  • Patent number: 10534137
    Abstract: Unlike most MEMS device configurations which simply switch between two positions in many optical devices the state of a MEMS mirror is important in all transition positions. It may determine the characteristics of an optical delay line system and by that an optical coherence tomography system in one application and in another the number of wavelength channels and the dynamic wavelength switching capabilities in the other. The role of the MEMS is essential and it is responsible for altering the paths of the different wavelengths in either device. It would be beneficial to improve the performance of such MEMS and thereby the performance of the optical components and optical systems they form part of. The inventors have established improvements to the design and implementation of such MEMS mirrors as well as optical waveguide technologies to in-plane optical processing as well as the mid infrared for optical spectroscopy.

  • Patent number: 10474101
    Abstract: A method and system for recycling signals in a leaky mode device for a holographic display or other application. A leaky mode device comprises at least a first transducer, a substrate, and a second transducer. The first transducer may be configured to receive an input signal from a signal arbiter, which forwards to the first transducer as an input signal either a new input signal or a recycled input signal (or some combination of the two). The first transducer converts the received input signal to a SAW (surface acoustic wave) and transmits the SAW through the substrate to the second transducer, which converts the received SAW to an output signal, and forwards the output signal to an amplifier, which amplifies the output signal (now a “recycled” signal) and forwards to the signal arbiter. This system facilitates persistence for points in a holographic display without the need for continually rewriting to leaky mode devices.

  • Patent number: 10466421
    Abstract: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to provide multiple independent multi-gigabit channels on one optical fiber. To meet demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost monolithic optical circuit technologies and microelectromechanical systems (MEMS) have become increasingly important. However, further integration via microoptoelectromechanical systems (MOEMS) of monolithically integrated optical waveguides upon a MEMS provide further integration opportunities and functionality options. Such MOEMS may include MOEMS mirrors and optical waveguides capable of deflection under electronic control. In contrast to MEMS devices where the MEMS is simply used to switch between two positions the state of MOEMS becomes important in all transition positions.
