In this work, all-optical polarisation state modulation using a tungsten disulfide (WS2) coated side-polished fibre (SPF) as modulator is experimentally demonstrated. A bulk layer WS2 is exfoliated into a few-layer WS2 thin film using liquid phase exfoliation technique. The few-layer WS2 film is the...
