OPTICAL SCANNER INTEGRATED WITH SUBSTRATE METHOD OF MAKING AND METHOD OF USING THE SAME

摘要

An optical scanner includes a substrate, and a tunable laser on the substrate, wherein the tunable laser is configured to emit light, and to sweep a wavelength of the emitted light through a waveband. The optical scanner further includes a grating over a top surface of the substrate, the grating configured to diffract light emitted from the tunable laser, and an angled reflective surface configured to reflect the diffracted light from the grating. The optical scanner further includes a refractive element configured to receive the reflected light from the angled reflective surface. The refractive element is configured to focus the reflected light in a first direction and to diverge the reflected light in a second direction perpendicular to the first direction.
