This paper presents an overview of our work on the design, fabrication, and integration of micro/nano-scale optical devices as applicable for all-optical generic and application-specific VLSI photonic integration. The micro/nano-optical devices are designed to perform the functions of collecting, storing, transporting, processing, switching, routing, and distributing optical signals on chips. The...
In this talk we will discuss issues related to technology for dense photonic integration based on silicon platform, and review two alternatives to achieve this goal within the diffraction limit; photonic nanowires and photonic crystal waveguides. We will also present examples of our demonstrators to illustrate the feasibility of photonic wires for device miniaturization and benefits offered by photonic...
Finite-difference time-domain (FDTD) simulation is employed to study Y- and T-junction photonic crystal (PC) components which incorporate defects along the waveguides. In particular, such components designed in silicon with hexagonal lattices of air cylinders are studied, and the FDTD method is used to optimise key design parameters. It is shown that the defects can allow control over power-splitting...
