Abstract

In the prospective of attaining highly negative dispersion, low confinement loss, normalized frequency a micro structured slotted dual-core PCF has been outlined. A four ring hexagonal solid core PCF have dual core that are slotted by four rectangular slots and other rings are filled with air. FEMSIM module of R-Soft software has been accessed to procure simulations. The upshot unfolds that at diameter d=1.5 µm, 1.65 µm and 1.75 µm, the and confinement loss as 0.000025, 0.000029, 0.000033, further it was also found that dispersion is highly negative and normalized frequency is also found to be low. Introduced PCF is applicable for sensing purpose and also for long haul transmission. This PCF is also used like optical sensor and in the security screening.
