First demonstration of InGaP/InAlGaP based 608nm orange laser and 583nm yellow superluminescent diode

We report on the first demonstration of InGaP/InAlGaP based orange semiconductor laser (OSL) and yellow superluminescent diode (YSLD) emitting at a wavelength of 608nm and 583nm respectively. The total output power of YSLD is ~4.5mW which is the highest ever reported power on this material system at room-temperature.
