  • Harmonic optical oscillator
    Patent number: 4961119
    Abstract: The Harmonic Optical Oscillator is a solid state clock on a microchip. Two solid state lasers of nearly identical frequency transmit beams into an optical waveguide. The two beams interfere with each other causing a modulation of the light amplitude in the waveguide. A light detector picks up the harmonic beat. Accuracy of at least 1/2 second a year (approximately 200 times better than today's quartz microchips) is expected.
