Title: Uniaxial mode semiconductor laser
Inventor: FUJITA SADAO
IPC: H01S5/026
Filed: 1988-05-19
Abstract: PURPOSE:To assure stable uniaxial mode oscillation without causing oscillation of a TM mode even with anti-reflecting coating by forming a metal film on part of an optical waveguide including an active layer in the vicinity of the wavelength. CONSTITUTION:After a first order diffraction grating 12 including a phase shift region 10 is formed on an n type InP board 13, on which there are successively grown a guide layer 14, an active layer 1, a cladding layer 2, and a cap layer 3. In a mode filter region 9 for restricting a TM mode, the cap layer 3 and part of the cladding layer 2 are etched a and after a SiO2 film 4 is formed on the region 9, a first electrode 5 is attached to the region 9. The region further has an anti-reflecting coating film 8 on both ends. In the mode filter region 9, since the electrode 5 is located in the close vicinity of the active layer 1, the TM mode with an electric component perpendicular to the electrode 5 among modes propagating in the optical waveguide 7 is attenuated. Further, since a TE mode is parallel to the electrode 5, it can propagate through the optical waveguide 7 substantially without any attenuation. Thus, the TE mode has very high gain and hence an optical output 11 assures stable uniaxial TE mode oscillation.

Title: Air bubble detection sensor
Inventor: NOMURA MASANORI
IPC: G01V8/12
Filed: 1984-06-15
Abstract: PURPOSE:To certainly perform the detection of air bubbles, by holding a light transmissive pipe between a light emitting element and a light receiving element and using a concave lens as the lens in the side of the light emitting element. CONSTITUTION:A light emitting element 12, of which the light emitting surface is made concave so as to be closely contacted with a pipe 2, and a light receiving element 13, of which the light receiving surface is formed into a concave one (may be not necessarily a concave surface) so as to be closely contacted with the pipe 2, are arranged in opposed relationship and pressed to the pipe 2 by proper force. When there is no liquid in the pipe 2, the light emitting from the light emitting element 12 is refracted to the direction separated from the light receiving element 13 except the part in the vicinity of the center line and does not reach the light receiving element 13. Next, when the liquid is present in the pipe 2, the liquid in the pipe functions as a convex lens and, therefore, the light emitting from the light emitting element 12 is almost incident to the light receiving element 13. As a result, the large difference can be generated in the intensity of light incident to the light receiving element by the presence or absence of the liquid and the presence or absence of the liquid or the detection of air bubbles can be performed certainly.
