Abstract: Various examples of a closed-loop optical gyroscope are disclosed. The closed-loop optical gyroscope includes a broadband light source configured to generate broadband optical signal(s). The broadband optical signal(s) propagate in an optical resonator and are coupled in and out of the optical resonator by optical couplers. A phase modulator applies phase modulation to the optical signal(s) based on a sawtooth modulation signal. The optical signal(s) repropagate in the optical resonator in a different direction. The optical signal(s) are then received and analyzed to determine parameter(s) of the phase modulator. One or more processors configure the phase modulator based on the determined parameter(s).

Abstract: Systems, apparatuses, and methods for implementing a periodic receiver clock data recovery scheme with dynamic data edge paths are disclosed. An IQ link calibration scheme performs a non-destructive data and edge path switch to determine an IQ offset without disturbing the data. A data path and an edge path pass through multiple stages of deserializers to widen the data path, with the deserializers clocked by clock divided versions of the original data and edge clocks. To initiate a calibration routine, the edge clock is aligned with the data clock, and then data and edge paths are swapped at a common point in a slower clock domain. The data path is then calibrated while the edge path carries the data signal. After the data path is calibrated, the edge and data paths are swapped back to the original configuration.

Abstract: A method of growing single crystal diamond assisted by polycrystalline diamond growth to enhance dimensions and quality of the single crystal diamond includes thermally mating a diamond seed on a top surface of a substrate holder providing a growth surface for a combination of single crystal diamond and polycrystalline diamond. A predetermined temperature difference between the diamond seed and the substrate holder during processing along with the plasma process conditions causes a single crystal diamond growth rate to be different from a polycrystalline growth rate by a predetermined amount. Process gasses are introduced, and a plasma is formed to grow both single crystal diamond and polycrystalline diamond on the growth surface so that the polycrystalline diamond grown adjacent to the single crystal diamond shields side surfaces of the growing single crystal diamond, thereby improving growth quality across the growing single crystal diamond.
