Abstract: PURPOSE:To improve wavelength measuring precision and simplify a device by using a Cerenkov radiation type secondary higher harmonic generating element. CONSTITUTION:The light L1 from a light source 3 is entered to the light waveguide pass 2 of a Cerenkov radiation type SHG element 1 through a collimator lens 4 and a condenser lens. Thus, a secondary higher harmonic is generated by the non-linear optical effect of the SHG element 1, and the secondary higher harmonic L2 is emitted with a Cerenkov radiating angle theta from the main surface of a non-linear optical material 11. The incident light or primary light is cut by a filter 7, and only the secondary higher harmonic L2 is passed through it and entered to a position sensor 8 consisting of CCD, whereby the incident position is detected. The Cerenkov radiating angle theta can be detected from this position, and the input wavelength depending on the radiating angle can be precisely measured.

Abstract: PURPOSE:To reduce retrogressive light from an outgoing end face or the like of a non-linear optical element facing a semiconductor laser while making the semiconductor laser always stably oscillate a fundamental wave laser light. CONSTITUTION:A semiconductor laser 1 and a non-linear type optical element 2 are butt-coupled so that the outgoing end face of the semiconductor laser and the incident end face of the non-linear type optical element may be adjacent.

Abstract: PURPOSE:To enhance the propagation efficiency of light in a waveguide and the coupling efficiency of a light source with the optical waveguide by forming the distribution in electric field intensity in the depth direction of a substrate by a propagation mode in an incident end part where a beam from the light source is made incident on deeper than other part. CONSTITUTION:This device is provided with the optical waveguide 1 propagating the beam in the electric field direction perpendicular to the main surface of the substrate 3, and is constituted so that the distribution 4, 5 in electric field intensity in the depth direction of the substrate 3 by the propagation mode of the optical waveguide 1 are formed deeper than other part in the incident end part where the beam from the light source is made incident on. Thus, the shape of the distribution 4, 5 in electric field intensity of a waveguide mode in the end surface of the optical waveguide 1 is brought close to the shape of the distribution 4, 5 in electric field intensity in the light emitting point of the light source, and the superposition integration of the distribution 4, 5 in electric field intensity of an incident beam in the incident end surface of the optical waveguide 1 with the distribution 4, 5 in electric field intensity of the waveguide mode propagating in the optical waveguide 1 is enhanced. Thus, the propagation efficiency of light in the waveguide 1 and the coupling efficiency of the light source with the optical waveguide 1 are enhanced.
