摘要： A distributed feedback semiconductor laser oscillating in a single mode and a method for manufacturing the same is disclosed. The distributed feedback semiconductor laser includes an active layer; a clad layer formed adjacent to the active layer; and diffraction gratings periodically formed in the clad layer and separated from each other by a predetermined distance. The diffraction gratings are formed of a nonconductor so that a current injected into the active layer is partially blocked and distribution of gain coefficient is varied. The nonconductor is an oxidized semiconductor material.

摘要： An electro-absorptive optical modulator module monolithic-integrated on a semiconductor substrate, which includes a distributed feedback laser having a grating for oscillating light and to output the oscillated light through a first end and a second end of the module. An electro-absorptive modulator modulates a first light output through the first end of the distributed feedback laser, and an optical detector provides detection of a second light output through the second end of the module. The optical detector is formed opposite to the second end of the distributed feedback laser on the semiconductor substrate. A first inner window permits attenuation of the intensity of the second light and electrically insulates the distributed feedback laser and the optical detector from each other, with the first inner window being arranged between the distributed feedback laser and the optical detector.
