Implementation of on-chip multi-channel focusing wavelength demultiplexing with regularized digital metamaterials
Jie Huang, Junbo Yang, Dingbo Chen +7
Adiabatic waveguide taper and on-chip wavelength demultiplexer are the key components of photonic integrated circuits. However, these two kinds of devices which designed by traditi…

All-optical switch and logic gates based on all-dielectric hybrid silicon-Ge2Sb2Te5 metamaterials
Zhaojian Zhang, Junbo Yang, Wei Bai +6
We numerically propose an all-dielectric hybrid metamaterial (MM) to realize all-optical switch and logic gates in shortwave infrared (SWIR) band. Such MM consists of one silicon r…

Chipscale plasmonic modulators and switches based on metal-insulator-metal waveguides with Ge2Sb2Te5
Zhaojian Zhang, Junbo Yang, Wei Bai +7
We introduce phase-change material Ge2Sb2Te5 (GST) into metal-insulator-metal (MIM) waveguide systems to realize chipscale plasmonic modulators and switches in the telecommunicatio…
