Abstract
A semiconductor distributed Bragg reflector laser configured for single longitudinal mode operation, having an optical waveguide comprising an optical gain section, a first reflector being a first distributed Bragg reflector (DBR) section comprising a grating configured to produce a reflection spectrum having one or more first reflective peaks, and a second reflector, wherein the first DBR section is configured to compensate for thermal chirp that is induced inhomogeneously along the length of the DBR section, in use.

A semiconductor distributed Bragg reflector laser configured for single longitudinal mode operation, having an optical waveguide comprising
- an optical gain section,
- a first reflector being a first distributed Bragg reflector (DBR) section comprising a grating configured to produce a reflection spectrum having a comb of first reflective peaks in an untuned state, and
- a second reflector,
- wherein the first DBR section is configured to compensate for thermal chirp that is induced inhomogeneously along the length of the first DBR section, in use.
