Abstract: A clock generator includes a hermetically sealed cavity and clock generation circuitry. A dipolar molecule that exhibits a quantum rotational state transition at a fixed frequency is disposed in the cavity. The clock generation circuitry is configured to generate an output clock signal based on the fixed frequency of the dipolar molecule. The clock generation circuitry includes a detector circuit, a multiplier, and reference oscillator control circuitry. The detector circuit is coupled to the cavity, and is configured to generate a detection signal representative of an amplitude of a signal at an output of the cavity. The multiplier is coupled to the detector circuit, and is configured to multiply the detection signal with a mixing signal to produce a derivative of the detection signal. The reference oscillator control circuitry is configured to set a frequency of a reference oscillator based on the derivative of the detection signal.

Abstract: A clock apparatus includes: (a) a gas cell, including a continuous path cavity including a sealed interior for providing a signal waveguide; (b) an apparatus for providing an electromagnetic wave to travel along the continuous path cavity and for circulating around the continuous path cavity back toward and past a point of entry of the electromagnetic wave in the continuous path cavity; (c) a dipolar gas inside the sealed interior of the cavity; and (d) receiving apparatus for detecting an amount of energy in the electromagnetic wave, wherein the amount of energy is responsive to an amount of absorption of the electromagnetic wave as the electromagnetic wave passes through the dipolar gas.

Abstract: A micromechanical system (MEMS) resonator includes a base substrate. A piezoelectric layer has a first electrode attached to a first surface of the piezoelectric layer and a second electrode attached to a second surface of the piezoelectric layer opposite the first electrode. The first electrode is bounded by a perimeter edge. A patterned acoustic mirror is formed on a top surface of the first electrode opposite the piezoelectric layer, such that the patterned acoustic mirror covers a border strip of the top surface of the first electrode at the perimeter edge and does not cover an active portion of the top surface of the first electrode.
