AbstractA 1 × 2 plasmonic demultiplexer with a rectangular metal-insulator-metal (MIM) waveguide comprising one input port and two output ports has been proposed. The proposed demultiplexer is based on the principle of interference of surface plasmon polariton waves. By placing the output port at the designed position along the rectangular MIM waveguide, the desired wavelength can be extracted from the mixture of the wavelengths. Results were simulated using finite element method (FEM) technique and plot of field and its intensity were obtained for both the wavelengths. The results agree with the proposed theory. Power transmission of more than 80% at the desired port with a suppression of more than 90% at the undesired port is obtained for both the wavelengths. A low crosstalk of less than −11.06 dB with a low insertion loss of less than 14.32 dB are measured. It is shown that the wavelength selectivity of the plasmonic demultiplexer is further dependent on the width of the MIM waveguide as well as the materials chosen. The design can be further extended to a 1×N demultiplexer by appropriate selection of position of the output ports.

The four polarisation method is adopted for measurement of molecular orientation in dielectric nanolayers of metal-insulator-metal (MIM) metamaterials composed of gold nanodisks on polyimide and gold films. Hyperspectral mapping at the chemical finger printing spectral range of 4–20 μμm was carried out for MIM patterns of 1–2.5 μμm period (sub-wavelength). Overlay images taken at 0,π4,π2,3π4 orientation angles and subsequent baseline compensation are shown to be critically important for the interpretation of chemical mapping results and reduction of spurious artefacts. Light field enhancement in the 60-nm-thick polyimide (I in MIM) was responsible for strong absorption at the characteristic polyimide bands. Strong absorbance A at narrow IR bands can be used as a thermal emitter (emittance E=1−R), where R is the reflectance and A=1−R−T, where for optically thick samples the transmittance is T=0.

A tunable demultiplexer with three output channels infiltrated by liquid crystal (LC) is presented, which is based on a metal-insulator-metal (MIM) waveguide. The operating frequencies of the three output channels can be tuned simultaneously at will by changing the external bias electric field applied to the LC. By analyzing the Fabry-Pérot (FP) resonance modes of the finite-length MIM waveguide both theoretically and numerically, the locations of the three channels are delicately determined to achieve the best demultiplexing effects. Terahertz (THz) signals input from the main channel can be demultiplexed by channels 1, 2 and 3 at 0.7135 THz, 1.068 THz and 1.429 THz, respectively. By applying an external electric field to alter the tilt angle of the infiltrating LC material, the operating frequencies of channels 1, 2 and 3 can be relatively shifted up to 12.3%, 9.6% and 9.7%, respectively. The designed demultiplexer can not only provide a flexible means to demultiplex signals but also tune operating bands of output channels at the same time.
