Passive edge filter design using Erbium-Doped fiber

, 2017
In this study, Passive Edge Filter was designed using Erbium Doped Fiber. When this design was done, simulation was performed to monitor gain changes with respect to -5, -10, -15, -20 dBm input signal power and varying lengths of 16 EDF which design by ...

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

Passive, wavelength self-adjusting and tracking optical filter

, 1994
A passive, self-adjusted filter is presented which consists of an unpumped, twin-core erbium-doped fibre. The filter characteristics depend on the fibre and optical parameters. For a fibre NA of 0.3, the optimum filter performance is achieved for average

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.
