A custom-tailored, compact laser diode has been developed by integrating multiple wavelength emitters into a single device. Capable of emitting broadband wavelengths on demand, the device is smaller than a penny and works at room temperature. It can also emit light at frequencies within +/- 30 percent of the laser central frequency, which has never before been demonstrated in a single-laser diode.
