Coherent Polaritons in WSe₂-Monolayer-Sandwiched Au-Nanodisk-on-Mirror Structures.

ABSTRACT: Owing to their direct bandgap and spin-valley locking in the visible to near-infrared region, transition metal dichalcogenide monolayers have emerged as promising candidates for next-generation atomically thin optoelectronics. The locking of the electron spin to different valleys offers a valley degree of freedom for information encoding. Nevertheless, the ability to address valley coherence is an important precondition for achieving the quantum manipulation of the valley index. Current access and control of coherent valley information typically relies on the use of high-quality distributed Bragg reflectors and extreme conditions involving an operating temperature of ∼4 K and an applied magnetic field up to 9 T, which is far from the demands of quantum optics and practical optoelectronic a
