Figure 1. Schematic of a tunable microlaser based on phase-change perovskite gain medium, sandwiched between Au mirror and DBR reflector sitting on a quartz glass substrate, pumped by blue-violet ...
A new ring-based tunable laser on a chip emits multiple wavelengths smoothly, offering a compact, cost-effective alternative for sensing, diagnostics, and more. (Nanowerk News) Researchers in the ...
A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...
