IPC: H01L33/06
Filed: 2008-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a wavelength variable filter and a semiconductor light-emitting device which are easy to control, using a simple constitution.  <P>SOLUTION: This wavelength variable filter 10 is provided with: the first substrate 12; an optical waveguide core layer 20 provided on the first substrate; a diffraction grating 24, positioned along the direction substantially orthogonal to the optical axis direction of the optical waveguide core layer, and coupled optically with the optical waveguide core layer; and the first electrode E2 for supplying a wavelength regulating signal, in one part 25a along an optical axis direction of the diffraction grating. The length of the one part along the optical axis direction of the diffraction grating is shorter than the other portion 25b, along the optical axis direction of the diffraction grating. Phase shift effect is obtained, since the refractive index in the one part of the diffraction grating varies, by supplying the wavelength-regulating signal from the electrode. Consequently, transmission wavelength is changed readily, within the stop band of the diffraction grating, by regulating the amount supplied from the first electrode.  <P>COPYRIGHT: (C)2009,JPO&INPIT
