  • Patent number: 11923101
    Abstract: An optical tweezer phonon laser system and method for modulating mechanical vibrations of an optically levitated mechanical oscillator to produce coherence is disclosed. A feedback loop is configured to simultaneously supply an electro-optic modulator with an amplification signal and a cooling signal representing an amplification force linear in the mechanical oscillator momentum and a cooling force nonlinear in the mechanical oscillator variable position and linear in the momentum, respectively controlling the intensity of a trap beam levitating the mechanical oscillator.

  • Publication number: 20230384489
    Abstract: A system includes a source configured to emit partially spatially coherent light and a metasurface located proximate to a light emitting surface of the source, where the metasurface is configured to modify at least one property of the emitted light. Modifiable properties include phase, amplitude, directionality, far field profile, and polarization. The metasurface may be passive or active. An active metasurface may be controlled using an input such as applied voltage, temperature, and mechanical force. The system may be configured to provide coherent illumination.
