Abstract: We report our work on the fabrication and testing of AlGaInAs MQW lasers for space applications. A radiation test with 1.8MeV protons shows a lasing optical spectrum red shift. We conducted ...
Abstract: We present a compact and efficient method for directly coupling a near-ultraviolet laser diode with high beam ellipticity to a hollow core fiber (HCF) using an all-fiber mode field diameter ...
