摘要： A spectrum analyzer includes an array of frequency-selective bulk acoustic wave (BAW) resonators each tuned to a predetermined different resonant frequency. The spectrum analyzer further includes a broadband BAW resonator that generates acoustic energy when connected to a signal source. An acoustic coupling transmits the acoustic energy generated by the broadband BAW resonator to the frequency-selective BAW resonators so that one of the frequency-selective BAW resonators will generate an electrical output signal if the acoustic energy transmitted from the broadband BAW resonator contains spectral components at its predetermined resonant frequency.

摘要： An apparatus for optically shifting the frequency of an input signal beam includes a first Raman medium that receives an input signal beam, a first pump beam, and a first reference beam to responsively generate an intermediate signal beam comprising a Raman sideband of the first Raman medium. A second Raman medium is optically coupled in series with the first Raman medium. The second Raman medium receives the intermediate signal beam, a second pump beam, and a second reference beam to responsively generate an output signal beam comprising a Raman sideband of the second Raman medium. The generated output signal represents the input signal that is shifted in frequency by a frequency shift that corresponds to the frequency difference between the first and second reference beams.

摘要： An optical isolator for coupling light from a first waveguide to a second waveguide is disclosed. The optical isolator utilizes a resonator coupled to the first and second optical waveguides. The resonator has a resonance at λ for light traveling from the first optical waveguide to the second optical waveguide; however, the resonator does not have a resonance at λ for light traveling from the second waveguide to the first waveguide. The resonator can use a layer of ferromagnetic material in an applied magnetic field. The magnetic field within the ferromagnetic material varies in strength and/or direction over the layer of ferromagnetic material. The magnetic field can be generated by an external magnetic field that varies over the layer of ferromagnetic material. Alternatively, the resonator can include a layer of ferromagnetic metal that overlies a portion of the layer of ferromagnetic material and a constant external magnetic field.

摘要： A motion sensor configured to control compensation for movement of an imaging device receiving light representative of a selected scene on an image plane. The motion sensor includes and array of photoelements and a controller. The array of photoelements is configured to acquire successive images of features of an environment within a field of view of the motion sensor; including a first image of features and a second image of features acquired at a time interval after the first image, the first and second images including common features. The controller is configured to receive and correlate the first and second images to detect movement of the imaging device about a first and a second axis during the time interval by detecting differences in locations of the common features relative to the array of photoelements, and to provide first and second compensation signals based on the correlation to control opto-mechanical adjustments to counter detected movement of the imaging device about the first and second axes so as to maintain a substantially fixed relationship between the selected scene and the imaging plane.
