Abstract: A photonic device designed with an intermittent absorption profile along a waveguide. The absorption profile is divided into low-absorption and high-absorption segments that are distributed axially in order to decrease the maximum local temperature in the device. The distribution of low-absorption segments can be controlled through techniques such as proton implantation or selective-area quantum well intermixing. The lengths of low-absorption and high-absorption segments can be adjusted to optimize heat dissipation along the device length.

Abstract: A multiple phase wavelength locker employs an etalon with multiple steps, the steps providing optical cavities having different optical lengths for use with multiple photodetectors, such that a resonance position of each etalon step is offset by a fraction of a resonance period. The stepped etalon can be employed to track the exact wavelength of a laser in a wavelength division multiplexing (WDM) system.

Abstract: A compensating electrical signal is applied to one or more sections of a laser to over-compensate for chirp from an external modulator employed for intensity modulation. The chirp of the laser is adjustable by design or electrical control.
