MULTIWAVELENGTH QUANTUM CASCADE LASER VIA GROWTH OF DIFFERENT ACTIVE AND PASSIVE CORES |
摘要 |
Disclosed is a method of forming a laser source capable of producing mid-IR laser radiation comprises growing a first core structure on a substrate, etching away the first core structure in one or more locations, and growing a second core structure on the substrate. At least one of the core structures comprises a quantum cascade gain medium emitting at a frequency within the range from 3-14 μm. Also disclosed is a laser source capable of producing mid-IR laser radiation comprising a quantum-cascade core positioned on a substrate for emitting within the range from 3-14 μm and a second core on the substrate positioned in-plane relative to the first core. The second core is one of a) a passive waveguide core b) a second quantum-cascade core and c) a semiconductor active core region. |
