Directly modulated semiconductor lasers represent a crucial technology in modern optical communications, where the injection current is directly varied to encode information onto the laser output.

Metasurfaces are highly versatile for manipulating the amplitude, phase, or polarization of light. During the last decade, metasurfaces have been proposed for a vast range of applications — from ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...
