Photonic Crystal Fiber

Abstract

Reducing the complexity of opticalsystems emphasizes the need to increase the number of optical functions in as few modules as possible, making the system more compact and simple to operate. Optical functions such as light generation, frequency conversion, amplification, broadband transmission, wavelength filtering and interfacing to the outside environment typically needed separate, individual optical components to be chained together to comprise a system. However, with the advent of Photonic Crystal Fiber, many of these functions can be combined into multifunctional modules paving the way for simpler, turn‐key systems.

Optical Properties of the Self-Assembling Polymeric Colloidal Systems

“…In the last years, polymeric photonic crystals found application in optical devices [43][44][45] and sensors [46] or as templates for other interesting porous-media applications taking advantage of their optical properties, composition, or morphology [26,47,48].…”

“…Recently, the propagation mechanism of light inside 3D polymer colloidal crystals gained much interest, leading to an important progress in photonic applications such as microlasers, waveguides, or photonic crystal fibers [45].…”

Mimicking Natural Fibrous Structures of Opals by Means of a Microemulsion-Mediated Hydrothermal Method

“…Silicon-based fiber devices are the backbone of modern optoelectronic − and telecommunication , systems and are widely used for guiding and distributing light in optical arrangements . A novel type of optical fiber developed mainly during the past decade and pioneered by Russell and co-workers is the microstructured fiber, frequently called the photonic crystal fiber (PCF).…”

“…In general, the combination of a fibrous structure and photonic crystal proterties just with a semiconductor structure provides to the PCFs a series of unique properties impossible to achieve in classical silicon fibers. For example: PCFs maximize nonlinear interactions between laser light and low-density media such as gases; in PCFs small dielectric particles can be trapped, levitated, or propelled in a laser beam using the dipole forces exerted by light; and PCFs with extremely small solid glass cores and very high air-filling fractions not only display unusual chromatic dispersion but also yield very high optical intensities per unit power. ,, …”
