OPTICAL COMMUNICATIONS LASER INCLUDING A RESONATOR FILTER Abstract A structure of first and second grating sections separated by a phase- shift section serves as a narrow-band resonator filter. Such structure may be optically coupled to a semiconductor laser cavity, and the resulting assembly can serve as a tunable narrow-linewidth laser, e.g., in wavelength-multiplexed and coherent-lightwave communications systems.
