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…
Optical-fiber based measurement of an ultra-small volume high-Q photonic crystal microcavity
Kartik Srinivasan, Paul E. Barclay, Matthew Borselli +1
A two-dimensional photonic crystal semiconductor microcavity with a quality factor Q ~ 40,000 and a modal volume Veff ~ 0.9 cubic wavelengths is demonstrated. A micron-scale optica…
Probing the dispersive and spatial properties of planar photonic crystal waveguide modes via highly efficient coupling from optical fiber tapers
Paul E. Barclay, Kartik Srinivasan, Matthew Borselli +1
The demonstration of an optical fiber based probe for efficiently exciting the waveguide modes of high-index contrast planar photonic crystal (PC) slabs is presented. Utilizing the…
