Parallel Power Computation for Photonic Crystal Devices

Design of photonic crystal devices

The subject of this PhD thesis is the study of photonic crystal waveguides that incorporate discontinuities or structural fabrication-induced variations. For the numerical study of these devices the mode matching (MM) method is proposed. The comparison of the MM method with the couple mode theory (CMT) showed that the CMT can provide only a first approximation to the perturbation-induced scatte...

Photonic Materials and Devices

Our recent advances in solid-state optoelectronic materials and devices will be reviewed. In the area of glass optics, fabrication of novel microstructured and multi-core fibers and their use in realizing single mode lasers will be summarized. In organic and plastic optics, photorefractive polymers for 3D display applications and nonlinear optical polymers for high speed modulators in RF photon...

Design of a High-Bandwidth Y-Shaped Photonic Crystal Power Splitter for TE Modes

In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitt...

Theory of Photonic Crystal Structures and Concepts for Photonic-Crystal based Devices

Quantum photonic devices in single-crystal diamond

Nitrogen–vacancy centers in diamond have outstanding quantum optical properties that enable applications in information processing and sensing. As with most solid-state systems for quantum photonic applications, the great promise lies in the capability to embed them in an on-chip optical network. Here we present basic integrated devices composed of diamond micro-ring resonators coupled to waveg...
