IPC: H01L33/00
Filed: 2004-01-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a laser oscillator having small threshold current, which operates properly at high temperatures.  <P>SOLUTION: A laser structure (100), that operates at a wavelength of 1.3μm in a high temperature, and its manufacturing method are provided. This laser structure has an InAsP quantum well layer. The quantum well layer (32) is sandwiched in between a first barrier layer (33) and a second barrier layer (34). The barrier layers (33) and (34) have a band gap energy higher than that of the quantum well layer (32). Further, each of the barrier layers (33) and (34) includes Ga<SB>x</SB>(AlIn)<SB>1-x</SB>P(x=0). This substance has a band gap energy larger than those of conventional barrier layer substances, such as InGaP. Therefore, discontinuity of the conduction band becomes large, and high-temperature performance is improved, without increasing the threshold current of the laser structure (100).  <P>COPYRIGHT: (C)2004,JPO&NCIPI
