英文摘要 | PURPOSE:To enable to control the oscillating wavelength of a laser beam without consuming electric power by a method wherein a quantum well construction is furnished to an optical waveguide on a Bragg reflection mirror, and a reverse directional electric field to P-N junction of a semiconductor substrate is applied in the laminating direction of the construction thereof. CONSTITUTION:An active layer 4 (act as a waveguide together with a waveguide layer 3) is made to have a quantum well construction consisting of InGaAsP layers 4a, 4b of two kinds having different compositions. The semiconductor laser element thereof radiates a laser beam from the quantum well active layer 4 under a P-side electrode 10 according to injection of a current from the P-side electrode 10 and an N-side electrode 12, the active layer 4 thereof and the waveguide layer 3 act as the waveguide, and oscillating wave length is decided as usual according to an optical resonator constructed by a Bragg reflection according to a grating 7 and a reflection according to a cleavage plane 13, while the quantum well construction is contained in the waveguide thereof on the grating 7, and oscillating wave length can be controlled by applying a voltage being reverse to the N-side electrode 12 to a control electrode 11, and changing thereby the index of refraction thereof. |
