Absorbing boundary conditions for low group velocity electromagnetic waves in photonic crystals
(Georgia Institute of Technology, 2011-03)
We present an efficient method for the absorption of slow group velocity electromagnetic waves in photonic crystal waveguides (PCWs). We show that adiabatically matching the low group velocity waves to high group velocity ...
Preconditioned superprism-based photonic crystal demultiplexers: analysis and design
(Georgia Institute of Technology, 2006-11)
We present the analysis and design of a new type of photonic crystal (PC) demultiplexers (i.e., preconditioned demultiplexer), in which the simultaneous existence of the superprism effect and the negative effective index ...
