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…
Experimental demonstration of a high quality factor photonic crystal microcavity
Kartik Srinivasan, Paul E. Barclay, Oskar Painter +3
Sub-threshold measurements of a photonic crystal (PC) microcavity laser operating at 1.3 microns show a linewidth of 0.10 nm, corresponding to a quality factor Q ~ 1.3x10^4. The PC…
