Title: Distributed feedback semiconductor laser and hologram scanner using it
Inventor: ABE HIROAKI
IPC: H01S5/00
Filed: 1994-12-13
Abstract: PURPOSE: To provide a distributed feedback semiconductor laser which is difficult to produce crystal defects, and easy to make the oscillation wavelength coincide with the peak of the gain curve of semiconductor material. CONSTITUTION: A diffraction grating to be a resonator is obtained by forming a semiconductor epitaxial substrate having a substrate 12, a lower clad layer 13, an activated layer 14. an upper clad layer 15, and a contact layer 16, and forming regular recessions 20 from the contact layer 16 over to the clad layer 15. When the combination of the clad layer and the activated layer is InP-In GaAsP, it is suitable for the oscillation of a laser beam of an infrared wavelength band. In the case of InGaAlP-InGaP, it is suitable for the oscillation of a laser beam of a visible red band. Crystal defects are difficult to produce since there are no crystal-grown films on the diffraction grating.  It is possible to reduce threshold current, since the interval Λ of the recessions 20 can be set by adjusting it to the gain curve characteristic of an epitaxial substrate whose all layers are laminated.
