Numerical investigations of two-dimensional photonic crystal optical properties, design and analysis of photonic crystal based structures

Vasily Zabelin

Two-dimensional (2D) photonic crystals (PhCs) operating in the near-infrared wavelengths are promising candidates for novel integrated optics applications. In this work the optical properties of the Bloch modes in 2D photonic crystals have been investigate ...

Analysis of photonic crystals with defects using coupled-mode theory

Elyahou Kapon, Amos Andras Hardy

A mathematical approach is presented that is based on coupled-mode theory (CMT); it is extended to infinite perfect photonic structures and combined with the supercell method for analysis of infinite photonic crystals with introduced point (0D) and linear ...

Photonic crystal chips for optical interconnects and quantum information processing

Hatice Altug

We have recently demonstrated a number of functional photonic crystals devices and circuits, including an ultrafast, room-temperature, low threshold, nanocavity laser with the direct modulation speed approaching 1THz, an all-optical switch controlled with ...

Nanophotonic crystals with chiral elements by a hot embossing process in SU-8

Shenqi Xie, Yi-Chiang Sun

We report a novel nanoprocess to fabricate 2D metallic and non-metallic nanophotonic crystals on SU-8 using hot embossing combining with a UV-curing process. The fabricated photonic crystals were characterized by optical diffraction experiments. Theoretica ...

Nanofluidic tuning of photonic crystal circuits

Demetri Psaltis

By integrating soft-lithography-based nanofluidics with silicon nanophotonics, we demonstrate dynamic, liquid-based addressing and high Δn/n (∼0.1) refractive index modulation of individual features within photonic structures at subwavelength length scales ...

Low-threshold ultrafast surface-passivated photonic crystal nanocavity lasers

Hatice Altug

Efficiency and speed of photonic crystal lasers are improved by passivating InGaAs/GaAs membranes using (NH(4))S treatment. Lasers show five-fold reduction in nonradiative surface recombination rate, resulting in four-fold reduction in threshold and room-t ...

Optical mode control in VCSEL-based photonic crystal heterostructures

Lars Lundeberg

The field of photonic crystals is a rapidly developing branch of modern optics. Photonic crystals are believed to be the cornerstone for a wide range of new photonic devices controlling the confinement and propagation of light. These artificial structures ...

Tunable microcavities in planar photonic crystals

Hans Peter Herzig, Iwan Märki

Micro- and nano-optical structures offer the possibility to control light on a wavelength scale. This allows further miniaturization of integrated optical circuits. Planar photonic crystal waveguides and microcavities are considered basic building blocks f ...

Passive and active two-dimensional photonic crystal components

Photonic crystals are periodic dielectric structures having periodicity of the order of the wavelength. Consequently, they offer the ability to control the propagation of electromagnetic waves in a similar way as the periodic potential aspects the electron ...
