Conventional implementations only cover the C band, while broadband, metamaterial-based devices require sub-100nm feature sizes. We propose a design based on dual-etch silicon subwavelength structures that achieves a 170 nm bandwidth with deep-UV compatible feature sizes. https://hdl.handle.net/10630/20512 Metamateriales Silicio sobre aislante Metamaterial engineered C+L band 90º hybrid with 150 nm feature size
