Abstract: The present disclosure discloses a method and apparatus for generating an optical frequency comb. The specific generation method comprises: receiving a pump laser that matches a thermally stable state of a nonlinear optical resonant cavity and causing the pump laser to oscillate in the nonlinear optical resonant cavity, such that a Brillouin gain corresponding to the pump laser coincides with a target longitudinal mode in the nonlinear optical resonant cavity; continuously generating a Brillouin laser at the target longitudinal mode in the case that a pump power of the pump laser exceeds a threshold for generating the Brillouin laser; and generating an optical frequency comb by using the Brillouin laser through a Kerr nonlinear four-wave mixing process. According to the technical solution of the present disclosure, the nonlinear optical resonant cavity with the Brillouin gain can generate an optical frequency comb in its thermally stable region.

Abstract: An electro-hydraulic actuator includes a deformable shell defining an enclosed internal cavity and containing a liquid dielectric, first and second electrodes on first and second sides, respectively, of the enclosed internal cavity.

Abstract: A serpentine delay-line waveguide feeding an array of grating couplers can be fabricated in a silicon photonic chip, or tile, with the grating couplers emitting light at an angle that varies with wavelength and delay between the couplers imparted by the waveguide. The beam-steering tile can be used to transmit or receive light from a scene. The tile can be arrayed with one or more other tiles for bistatic radar-lidar operation. A tile in the array may transmit probe and frequency-shifted reference beams, while another tile may receive a return at a heterodyne frequency giving a range to the scene. The pitch of the serpentine delay line may be different for transmitting and receiving tiles to suppress returns from unwanted directions. Pairs of phase-cohered tiles may illuminate a spot in the scene with fringe patterns, producing oscillating returns that can be processed to form a high-resolution sub-image by Fourier synthesis.

Abstract: A direct line-of-sight (DLOS) radio frequency (RF) signal component and a reflected RF signal component of an RF carrier signal are received from a transmitter. The reflected component is reflected from a point on the surface of the earth. The DLOS component is converted to a digital DLOS intermediate frequency (IF) signal and the reflected component that is converted to a digital reflected IF signal. Modeled reference signal parameters are generated using the digital DLOS IF signal and known locations of the one or more antennas, the transmitter, and the point. A reference signal is generated based on the modeled reference signal parameters and feedback of a previously estimated phase correction (??). The reference signal is correlated with the digital reflected IF signal to produce in-phase and quadrature-phase correlation results. Estimated carrier-to-noise ratio (C/N0) and ?? values are calculated for the digital reflected IF signal from the correlation results.
