Title:
WAVEGUIDE STRUCTURE FOR MID-IR MULTIWAVELENGTH CONCATENATED DISTRIBUTED-FEEDBACK LASER WITH AN ACTIVE CORE MADE OF CASCADED STAGES
Document Type and Number:
WIPO Patent Application WO/2013/142481
Kind Code:
A3
Abstract:
Concatenated distributed feedback lasers having novel waveguides are disclosed. The waveguides allow for coupling of the laser beam between active and passive waveguide structures and improved device design and output efficiency. Methods of making along with methods of using such devices are also disclosed.
