Thermal tuning of silicon-based one-dimensional photonic bandgap structures
Thermal tuning of silicon-based one-dimensional photonic bandgap microcavities is demonstrated. Thermally induced spectral shifts are caused by both the host silicon matrix and the optically active material infiltrated inside the photonic bandgap structures. The active material leads to the dominant thermal tuning contribution but the effect of the silicon matrix cannot be neglected. The intera...
متن کاملTunable photonic bandgap structures for optical interconnects
As continued progress towards faster, low power consuming microelectronic devices becomes increasing difficult due to the scaling challenges of electrical interconnects, it becomes even more critical to explore alternative technologies. Tunable porous silicon photonic bandgap structures are viable building blocks for optical interconnects, which present a possible long term solution to the inte...
متن کاملTwo-stage design method for realization of photonic bandgap structures with desired symmetries by interference lithography.
Interference lithography for the fabrication of photonic crystals is considered. A two-stage design method for realization of photonic bandgap structures with desired symmetries is developed. An optimal photonic crystal with a large bandgap is searched by adjusting some parameters while keeping some basic symmetry of the unit cell unchanged. A nonlinear programming method is then used to find t...

متن کاملSimulation of Metallic Photonic Bandgap Structures for Accelerator Applications
Use of microwave photonic bandgap (PBG) structures is a promising approach to improving the performance of rf accelerator structures in terms of better control of wakefields. We have developed the Photonic Band Gap Structure Simulation (PBGSS) code to study bulk properties of electromagnetic TE and TM wave propagation in two-dimensional (2D) PBG structures. The eigenmodes are calculated and glo...
متن کاملModeling of realistic cladding structures for air-core photonic bandgap fibers.
Cladding structures of photonic bandgap fibers often have airholes of noncircular shape, and, typically, close-to-hexagonal airholes with curved corners are observed. We study photonic bandgaps in such structures by aid of a two-parameter representation of the size and curvature. For the fundamental bandgap we find that the bandgap edges (the intersections with the air line) shift toward shorte...
