Photonic crystal devices: some basics and selected topics

Abstract

This review article is concerned with basic aspects and some selected topics in photonic crystal (PhC) devices. It starts with a significantly historical aspect of basic principles for photonic crystals that it is hoped will help the reader to develop a critical appreciation of the research literature. It continues by describing topics such as PhC beamsplitters, slow‐light structures, micro‐/nanoresonators, coupled resonator optical waveguides (CROWs) and PhC‐based semiconductor lasers. Emphasis is placed on both the conceptual and the practical matters that need to be addressed in order to fulfill the tasks of designing and realizing devices that exploit photonic crystal principles. The review also addresses some of the problems encountered in the fabrication of photonic crystal devices using the planar technologies of integrated photonics, which are those that are most likely to be used in future commercial production.

Control of coupling in 1D photonic crystal coupled-cavity nano-wire structures via hole diameter and position variation

“…The periodic structure of photonic crystals (PhCs) controls the optical propagation through a dielectric medium [4,5] -and provides a potential platform for realization of compact photonic biosensors and photonic integrated circuits (PICs) [6,7] with the aim of achieving monolithic integration on a single chip. Silicon-on-insulator (SOI) is one of the typical material systems used, due to its high refractive index contrast.…”

Effect of fabrication tolerances on the performance of two-dimensional polymer photonic crystal channel drop filters: a theoretical investigation based on the finite element method

“…1,2 The wavelength of the defect modes in PhC slabs can be identified by tailoring both size and shape of defects. This allows one to design and fabricate microcavities covering a wide range of applications in the field of low-threshold lasers, 3 channel drop filters, [4][5][6] and chemical sensing.…”

Lorenz–Mie theory for 2D scattering and resonance calculations

“…These effectively 2D devices are of great practical interest since they can easily be integrated on photonic circuits. This allows the fabrication of innovative optical elements onto existing technological platforms, for instance silicon-on-insulator wafers [3,18] or plastic substrates [19].…”
