Title: Photonic crystal laser
Inventor: SUSA NOBUHIKO
IPC: H01S5/10
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce the threshold energy and the threshold gain of a defect type photonic crystal laser. SOLUTION: The photonic crystal has materials with different refractive index which are periodically arranged in lattice form. Parts of lattice points comprising cylindrical-shaped air holes (vacancy) 2 corresponding to the materials with low refractive index are removed for forming lattice defects. Gain medium 3 of the laser is arranged in the position of the lattice defects for forming a photonic crystal laser. The cylindrical holes 2 are made in a dielectric material such as silicon corresponding to the material with higher refractive index of the photonic crystal by etching or the like. Since current injection excitation or light excitation is efficiently aroused only in parts of a resonator by arranging the gain medium in it, the threshold energy can be reduced. Also, by optimizing the radius and the refractive index of the gain medium, the threshold gain can be reduced.
