Improved 808-nm High-Power Laser Performance With Single-Mode Operation (Vertical Direction) in Large Optical Cavity Waveguide

IEEE Photonics Journal, 2018
We present a detailed study of the effect of large optical cavity (LOC) waveguide design on the laser's kink performance and it was found that a multimode waveguide in the epi growth direction could lead to the occurrence of the power kink in the ...

Shortcuts to adiabaticity in waveguide couplers–theory and implementation

Advances in Physics: X, 2021
Adiabatic processes are ubiquitous in physics and engineering. A drawback of such processes is that they tend to be slow, either in time–for atomic systems, for example–or in space–for photonic systems. A number of techniques have been developed over the

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
