In this paper, a plasmonic power splitter and a Wavelength Division Multiplexer (WDM) based on metal-insulator-metal (MIM) surface are investigated. By using Finite Difference Time Domain (FDTD) method, the transmission spectra of the suggested devices are extracted. The simulation results demonstrate that the equal transmitted wavelengths of the two output ports can be easily tuned by changing the geometric parameters of the structure. Then, the structure geometries are modified into a WDM. Subsequently, the dependence of demultiplexing wavelengths on geometrical parameters of the structure is investigated. Besides being highly compact and efficient, having narrow-band spectra and low reflectance coefficient are the other main advantages of these devices. Therefore, the power splitter and wavelength division multiplexer presented can be of great interest in a wide range of applications from highly integrated photonic circuits to optical communication systems.

“…Recently, different designs of plasmonic filters based on MIM waveguides configurations have been proposed such as, nanodisk and ring cavities [23], rectangular cavity [24,25], spiral [26], tooth cavity filter [27] and complementary splitring resonators [28]. These devices can be bandpass filters or bandstop filters [29][30][31][32][33][34]. As is well known, the bandwidth is an essential property of SPPs stop-band filters.…”

In this study, we propose an ultra-wideband bandstop filter (UWB-BSF) using a plasmonic MIM waveguide coupled with a stub cavity that is investigated using finite-difference time-domain (FDTD). Air and silver are used as insulators and metals, respectively; silver is characterized by the Drude model. The structure can filter the optical telecommunication wavelengths of 1550 nm and 1310 nm. The transmission peak and the resonance wavelength of the basic structure can be tuned by varying the stub resonator’s length and width. In order to improve the filtering function of the bandstop filter at broad bandwidth in the NIR region with maximum transmission peak, the number of stub resonators is increased to two, three, and four stubs with properly studied lengths and a proper horizontal distance between each two stubs. The bandwidth is enhanced from 350 nm, with two stubs, to 620nm, with three stubs, and 770 nm, with four stubs, respectively. The corresponding filtered wavelength ranges are [1600nm-1950nm], [1330nm-1950nm] and [1180nm-1950nm] respectively. Moreover, with the increase in the number of stubs, the center wavelength achieves a blue shift to lower wavelengths. Further, the paper provides significant applications for plasmonic bandstop filters in highly integrated optical circuits.

“…Optical switching can be achieved through various methods, including electro-optic [18,19], all-optical mechanisms [20,21] and thermal optical mechanisms [3,22,23]. Especially for optical switches and waveguides based on SPPs, they commonly have many excellent merits such as comparative simple structure, low transmission loss, long transmission distance and other useful characteristics [7,24,25]. For example, waveguides with insulator-metal-insulator (IMI) or metal-insulator-metal (MIM) structures have attracted much attention recently because of the above reasons [26][27][28][29].…”

A refractive-index-sensitive plasmonic waveguide, whose transmission characteristics could be controlled remotely by a rake-like switch design, is theoretically studied in the reported work. The distance from the remote control unit to the bus waveguide is more than 0.25 μm, and it still possesses great efficiency even when the distance is increased to 0.535 μm. The switch basically contains two main sections. The first is on the bottom and next to the bus waveguide which functions as a plasmonic resonator that can induce localized surface plasmon resonance (LSPR) and restrict wave propagation at corresponding resonant frequency. The second is on the top and far away from the bus waveguide which functions as a remote controller that can modulate LSPR frequency in the first section. The refractive-index-dependent transmission spectra of this filter were simulated using finite-difference time-domain method. The results have shown that even at a distance as far as 0.5 μm, the ON/OFF switching of the wave propagation in a bus waveguide can still be modulated by adjusting the refractive index of a remote rectangular controller. With only 0.08 difference in refractive index, it could be obtained an on-off switching ratio of 18.7, 20.4 and 25.7 respectively for different waveguides at visible and near infrared wavelength, which shows great potential applications in refractive index sensors and remote-controllable band-stop filters.
