【 摘 要 】

We investigate a D-shaped photonic crystal fiber sensor with Molybdenum disulfide (MoS2) as a bio-recognition layer. The proposed sensor works based on the principle of surface plasmon resonance. Here, a thin layer of gold is deposited on the side polished flat surface of the PCF over which monolayer MoS2is deposited in order to enhance the sensitivity of the sensor. The proposed sensor exhibits the sensitivity of 2000 nm/RIU.
