Abstract: Chip technology for fabricating ultra-low-noise, high-stability optical devices for use in an optical atomic clock system. The proposed chip technology uses diamond material to form stabilized lasers, frequency references, and passive laser cavity structures. By utilizing the exceptional thermal conductivity of diamond and other optical and dielectric properties, a specific temperature range of operation is proposed that allows significant reduction of the total energy required to generate and maintain an ultra-stable laser. In each configuration, the diamond-based chip is cooled by a cryogenic cooler containing liquid nitrogen.

Abstract: A method includes receiving light at a light input of an electro-optic modulator device. The method includes directing the light via the light input into optical waveguides in an optical layer of an electro-optic modulator of the electro-optic modulator device. The method includes receiving a signal at an electric input of the electro-optic modulator device. The electric input is associated with an input impedance. The method includes providing the signal to an electrode structure of the electro-optic modulator. The electrode structure generates an electrical field based on the signal. The electric field modulates light in the optical waveguides to produce modulated light based on the signal. The electrode structure includes a constant impedance section associated with a second impedance less than the input impedance. The method also includes providing the modulated light based on the signal from the optical layer to one or more output optic fibers.

Abstract: A receiver and a transmitter are disclosed that are applicable to space, air or ground RF communication systems and are applicable to systems where one or more signals of multiple types and characteristics are present in any given beam such as a communication spot beam on a high-throughput satellite. The transmitter can include an optical frequency comb configured to generate a multitude of equidistantly spaced optical wavelengths; an electro-optic modulator that receives the multitude of equidistantly spaced optical wavelengths and a data signal and produce a modulated optical beam; an optical circulator that receives the modulated optical beam; an optical switch that switches the modulated optical beam to an output port of the optical switch terminated in one or more Fiber-Bragg gratings; a wavelength division multiplexer that receives individual wavelengths of the modulated optical beam that are time-delayed from the optical circulator; and a plurality of antenna elements.
