Abstract
In accordance with one embodiment of the present disclosure, a DBR laser diode is provided where the wavelength selective grating of the laser diode is characterized by an aperiodically shifted grating phase φ and a Bragg wavelength λ. The aperiodically shifted grating phase φ is substantially symmetric or substantially π-shifted symmetric relative to a midpoint Cor shifted midpoint C* of the DBR section. The phase φ of the wavelength selective grating is characterized by aperiodic phase jumps of magnitude φand segment lengths lThe phase jumps of the wavelength selective grating are arranged substantially symmetrically about a midpoint Cor shifted midpoint C* of the DBR section along the optical axis of the DBR laser diode. At least two phase jumps reside on each side of the midpoint Cor shifted midpoint C* of the DBR section.
