Phase change materials combined with silicon photonics are emerging as a promising platform to realize miniature photonic devices. We study the basic optical properties of a subwavelength-dimension silicon ridge waveguide with a 20-nm-thick Ge2Sb2Te5 (GST) top-clad layer. Numerical simulations show that the effective index of the Si-GST hybrid waveguide varies significantly when the G... https://unitedssports.shop/product-category/bike-accessories-bike-carriers/
