  • High-coherence semiconductor light sources
    Patent number: 9933554
    Abstract: A laser resonator includes an active material, which amplifies light associated with an optical gain of the resonator, and passive materials disposed in proximity with the active material. The resonator oscillates over one or more optical modes, each of which corresponds to a particular spatial energy distribution and resonant frequency. Based on a characteristic of the passive materials, for the particular spatial energy distribution corresponding to at least one of the optical modes, a preponderant portion of optical energy is distributed apart from the active material. The passive materials may include a low loss material, which stores the preponderant optical energy portion distributed apart from the active material, and a buffer material disposed between the low loss material and the active material, which controls a ratio of the optical energy stored in the low loss material to a portion of the optical energy in the active material.
    Type: Grant
    Filed: February 5, 2016
    Date of Patent: April 3, 2018
    Assignees: CALIFORNIA INSTITUTE OF TECHNOLOGY, TELARIS INC.
