摘要： PROBLEM TO BE SOLVED: To provide a waveguide type filter which has a simple configuration and has a lower temperature-dependency of a center wavelength than conventional one by easy processing, and to provide a semiconductor laser element using the same. SOLUTION: The waveguide type filter wherein a wavelength is not varied contrary to the conventional common sense can be achieved by using a grating assist coupler which is conventionally used in order to widen a wavelength variable region, as a base and by giving a fixed relation to a structure of two cores and a clad layer. Since the temperature-dependency of the center wavelength is determined by the difference between temperature-dependencies of equivalent refractive indexes, any of filters having positive, zero, and negative temperature-dependencies of the center wavelength respectively can be achieved regardless of signs of temperature-dependencies of equivalent refractive indexes by controlling the relation between the temperature-dependency of an equivalent refractive index in a fundamental mode and that in a first-order mode.

摘要： PROBLEM TO BE SOLVED: To suppress gain fluctuation due to input light intensity without allowing oscillation light to mix into a guide wave direction of signal light and also to adjust the gain of the signal light during use. SOLUTION: An input waveguide 402 and an output waveguide 404 are constituted of a single-mode waveguide made of a gain medium including InGaAsP as a core. In addition, multi-mode waveguides 403a and 403b are constituted of a multi-mode waveguide made of a gain medium including InGaAsP as a core. Highly reflective films 409 and 410 are oppositely provided on both sides of the multi-mode waveguide 403. While laser oscillation is caused in the waveguide 403 in the direction orthogonal to the guide wave direction of the input signal light 411, the input signal light 411 is conveyed into the waveguide 403. Thus, the input signal light 411 is amplified, and also current can be fed independently into the gain media of the input waveguide 402 and the multi-mode waveguides 403a and 403b, respectively.
