Abstract
In one example, a DFB laser includes a substrate, an active region, and a grating. The active region is formed above the substrate and is designed to emit light having a gain peak wavelength. The grating is formed above the active region and is designed to provide optical feedback for light having a lasing peak wavelength. The gain peak wavelength is longer than the lasing peak wavelength and a difference between the gain peak wavelength and the lasing peak wavelength at room temperature is between 10 nm and 50 nm.
