A recent study conducted by a team of researchers has revealed that nonlinear exciton-polaritons can be generated in a single-layer of WS2. This is a remarkable discovery that could open up new avenues for the study of optoelectronic devices and photonic circuits. The study, published in the journal Nature Physics, shows that nonlinear exciton-polaritons can be generated in a single-layer of WS2 when illuminated with a low-intensity laser. This is an important breakthrough which could lead to the development of new types of optoelectronic devices and photonic circuits. The findings of the study could also pave the way for the exploration of new types of nonlinear optical materials with unprecedented properties.
