Title: Semiconductor laser element
Inventor: MATSUI YASUSHI
IPC: G02F1/025
Filed: 1984-10-16
Abstract: PURPOSE:To modulate an output from laser beams without changing injecting currents, and to obtain oscillating beams at a stable mode by electrically controlling a degree in which laser beams are coupled with an optical waveguide section adjacently arranged to a semiconductor laser section. CONSTITUTION:An InGaAsP optical waveguide layer 12, N<+>-InP 13, an InGaAsP active layer 21 and a P<+>-InP clad 14 are superposed on an N<+>-InP substrate 11, a P<+>-InP loading section is formed, and ohmic electrodes 16, 17 are attached. The active layer 21 and the clad layer 14 are buried to P-InP 19 and N-InP 20. Currents are injected from the electrode 16, beams emitted from the active layer 21 are laser-oscillated while crossing the waveguide layer 12, and there is a laser output even under the loading section 15 by distribution coupling. When constant currents are flowed through a laser section and the refractive index of a waveguide is changed by an electro-optic effect by utilizing a P-N junction under the loading section 15, coupling with the laser section varies, and an optical output from the laser section largely alters, thus acquiring oscillating beams at a mode more stable than normal direct modulation.
