Design and Fabrication of Photonic Crystals for Small-Diameter Cryogenic Microring Lasers
Abstract
The University of New Mexico, a Carnegie-designated Research 1 University and a Hispanic-Serving Minority Institution, proposes a ba sic research on Design and Fabrication of Photonic Crystals for Small-Diameter Cryogenic Microring Lasers. The proposed research wil l focus on design and fabrication of 2-dimensional photonic crystals, initially for waveguides and Fabry-Perot lasers, and by Year 3 for small-diameter ring lasers. Modeling of two-dimensional photonic-crystal slabs will be performed using finite-difference time-d omain tools FullWAVE, distributed by RSoft-Synopsys, and OptiFDTD, distributed by Optiwave Systems, Inc. The MIT Photonic-Bands (MPB ) package will be used for computing the band structures (dispersion relations) and electromagnetic modes of periodic dielectric str uctures. The scattering-matrix numerical method will also be used to calculate the optical transmission properties and guided modes in two-dimensional photonic-crystal slabs of finite thickness. Photonic-crystal slabs, waveguides, Fabry-Perot lasers, and microring lasers operating at 1.55-m wavelength will be designed, fabricated, and characterized. The photonic-crystal ring lasers will be de signed and fabricated in two versions as whistle-geometry ring lasers and as ring lasers without the injecting waveguide. CW elect rical and optical characterization of the photonic crystal devices will be performed over a temperature range from 4 K to 350 K. Cry ogenic testing will be performed using an Integrated Cryogenic Electronics Testbed (ICE-T), manufactured by HYPRES, Inc. and customi zed for research on optoelectronic components. In particular, the testbed is the first of its kind that contains fiberoptic input an d output connections for cryogenic testing of optoelectronic devices.Approved for Public Release
