Nonlinear finite-difference time-domain method for the simulation of anisotropic, chi((2)), and chi((3)) optical effects
(Georgia Institute of Technology, 2006-01)
A two-dimensional (2-D) finite-difference timedomain (FDTD) code for the study of nonlinear optical phenomena, in which both the slowly varying and the rapidly varying components of the electromagnetic fields are considered, ...
Observation of large parity-change-induced dispersion in triangular-lattice photonic crystal waveguides using phase sensitive techniques
(Georgia Institute of Technology, 2006-02)
We experimentally studied W1 triangular-lattice photonic crystal waveguides (PCWs) fabricated on semiconductor-on-insulator substrates using phase-sensitive lock-in techniques. In addition to the improved signal-to-noise ...
Compact wavelength demultiplexing using focusing negative index photonic crystal superprisms
(Georgia Institute of Technology, 2006-03)
Here, we demonstrate a compact photonic crystal wavelength demultiplexing device based on a diffraction compensation scheme with two orders of magnitude performance improvement over the conventional superprism structures ...
