“…Another important parameter is crosstalk values for demultiplexers. Crosstalk, measured in decibels (dB), represents the effect of adjacent channels on the designated channel when an optical wave is sent to the demultiplexer input (Abderrahmane et al 2023). Table 1 shows the crosstalk values of the 1 × 2 demultiplexer.…”

Confinement of the light at the subwavelength scale makes photonic devices more efficient in applications such as optical filtering, switching, and sensing with their low dimensions. Metal-insulator- metal waveguide-based configurations present many paths for manipulating light at the wide range of the electromagnetic spectrum. For that purpose, in this study, a wavelength demultiplexer (WDM) based on a metal-insulator-metal (MIM) waveguide is numerically investigated by finite difference time domain (FDTD) method. Proposed WDMs have cascade polygon resonators. After optimizing the fundamental filter, this structure is formed as 1×N demultiplexers. The proposed demultiplexers have two- and three channels. The minimum full width at half-maximum (FWHM) value for these channels is 20.02 nm and the maximum quality factor value is 47.7 at 954.9 nm wavelength. The minimum crosstalk value is obtained as -30.37 dB for this study. The proposed 1×N demultiplexers have potential tools to design low-cost integrated optical circuits for specific wavelengths.

“…In [24], the multimode interference effect is utilized to make MIM waveguide-based demultiplexer and splitter with an extinction ratio of ~ 11.6 dB. Moreover, there are several other interesting works on plasmonic demultiplexers [25][26][27][28]; however, all of them failed to provide a mechanism for lighting coupling to the MIM waveguide. This is the reason, there is no experimental demonstration of the plasmonic device based on a MIM waveguide is yet available [29].…”

In this work, a numerical analysis of a compact 1 × 2 plasmonic demultiplexer based on a metal–insulator-metal (MIM) waveguide is presented. Two hollow circular cavities are side coupled to the bus waveguide on both sides. The cavities are designed in such a way that they resonate at the working wavelength of 1310 nm and 1550 nm. The mechanism of light coupling to an MIM waveguide has not been considered in previous studies. Therefore, a silicon tapered mode converter is integrated with a plasmonic demultiplexer for the efficient conversion of a dielectric to a plasmonic mode. The footprint of the device is 6 μm × 6 μm. The crosstalk at P1 and P2 is ~ 14.07 dB and ~ 13.67 dB for the transmission wavelength of 1310 nm and 1550 nm, respectively.
