open access: yesarXiv
Superconducting devices have enabled breakthrough performance in quantum sensing and ultra-low-power computing applications. However, the need for a cryo-electronics platform that can interface superconducting electronics with Complementary Metal-Oxide-Semiconductor (CMOS) devices has become increasingly evident in many cutting-edge applications.

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

open access: yesAdvanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Energy Focusing Metasurface Based Wireless Power Transfer System for Compact Unmanned Mobilities

open access: yesAdvanced Optical Materials, EarlyView.
A miniaturized wireless power transfer system integrates a metasurface lens, microstrip patch antenna, and RF‐CMOS rectifier to enhance mmWave reception efficiency and reduce size. Leveraging mmWave short wavelengths, it achieves high gain on small platforms. The system's polarization independence and wide‐angle reception ensure robust performance.
