Design, fabrication, and integration of micro/nano-scale photonic crystal devices and plasmonic devices for VLSI photonic integration application

We present on the design, fabrication and integration of micro/nano-scale photonic crystal devices and plasmonic optical devices for VLSI photonic integration application. Using photonic crystals, we design and fabricate nanoscale directional couplers, multimode interference devices, power splitters, wavelength splitters, triplexers, filters, and develop their integration and interconnection schemes and technology. Using plasmonic structures, we design and fabricate horizontal directional couplers, vertical directional couplers, and chirped grating plasmonic structures to generate subwavelength lightwaves to be focused onto nano-potonic devices and modules. We examine scientific and technological issues concerning the miniaturization, interconnection, and integration of these nano-scale photonic devices for applications toward functional VLSI integrated circuits and systems.
