Title:
TUNABLE LASER WITH CASCADED FILTER AND COMB REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2016/112776
Kind Code:
A1
Abstract:
A laser (400) comprises a gain medium (405), and a mirror (407) coupled to the gain medium (405) and comprising a coupler (410) coupled to the gain medium (405), a phase section (413) coupled to the coupler (410), a bandpass filter (420) coupled to the phase section (413), and a comb reflector (CR) (453) coupled to the bandpass filter (420). A laser chip package comprises a substrate, and a laser (400) coupled to the substrate and comprising a filter (420) comprising a first interferometer (423) with a first transmittance, and a second interferometer (435) with a second transmittance, wherein the filter (420) is configured to provide a filter transmittance based on the first transmittance and the second transmittance, and a comb reflector (CR) (453) coupled to the filter (420) and comprising a ring with a circumference, and a refractive index, wherein the CR (453) is configured to provide a CR reflectivity based on the circumference and the refractive index.
