| 英文摘要 | PURPOSE:To solve the problem of wavelength dependency of an optical integrated device composed of elements greatly dependent on an associated wavelength such as a semiconductor laser, an optical waveguide, a thin film waveguide lens, and a grating by disposing on a waveguide an electrode capable of wavelength control by electrical control on an extension of the semiconductor laser optical waveguide. CONSTITUTION:The title optical integrated circuit comprises a semiconductor laser 3 including means of longitudinal single mode oscillation, and an electrode disposed on an extension of an optical waveguide part of the semiconductor laser 3, the electrode being capable of wavelength control by electrical control. The semiconductor laser 3 having the function of the wavelength control and other optical thin film function elements 4-6, 6' are integrated. For example, laser light, which is emitted from the AlGaAs semiconductor laser part 3 formed on a GaAs substrate 1 in a monolithic form, propagates through a three-layered dielectric waveguide 2, and is radiated and focused externally of the waveguide at a focusing grating coupler 5, and further the light reflected on a disk medium penetrates the focusing grating coupler 5, and is branched at a grating beam splitter and received by optical detectors 6, 6'. |
