  • Patent number: 10335978
    Abstract: A method of fabricating three-dimensional (3D) structures comprises forming a patterned area in a handle wafer, and bonding a mold wafer over the patterned area to produce one or more sealed cavities having a first pressure in the handle wafer. The mold wafer is heated past its softening point at a second pressure different from the first pressure to create a differential pressure across the mold wafer over the sealed cavities. The mold wafer is then cooled to harden the mold wafer into one or more 3D shapes over the sealed cavities. One or more materials are deposited on an outer surface of the mold wafer over the 3D shapes to form a structure layer having 3D structures that conform to the hardened 3D shapes of the mold wafer. The 3D structures are then bonded to a device wafer, and the handle wafer is removed to expose the 3D structures.

  • Publication number: 20180224299
    Abstract: A system for obtaining air data for a vehicle comprises a laser device that emits laser light pulses, and transmit optics that transmits the light pulses into an external air volume adjacent to the vehicle. The system also includes receive optics that collects scattered portions of the light pulses from the external air volume, and a whispering gallery mode (WGM) frequency discriminator that receives the scattered portions of the light pulses from the receive optics. The WGM frequency discriminator includes at least one WGM resonator that outputs a selected portion of the light pulses at one or more optical signal frequencies via tuning the WGM resonator other than by an electro-optic effect. An optical detector samples the selected portion of the light pulses from the WGM frequency discriminator, and converts the sampled light pulses to scalar values. A processing unit receives and records the scalar values from the optical detector.
