TLDR
In this paper, a novel photonic crystal fiber (PCF) chemical sensor was designed where the cladding structure is made of a steering wheel-shaped large non-circular airhole.Abstract:
In this paper, we design a novel photonic crystal fiber (PCF) chemical sensor wherein the cladding structure is made of a steering-wheel (SW)-shaped large non-circular air-hole. In this PCF, we int...read more
