Abstract

PCFs (Photonic Crystal Fibers) with 'T' -shaped core have been proposed in this paper. 'T' -shaped core PCF structures have been analyzed using two different background materials: silica and lead silicate. A total of 360 0 rotation at an interval of 90 0 has been introduced in the design of PCF structures. PCF structures A, B, C and D with rotation of 0 0 , 90 0 , 180 0 and 270 0 have silica as wafer. Similarly PCF structures E, F, G and H with similar rotation have lead silicate as background material. 'F', 'G', and 'H' have reported birefringence of the order of 10 -2 . Besides, other PCF structures report birefringence of the order of 10 -3 . Ultra low confinement loss has been observed in all the investigated PCF structures. Moreover, splice loss observed by the structure is very low. Large mode area has been shown by all the designed PCF structures. Numerical investigations shows structures 'D', 'F', 'G' and 'H' to have anomalous dispersion. PCF structures

There are many ways to design PCFs to meet such a goal.…”
