【発明の名称】量子細線レーザ及びその製造方法
Document Type and Number:
Japanese Patent JP2799372
Kind Code:
B2
Abstract:
A quantum wire laser comprises a first multilayer structure which is formed on a substrate and includes at least one first quantum well layer sandwiched by barrier layers, a second multi-layer structure which is formed on a laminated cross-section of the first multi-layer structure and is obtained by successively laminating a first barrier layer having a band gap larger than that of the first quantum well layer, a second quantum well layer having a band gap nearly equal to that of the first quantum well layer, and a second barrier layer having a band gap larger than those of the first and second quantum well layers, wherein a region for confining electrons is disposed in at least one of regions in the vicinity of the first quantum well layer and the second quantum well layer.
