Abstract

See full text

A light source has a resonant laser cavity with an optical grating and a waveguide that has a longitudinal axis. A portion of the longitudinal axis extends through the optical grating and serves as a grating axis. The laser cavity is configured to generate a laser signal that exits the laser cavity through the optical grating. The optical grating includes multiple perturbation structures that each causes a perturbation in an effective refractive index of the waveguide. The perturbation structures are staggered on the waveguide such that the perturbation structures that are adjacent to one another in a longitudinal direction are spaced apart in a transverse direction. The longitudinal direction is a direction parallel to the grating axis and the transverse direction is a direction transverse to the longitudinal direction.
