Title:
面発光レーザ
Document Type and Number:
Japanese Patent JP4027393
Kind Code:
B2
Abstract:
There is provided a novel surface emitting laser structure unnecessary to have multilayer mirrors in both of upper and lower sides of an active layer. A surface emitting laser comprises a two-dimensional periodic structure which is comprised of an active material having a gain in a specific wavelength band of electromagnetic waves, and a reflecting mirror arranged apart by a predetermined distance so as to face the above-mentioned two-dimensional periodic structure, and these are comprised so as to make laser oscillation possible. At that time, the above-mentioned two-dimensional periodic structure is formed of a two-dimensional photonic crystal which is comprised of a dielectric, and a resonator is comprised of a reflecting mirror pair formed by combination with the above-mentioned reflecting mirror to make laser oscillation generated.
