  1. HIGH EFFICIENCY EDGE COUPLER, NOVEL NONLINEAR OPTICAL POLYMERS WITH LARGE KERR-COEFFICIENT AND AUTOMATIC LAYOUT GENERATION IN SILICON PHOTONICS

    Niu, Ben

    … To achieve this goal, loss mechanisms of basic inverse taper couplers are analyzed and experimentally verified. Then a cantilever-encapsulated inverse taper is demonstrated to further lower coupling loss compared to basic inverse tapers. Nonetheless, both couplers are designed to couple with …

    Tjioe, FideliaMassachusetts Institute of Technology2008

    … the fabrication uncertainties. Together with an inverse taper structure patterned in the waveguide end, the coupling loss was much reduced from 7.5dB (direct butt-coupling), to less than IdB. Besides, optical solder increases the reliability of device, as it prevents moisture and dust from …

  4. Efficient Light Coupling Techniques for Integrated Photonics

    Dewanjee, Arnab2017

    … I propose and demonstrate a compact bilayer inverse taper edge-coupler with enhanced fiber-to-chip coupling efficiencies for both TE and TM polarizations of commercial Si photonic circuitry. The current commercial practice of CMOS-photonics integration is limited to separate fabrication of …

  5. Large grain Ge growth on amorphous substrates for CMOS back-end-of-line integration of active optoelectronic devices

    Pearson, Brian (Brian Sung-Il)Massachusetts Institute of Technology2012

    … evanescent coupling between two overlapping inversely tapered waveguides, which ensure efficient coupling due to optical impedance matching. These couplers are designed to exhibit coupling efficiencies in excess of 98.4%, equivalent to a 0.07 dB coupling loss. The technique of evanescent …
