Abstract
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 then coated onto a SPF to serve as an optical polarisation state modulator based on the thermo-optic effect. The rotation of the polarised signal light is controlled using a pump laser. Throughout the pump power range of 514.5 mW, the polarisation state of the polarised signal light has rotated ∼70°, with a minor ellipticity fluctuation of <6°. The proposed experiment is carried out on the basis of the photon-modulate-photon principle and achieved all-optical modulation in a fibre laser system.
