Optical loss and lasing characteristics of high-quality-factor AlGaAs microdisk resonators with embedded quantum dots
Kartik Srinivasan, Matthew Borselli, Thomas J. Johnson +4
Optical characterization of AlGaAs microdisk resonant cavities with a quantum dot active region is presented. Direct passive measurement of the optical loss within AlGaAs microdisk…
Nonlinear absorption and dispersion in fiber-taper-coupled silicon photonic crystal microresonators
Paul E. Barclay, Kartik Srinivasan, Oskar Painter
A technique is demonstrated which efficiently transfers light between a tapered standard single-mode optical fiber and a high-Q, ultra-small mode volume, silicon photonic crystal r…
Design of two-dimensional photonic crystal defect states for quantum cascade laser resonators
Kartik Srinivasan, Oskar Painter
Current quantum cascade lasers based upon conduction band electron transitions are predominantly TM (electrical field normal to the epitaxial direction) polarized. Here we present…
Rayleigh scattering, mode coupling, and optical loss in silicon microdisks
Matthew Borselli, Kartik Srinivasan, Paul E. Barclay +1
High refractive index contrast optical microdisk resonators fabricated from silicon-on-insulator wafers are studied using an external silica fiber taper waveguide as a wafer-scale…
Optical fiber coupling to planar photonic crystal microcavities
Paul E. Barclay, Kartik Srinivasan, Oskar Painter
A technique is demonstrated which efficiently transfers light between a tapered standard single-mode optical fiber and a resonant mode of a high-Q photonic crystal cavity with mode…
Feasibility of detecting single atoms using photonic bandgap cavities
Benjamin Lev, Kartik Srinivasan, Paul Barclay +2
We propose an atom-cavity chip that combines laser cooling and trapping of neutral atoms with magnetic microtraps and waveguides to deliver a cold atom to the mode of a fiber taper…
