The practical applications of these crystals in devices rely strongly on deterministic engineering of their spatially localized electromagnetic field distributions, which has remained challenging. This study demonstrates that polariton interference can be enhanced and tailored by patterning the vdW crystal {\\alpha}-MoO3 into mic","authors_text":"Fengsheng Sun, Huanjun Chen, Huizhen Liao, Joshua D.
