Engineers have developed the first room-temperature, eye-safe, photopumped PCSEL by embedding silicon dioxide into photonic crystal layer.

We experimentally investigate the laser linewidth tolerance of 32-GBaud DP-256QAM system for back-to-back and 50-km transmission. Results show that laser linewidth (0.1~550 kHz) has only slight effect ...

Scientists have reimagined the meaning of a "light meal," creating microlasers that use natural products to emit illuminated beams through food. And they're completely edible. These mini lights, the ...
