Optimization and Comparison of Circular and Elliptical PCF for Generation of Slow Light in Optical Communication Using 2d FDTD Method


Nilambar Muduli*, J.S.N Achary, Priya Sahu

Effect on generation of a tunable slow rate light can be estimated by fabricating circular and elliptical PCFs. Choosing the background material to be As2Se3 Chalcogenide glass for their investigation. In addition, we have also measured the maximum allowed pump power for undistorted output pulse, Brillouin gain and time delay using same PCFs structure. It reports that, Brillouin.gain is found to be 87.2 dB/m for circular PCF(C-PCF), 90 dB/m for elliptical PCF (E-PCF) and time delay reaches to 138.64ns C-PCF, 142ns for EPCF.
The above results seem to be measured using 1m long PCFs pumped with 100mW for both C-PCF and E-PCF. The simulating result of E-PCF is much more intensity for potential application in optical buffering, data synchronization, optical memories and signal processing etc over C-PCF.
