    摘要： A nano-optomechanical transducer provides ultrabroadband coherent optomechanical transduction based on Mach-wave emission that uses enhanced photon-phonon coupling efficiencies by low impedance effective phononic medium, both electrostriction and radiation pressure to boost and tailor optomechanical forces, and highly dispersive electromagnetic modes that amplify both electrostriction and radiation pressure. The optomechanical transducer provides a large operating bandwidth and high efficiency while simultaneously having a small size and minimal power consumption, enabling a host of transformative phonon and signal processing capabilities. These capabilities include optomechanical transduction via pulsed phonon emission and up-conversion, broadband stimulated phonon emission and amplification, picosecond pulsed phonon lasers, broadband phononic modulators, and ultrahigh bandwidth true time delay and signal processing technologies.

    摘要： A frequency selective infrared (IR) photodetector having a predetermined frequency band. The exemplary frequency selective photodetector includes: a dielectric IR absorber having a first surface and a second surface substantially parallel to the first surface; an electrode electrically coupled to the first surface of the dielectric IR absorber; and a frequency selective surface plasmonic (FSSP) structure formed on the second surface of the dielectric IR absorber. The FSSP structure is designed to selectively transmit radiation in the predetermined frequency band that is incident on the FSSP structure substantially independent of the angle of incidence of the incident radiation on the FSSP structure.

    摘要： In an embodiment, light from a single mode light source may be deflected into a low index contrast (LIC) waveguide in an opto-electronic integrated circuit (OEIC) (or “opto-electronic chip”) by a 45 degree mirror. The mirror may be formed by polishing an edge of the die at a 45 degree angle and coating the polished edge with a metal layer. Light coupled into the LIC waveguide may then be transferred from the LIC waveguide to a high index contrast (HIC) waveguide by evanescent coupling.

    摘要： In an embodiment of the invention, an optical coupler couples light unidirectionally from integrated circuit package to an integrated circuit die. The package has a large waveguide with a waveguide core that has a low index of refraction. The die has a set of very small waveguide cores that have a high index of refraction relative to the index of refraction of the large waveguide core on the package. The waveguide cores with high index of refraction attract light from the waveguide core with the low index of refraction. No light is coupled back into the large waveguide core. Also, the optical mode of the large waveguide on the package is smaller than a subset of waveguide cores on the die. Thus, light is coupled from the package to the die without the waveguide cores having to be tightly aligned with each other.

    摘要： A pair of phase shift photolithography masks and a process for deriving them is described. In one embodiment, the invention includes deriving a complex electric field estimate for an intended pattern to be produced by phase shift photolithography masks, optimizing the complex electric field estimates, generating a first phase shift mask using the real part of the complex electric field estimates, and generating a second phase shift mask using the imaginary part of the complex electric field estimates.
