Abstract: Chaotic laser with a flat power spectrum up to 32.3 GHz has been generated by using a dual-wavelength optically injected Fabry–Pérot laser diode with optical feedback. The Fabry–Pérot laser ...

Abstract: 5-Gb/s optical PSK (phase-shift keying) homodyne detection experiments are discussed. In these experiments, the optical carrier is recovered by a Costas optical phase-locked loop using a ...

Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, ...

A deep dive into two legendary 1990s CD players—the Copland CDA 288 and YBA CD1 Blue Laser. Vintage, overbuilt, and sonically elite, these eccentric European classics still rival modern digital ...
