Problems solved by technology

However, it is difficult for microdisk lasers and microring lasers to obtain directional output. In order to obtain directional output, we have developed an equilateral triangular microcavity laser with an output waveguide (Y.Z.Huang, etc. Room-temperature continuously-wave electrically injected InP / GaInAsPequilateral-triangle -resonator lasers.IEEE Photon.Technol.Lett.19, pp.963-965(2007)) and square microcavity lasers (Y.Z.Huang, etc.Directionalemission InP / GaInAsP square-resonator microlasers, Opt.Lett.33, (2008 ))

Abstract

The invention discloses a regular polygon microcavity bistable semiconductor laser which is formed by etching a slab waveguide and comprises a regular polygon resonant cavity and an output waveguide, wherein the output waveguide is connected or coupled with the regular polygon resonant cavity. By utilizing the invention, because the relation between the quality factor and the coupling efficiency of different symmetry modes in the regular polygon microcavity is different along with the change of the waveguide, the width of the output waveguide is controlled to enable the different symmetry modes to have the same threshold gain and different coupling efficiency, thus the output bistable characteristic of the regular polygon microcavity laser can be realized.

Description

technical field [0001] The present invention relates to the technical field of semiconductor lasers, in particular to a regular polygonal microcavity bistable semiconductor laser, and more particularly, the present invention relates to a regular polygonal microcavity laser with an output waveguide, wherein modes of different symmetries compete and their output waveguide The different output coupling efficiencies make this regular polygonal microcavity laser have output bistable characteristics. Background technique [0002] Bistable semiconductor lasers fabricated by planar technology have important applications in photonic integration technology as optical storage and optical trigger. With the progress and innovation of modern information technology, photon integration and optoelectronic integration have developed greatly. High efficiency, low power and miniaturization are the current development directions of optoelectronics, but it is difficult for most traditional bista...
