Abstract
A QC laser comprises first and second optical confinement (i.e., cladding) regions, and an In-based, Group III-V compound, QC active region disposed between the confinement regions. At least the first confinement region and the active region having the shape of an elongated mesa. An i-type InP layer covers the sidewalls to provide efficient heat transport and effective low loss mode confinement. A metal layer makes ohmic contact with the top surface of the mesa and a rectifying contact with the i-InP layer.
