Patent JP-H04280490-A (JP)
Title: Semiconductor laser equipment
Inventor: TOMITA AKIHISA
IPC: H01S5/00
Filed: 1991-03-08
Abstract: PURPOSE:To provide a semiconductor laser capable of modulating up to few Gb/s or higher frequencies where the influence of the carrier injection time is eliminated. CONSTITUTION:A diffraction lattice is formed on a part of an n-type layer 13 to compose a resonator of a cleavage plane and the diffraction grating. An active layer 15 on the diffraction grating is removed to form a waveguide layer 16 consisting of a semiconductor whose band gap is larger than the energy of oscillation light by 20-100meV. The active layer 15 and the waveguide layer 16 are electrically isolated to provide an electrode 22 for injection on the active layer 15 and an electrode for modulation 20 on the part of the waveguide layer 16. Current in a normal direction is applied to the active layer 15 and reverse direction current is applied to the waveguide layer 16. The light-absorption-loss on the waveguide layer 16 changes in accordance with the modulation signal due to the Franz-Keldysh effect, with photon lifetime in laser changing. The modulation of the photon lifetime is not affected by the injection time of the carrier, thereby allowing high-speed modulation.
