Abstract

Presented are the first short wavelength (4.4-4.7 μm) QC-DFB lasers, targeted to the detection Co. They employ strained heterostructure material (InGaAs/AlInAs on InP, grown by molecular beam epitaxy) with global strain compensation to provide the large band offset needed for high performance at short wavelengths.
