Abstract
An oscillator system includes a laser source; a high-Q electro-optical oscillator to generate a high-Q electro-optical oscillator signals having oscillator frequencies; and an environment-insensitive resonator including ENZ metamaterials. The resonator receives a laser from the laser source and generate a feedback signal to lock the oscillator to reduce a phase/frequency noise in the oscillator. An optical system also includes a high-Q electro-optical oscillator to generate a high-Q electro-optical oscillator signal having oscillator frequencies; an environment insensitive signal delay waveguide having an EMNZ metamaterial such that the signal delay waveguide delays the high-Q electro-optical oscillator signal and generates a delayed signal; and a phase-lock circuit to receive the delayed signal from the signal delay waveguide and provide an electrical feedback signal to the oscillator.
