| Summary: | To realize active light control with a compact structure, a nanoscale optical switch-based plasmonic demultiplexer is proposed. The device is designed according to the metal-Kerr nonlinear material-metal waveguide with multiple resonant cavities, providing the capability of active optical regulation for dual wavelengths: Signals of <inline-formula><tex-math notation="LaTeX">$\text{1310}$</tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$\text{1550 nm}$</tex-math></inline-formula> can be guided into either output with high directional extinction ratios larger than 30 dB controlled by another pump light of <inline-formula> <tex-math notation="LaTeX">${\text{730 nm}}$</tex-math></inline-formula> with low power. Considering its light control capability and compact configuration, it is believed that the proposed demultiplexer can be adopted in the future logic plasmonic circuits. |
