Abstract
A fiber-grating semiconductor laser with tunability is provided, which varies a output wavelength easily. The fiber-grating semiconductor laser with tunability is the hybrid integrated module on a substrate. It consists of a semiconductor laser as a gain medium and a Bragg-grating-written fiber held in a wavelength-tuning unit. (deletion) The wavelength-tuning unit can apply compression or elongation in the fiber grating for wavelength tunability.
