Analysis of ring-structured Bragg fibres for single TE mode guidance.
نویسندگان
چکیده
Ring-structured Bragg fibres that support a single TE-polarisation mode are investigated. The fibre designs consist of a hollow core and rings of holes concentric with the core, which form the low-index layers of the Bragg reflector in the cladding. The effects of varying the air fraction in each ring of holes on the transmission properties of the fibres are analysed and an approximate model based on homogenisation is explored. Surface modes and transitions thereof are also discussed.

تحلیل مدهای TE و TM در فیبربراگ بلورفوتونی با استفاده از روش ماتریس انتقال
In this article, we considered the field analysis in photonic crystal Bragg fibers. We apply the method of transmission matrix to calculater the dispersion curves, the longitudinal wave number over wave number versus incident wavelength, and the field distributions of TE and TM modes in the Bragg fiber. Our analysis shows that the field of guided modes is confined in the core and can exist onl...
متن کاملNew Possibilities with Microstructured Polymer Optical Fibres
Progress on microstructured polymer optical fibres (MPOFs), a new class of polymer fibres that were developed last year, will be presented, including single-mode MPOF, highly birefringent MPOF, twin-core MPOF, graded-index MPOF, ring-structured MPOF and photonic band gap MPOF, the latter case being where light can be guided in an air core.
متن کاملBasic properties of ring-index optical fibres
This work analyses theoretically, technologically and practically a class of low-loss single-mode optical fibers with ring refractive index profile. The fibers are considered for long distance signal transmission as well as photonic signal processing. Trunk transmission, ring index fibers have shifted and flattened dispersion characteristics and much larger effective area as compared with stand...
متن کاملModels for guidance in kagome-structured hollow-core photonic crystal fibres.
We demonstrate by numerical simulation that the general features of the loss spectrum of photonic crystal fibres (PCF) with a kagome structure can be explained by simple models consisting of thin concentric hexagons or rings of glass in air. These easily analysed models provide increased understanding of the mechanism of guidance in kagome PCF, and suggest ways in which the high-loss resonances...
متن کاملSurface-emitting circular DFB, disk- and ring- Bragg resonator lasers with chirped gratings: a unified theory and comparative study.
We have developed a theory that unifies the analysis of the modal properties of surface-emitting chirped circular grating lasers. This theory is based on solving the resonance conditions which involve two types of reflectivities of chirped circular gratings. This approach is shown to be in agreement with previous derivations which use the characteristic equations. Utilizing this unified analysi...
