Title: Photonic crystal laser, method of manufacturing photonic crystal laser, surface emitting laser array, light transmission system, and writing system
Inventor: ITO AKIHIRO
IPC: H01S5/183
Filed: 2005-06-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a photonic crystal laser which has a photonic crystal period structure where refractive indexes are two-dimensionally, periodically located near an active layer emitting by injection of carriers and resonates with the photonic crystal to surface-emit; a method of manufacturing the photonic crystal; a surface-emitting laser array; a light transmission system; and a writing system.  <P>SOLUTION: Because almost all the carriers pass through positions apart from holes of a low refractive index due to an effect of a current passage limiting layer which is composed of a high resistance area and conductive area located near the two-dimensional photonic crystal structure provided with a low-refractive index in a semiconductor layer, the proportion of the carriers reached a side wall to the carrier passing through the two-dimensional photonic crystal structure becomes small, thereby, the non-emitting recombination on the side wall of the hole of low refractive index is reduced. By preventing the non-emitting recombination, the leakage of current is inhibited, and the laser light can be resonated with a low threshold current.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
