Dynamic beam distribution via beam splitter
We propose a dynamic beam splitter incorporating all-dielectric metasurface in an elastic substrate under external mechanical stimulus of stretching. The optical behavior at 720 nm wavelength shows that it can be changed from a pure optical-diode-like behavior to a dynamic beam. A beam splitter is a common device for dividing an incident beam into two separate beams. Their bulky size, right-angled output direction, and fixed splitting ratio greatly limit the design of optical arrangement and. This paper demonstrates the realization of an extraordinary beam splitter, exhibiting one-way beam splitting amplification. Such a dynamic beam splitter operates based on nonreciprocal and synchronized photonic transitions in obliquely illuminated space-time-modulated (STM) slabs which impart the. Beam splitters are an indispensable part of optical measurements and applications.
