Tunable Multi-Channels Bandpass InGaAsP Plasmonic Filter Using Coupled Arrow Shape Cavities

A new design for a tunable multi-channel plasmonic bandpass filter was numerically investigated using the two-dimensional finite element method (2D-FEM). The proposed consists of metal-insulator-metal waveguide (MIM-WG) and double-sided arrow-shaped cavities. Silver (Ag) non-linear optical medium (InGaAsP) are used in designed filter. InGaAsP fills bus refractive index is sensitive to incident light intensity, therefore resonance wavelengths can be controlled. Utilizing different intensities (such as 1017 v2/m2 2 × v2/m2) on InGaAsP, tuned over range from 600 nm 1200 nm. with confinement area 0.5 μm2 wavelength division multiplexing (WDM), photonic systems, coloring filters, sensing, 5G+ communication.
