waveguide structure for the IR multi-wavelength chain distributed feedback laser in the active core is made of a cascade stage

摘要

A chained distributed feedback laser with a novel waveguide is disclosed, the waveguide allows for the coupling of a laser beam between an active waveguide structure and a passive waveguide structure, improving device design and improved output efficiency. enable. A method of making such a device is also disclosed along with a method of use.
