摘要： Provided are a laser diode generating passive mode locking that does not contain non-linear sector of an SA, and a method of creating an optical pulse using the same diode. The laser diode includes a DFB sector serving as a reflector and a gain sector. The gain sector is connected to the DFB sector and includes an as-cleaved facet formed at the end of the gain sector. When a current less than a threshold current is applied to the DFB sector to allow the DFB sector to operate as a reflector, passive mode locking occurs swiftly and therefore a sector of the SA is not required, which makes manufacturing simple. Also, it is possible to effectively extend a frequency variable region compared to using of the SA.

摘要： The present invention relates to high power semiconductor laser device and method for fabricating the same utilizing ion implanting process, by which a beam steering phenomenon of an optical output due to filaments is eliminated. This elimination is achieved by a periodically varying gain given for a resonator of the semiconductor laser device. That is, this invention changes a gain distribution which causes the generation of filaments in the resonator into different distribution. According to the present invention, there is formed an insulation layer through ion implantation to an active layer to adjust current density implanted to the active layer, thereby eliminating non-uniform distribution of the light along the longitudinal direction of the resonator.

摘要： Disclosed is a method for fabricating a planar buried heterostructure laser diode, comprising the steps of sequentially forming a first clad layer, an undoped active layer and a second clad layer on a substrate so as to complete a first crystal growth; forming a patterned mask layer on the second clad layer; non-selectively etching the second clad layer, the active layer, the first clad layer and the substrate using the mask layer as an etching mask; selectively etching the substrate and the first and second layers; sequentially forming a first and second current blocking layers on a structure formed by the selective etching step so as to complete a second crystal growth; sequentially forming a third clad layer and an ohmic contact layer thereon after removal of the mask layer so as to complete a third crystal growth; and forming a first electrode on a rear surface of the substrate and forming a second electrode on a surface of the third clad layer. By the method, a leakage current induced in an interface between the active layer and the first current blocking layer provided therein can be reduced in proportion to a distance between the active layer and the second current blocking layer formed on the first current blocking layer, and therefore performance of the laser diode can be enhanced.
