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.

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 ...

High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization

Advanced Photonics Research, EarlyView.
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

A Low‐Cost Curvature Detection Method for an Untethered Biped Pipeline Climbing Robot with Energy‐Efficient Strategy

Advanced Robotics Research, EarlyView.
A low‐cost pipeline curvature detection method has been proposed for an untethered biped pipeline surface climbing robot (BPCR) system with a five‐degree‐of freedom structure. The BPCR features adaptive vacuum suction cups equipped with multiple laser sensors on the suction modules to detect the curvature of various surfaces.
