Tunable semiconductor laser to operate with a photonic crystal/resonator mirror has a resonator structure and a resonator final mirror

摘要

Divided into sections (1a,1b,1c), a resonator structure has an active layer (2) for generating beams and transversal/lateral wave ducts. Different length dimensions and grating structures (9a,9b) for them cause mode separations to differ from each other by 7 to 10 percent. Photonic crystals (6) are integrated as longitudinal and, if required, lateral restrictions on the resonator structure. An Independent claim is also included for a method for producing a semiconductor laser.
