Abstract

We present an ultra-broadband, high-performance and fabrication-tolerant Y–junction enhanced with subwavelength grating metamaterials. Exhaustive measurements over a 1420–1680 nm bandwidth show fundamental mode excess loss under 0.3 dB considering a minimum-feature-size of 50 nm and below 0.5 dB for a 100 nm resolution scenario. Subwavelength Y–junctions with artificially induced errors of ±10 nm further demonstrate the fabrication-tolerant response of our design. Moreover, our proposed splitter exhibits first-order transverse electric mode excess loss lower than 1.5 dB within a 170 nm bandwidth (1420–1590 nm) in both 50 nm and 100 nm resolution scenarios.
