Surface modes in air-core photonic band-gap fibers.
We present a detailed description of the role of surface modes in photonic band-gap fibers (PBGFs). A model is developed that connects the experimental observations of high losses in the middle of the transmission spectrum to the presence of surface modes supported at the core-cladding interface. Furthermore, a new PBGF design is proposed that avoids these surface modes and produces single-mode...
متن کاملSynthesis of Electromagnetic Modes in Photonic Band Gap Fibers
In this paper, we report on the successful synthesis of three individual modes, HE11 , TE01, and TE 02 for transmission in photonic band gap fibers at near infrared wavelengths. We measure the propagation losses of the HE,1 and TE0 1 modes both inside and outside the band gap of the fiber, and show that the TE0 1 is indeed the lowest loss mode, and is less lossy and has a much wider band gap th...
متن کاملHollow-Core Photonic Band Gap Fibers for Particle Acceleration
Photonic band gap (PBG) dielectric fibers with hollow cores are being studied both theoretically and experimentally for use as laser driven accelerator structures. The hollow core functions as both a longitudinal waveguide for the transverse-magnetic (TM) accelerating fields and a channel for the charged particles. The dielectric surrounding the core is permeated by a periodic array of smaller ...
متن کاملAngular photonic band gap
Materials and structures that strongly discriminate electromagnetic radiation based on one, or more of its properties (e.g. polarization, frequency) play an enabling role for a wide range of physical phenomena. For example, polarizers can selectively transmit light based on its polarization [1] over a wide range of frequencies; photonic crystals [2] (PhCs) can reflect light of certain frequenci...
متن کاملPhotonic band-gap structures
The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electronwave propagation in real crystals has proven to be a fruitful one. Initial efforts were motivated by the prospect of a photonic band gap, a frequency band in three-dimensional dielectric structures in which electromagnetic waves are forbidden irrespective of the propagation direction in sp...
