We design a ten-fold photonic quasi-crystal fiber using finite element method. Further, we explore various optical characteristics and exploit them for realizing a biosensor. We achieve a maximum refractive index sensitivity of 29000 nm/RIU and a resolution of 3.4 × 10-6 RIU a sensing range of 1.47-1.48. © 2015 IEEE.

Designing a refractive index based biosensor using a photonic quasi-crystal fiber

2015 Workshop on Recent Advances in Photonics (WRAP)

We propose a fiber stretcher for stretching the high-energy ultrashort pulses which require high dispersion and large mode area to secure high stretching ratio and for ensuring distortionless pulses. In this line, we suggest a novel design of photonic quasi-crystal fiber (PQF) to achieve the desired high normal group velocity dispersion (GVD) of 1000 ps2/km at 1.06 μm and inner core effective mode area as 35 μm2. These unique properties have been exploited to achieve a high stretching ratio (&gt;105) as well as less nonlinearity, which, in turn, results in a distortionless fiber stretcher for an Yb-doped high-energy ultrafast fiber laser system based on chirped pulse amplification. © 2006 IEEE.
