| 英文摘要 | PURPOSE:To restrain the Hall burning of the title laser by a method wherein the total shift amount by the total of the phase shift amount of light in a waveguide and by the phase shift amount of equivalent light due to the phase of a periodic structure is other than an integral multiple of pi and the confinement factor of light in the waveguide is made different along the axial direction of a resonator by the cyclic structure. CONSTITUTION:A diffraction grating 2 is formed on an n-InP substrate At this time, a part whose phase is displaced by pi of the period of the diffraction grating 2, i.e., a phase shifter 3, is formed. This is intended to dislocate the phase shift amount of equivalent light by pi/2. A guide layer 4, a clad layer 6 and an ohmic layer 7 are crystal-grown on the diffraction grating 2. Then, a light waveguide 8 is formed in such a way that the width in the center of a resonator is at W2 and that the width at the end of the resonator is at W The light waveguide layer 8 is composed of the guide layer 4 and an active layer 5. At this time, the W2 and the W1 are designed in such a way that the total value of the equivalent shift amount in a waveguide region is at an integral multiple of pi. |
