An international team of researchers has developed a method of fabricating high-performance lenses in monolayer two-dimensional transitional metal dichalcogenide (TMDC) material using a femtosecond laser. The lens has a subwavelength resolution and a focusing efficiency of 31%, which marks a step closer to ultimately thin optical devices for use in nano-optics and on-chip photonic applications.
The team, led by Baohua Jia of the Swinburne University of Technology, Qiaoliang Bao formerly of Monash University, and Chengwei Qiu of the National University of Singapore, discovered that it is possible to generate nanoparticles by using a femtosecond laser beam to interact with the monolayer TMDC material, which is significantly different…READ MORE
