Method for preparing a photonic crystal laser and a photonic crystal laser

Abstract

The invention provides a preparation method of a photonic crystal laser and a photonic crystal laser itself. The method includes: creating a two-dimensional periodic array of air holes on a semiconductor wafer to form a photonic crystal, and each primitive cell of the array contains one air hole; the photonic crystal is divided into a left domain and a right domain; shift the left domain to the left by the first preset distance; shift the right domain to the left by a second preset distance, or rotate the right domain by a preset angle along a point on the interface between the left domain and the right domain; truncate the right domain along the interface and keep the right part of right domain. This invention enables the creation of photonic crystal lasers with advantages such as broad spectral bandwidth, multiple wavelengths, low threshold, and high power.
