Patent ID: 8299858

Claim:
A device comprising: a solid-state atomic clock to generate a clock frequency signal, the solid-state atomic clock comprising: a solid-state atomic resonator module including a solid state atomic resonator formed by a solid-state material including an optical cavity having color centers, which are capable of exhibiting hyperfine transition, wherein the solid-state atomic resonator module is configured to receive an input frequency signal, which is based on said clock frequency signal, wherein the solid-state atomic resonator module is configured to generate a frequency error signal proportional to a difference between the input frequency signal and a hyperfine resonance frequency of said color centers, and wherein the solid state-atomic resonator module comprises a light source configured to generate light for illuminating said solid-state atomic resonator and a photo detector to generate the frequency error signal based on detected photo-luminescence of said color centers; a feedback circuit configured to generate an error-correction signal based on the frequency error signal provided by said solid-state atomic resonator module; a controlled oscillator configured to generate said clock frequency signal based on said error-correction signal; and a frequency multiplier configured to generate the input frequency signal to said solid-state atomic resonator module by multiplying a frequency of said clock frequency signal.
