Abstract: PROBLEM TO BE SOLVED: To provide an optical element with an integrated light deflector with which a light direction is deflected without requiring a complicated external driving circuit. SOLUTION: A manual waveguide having the light deflector integrated therewith is equipped with cladding regions 301, 304, an optical waveguide core 302 and the light deflector 303. A propagation direction of light waveguided to the optical waveguide core 302 is varied in passing of the light through the light deflector 303. The light deflector 303 is formed by patterning a part of the upper cladding layer on the upper side of a specified region of the optical waveguide core 302 in a predetermined shape and deflects the propagation direction of the advancing light by modifying the refractive index of the core 302 on the lower side of the predetermined shape in accordance with a current or an electric field applied to the light deflector 303.

Abstract: PURPOSE: An apparatus for generating multi-wavelength light is provided to have high single mode stability and high yield according to transmission spectra, reduce light loss, improve element reliability, and increase the coupling efficiency of lights. CONSTITUTION: A high reflective coating film(110) is formed on a cross-section of a gain portion(120). The high reflective coating film can be composed of mirror elements having high reflection or a metal or dielectric thin film coating surface. The gain portion generates multi-wavelength lights. Each channel included in the gain portion includes a gain waveguide for providing gains to generated light. A reflecting portion(130) again reflects the lights entering from the gain waveguide to the gain portion. A multiplexing portion(140) multiplexes single mode lights generated in each channel of a distributed bragg reflector laser.

Abstract: A long cavity single mode laser diode is provided to improve the stability of axis directional single mode and yield of device by amplifying and transmitting a beam having a specific wavelength by adjusting a current of an optical amplifier placed in a ring waveguide. A long cavity single mode laser diode includes a first optical amplifier, an array waveguide diffraction grating, a wavelength selecting SOA array, and a ring waveguide. The first optical amplifier amplifies beam and outputs the beam. The array waveguide diffraction grating separates the beam into a plurality of wavelengths according to an arrayed waveguide. The wavelength selecting SOA array amplifies the light of each separated wavelength. The ring waveguide is connected to the first optical amplifier to form a feedback loop. The ring waveguide includes a second optical amplifier inside the feedback loop.
