A method of laser-writing submicron pixels with tunable circular polarization and write-read-erase-reuse capability on BiSe/WSat room temperature, comprising the steps of applying a laser to the BiSe/WS, writing a submicron pixel, wherein the submicron pixel has a circular polarization, modifying the circular polarization, allowing the circular polarization to be tuned across a range of 39.9%, tuning photoluminescence intensity, and tuning photoluminescence peak position. A method of growing BiSe/WSas a nano-material or two-dimensional heterostructure for laser-writing submicron pixels with tunable circular polarization and write-read-erase-reuse capability on the BiSe/WSheterostructure at room temperature.
