A suspended chalcogenide waveguide achieves record ppb-level gas detection in the near-infrared, enhancing sensitivity for portable environmental monitoring.
Abstract: We experimentally demonstrate a flexible optical interconnect in O-band by using intensity modulation and direct detection (IM/DD) with probabilistically shaped eight-level pulse amplitude ...
Nuclear magnetic resonance –based co-magnetometers are essential tools for applications ranging from inertial navigation to geophysical exploration and biomedical sensing. Their performance critically ...
Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this ...
Abstract: This work first establishes an 8-channel four pulse amplitude modulation (PAM-4) intensity modulation direct detection (IM-DD) optoelectronic transceiver system, with cascaded silicon ...
ABSTRACT: This paper presents a comparative study of four Sinusoidal Pulse Width Modulation (SPWM) strategies Phase Disposition (PD-PWM), Phase Opposition Disposition (POD-PWM), Alternate Phase ...
The terahertz range sits between microwaves and infrared light on the electromagnetic spectrum. Despite the potential of terahertz waves in many fields, for example in walk-through security scanners ...
Evaluating the aerodynamic profile of a hypersonic projectile requires multiple ultra-high camera stations positioned along the flight path. To arrest image motion typically requires exposure time of ...
Patients suffering from depression, anxiety and trauma-related disorders experienced significant relief from their symptoms after a new treatment that uses sound waves to modulate deep brain activity, ...
