Title: Multiwavelength array laser
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/00
Filed: 1988-07-28
Abstract: PURPOSE:To simply obtain a multiwavelength array laser of two or more wavelengths by a method wherein, while a width of the upper part of a trapezoid is changed, a thickness of a growth film grown on it is changed. CONSTITUTION:At least an active layer 4 and layers 2, 3 existing at the lower part of the active layer 4 have at least two or more trapezoid-shaped protruding parts stretched in a direction of a resonator; widths of upper faces of the protruding parts have individually different structures. Since, in these structures, the widths of the upper parts of trapezoids as ridges are different from each other, a film thickness and a composition of a growth film grown on them are changed by using a crystal growth method having dependence on a plane orientation. Thereby, a multiwavelength array laser of two or more wavelengths can be obtained simply.
