Abstract
In this paper, an embedded metal-wire nanograting was fabricated and used to construct a multifunctional optical device. The basic function of the nanograting is as a broadband polarizing beam splitter. On the top of the nanograting surface, a homogeneity cladding layer was deposited, and metal wires were deposited in the grating trench. This multifunctional optical device based on the artificial material is designed with a very simple structure, but with the functions of a variable optical attenuator, an optical switch, and a variable optical power splitter. The experimental result as a variable optical power splitter is presented.
