Broadband angular momentum cascade via a multifocal graphene vortex generator
文献摘要：
Light beams carrying orbital angular momentum[OAM]have inspired various advanced applications,and such abundant practical applications in turn demand complex generation and manipulation of optical vortices.Here,we propose a multi-focal graphene vortex generator,which can produce broadband angular momentum cascade containing continuous integer non-diffracting vortex modes.Our device naturally embodies a continuous spiral slit vortex generator and a zone plate,which enables the generation of high-quality continuous vortex modes with deep depths of foci.Meanwhile,the generated vortex modes can be simultaneously tuned through incident wavelength and position of the focal plane.The elegant struc-ture of the device largely improves the design efficiency and can be fabricated by laser nanofabrication in a single step.Moreover,the outstanding property of graphene may enable new possibilities in enormous practical applications,even in some harsh environments,such as aerospace.
