“…First, all of the structures of [26]- [28] have large size or length; they will not meet the demand of high nanoscale integration. Such as Noual et al [26]-designed structures required more than 1.5 μm separation-distances between Y-junction and the cavities to avoid the coupling between them, Qi et al [28]proposed structures have lager sizes over several micrometers with the period number of N > 5 for the Bragg grating structure, and He et al [27]-proposed structures are even much larger with the period number of N > 10 for the grating-like structure. Second, large size or length also results in relatively high propagation loss; such as Noual et al [26]-designed structure has lower than −5 dB transmittance at the wavelength of 1550 nm.…”

Single output channel selective plasmonic filter structure based on a nanocavity is proposed and numerically simulated by using the finite difference time domain method with perfectly matched layer absorbing boundary condition. The required filtered wavelength can be obtained by selecting an appropriate length of the nanocavity. Nanocavity model and gain model are introduced and analyzed. Two output channels structure based on two nanocavities is proposed to design a subwavelength plasmonic splitter and demultiplexer operating around 1310 nm and 1550 nm. The finite-difference time-domain (FDTD) simulation results reveal that this new structure is suitable for wideband wavelengths demultiplexing. Finally, we propose a multiwavelength demultiplexing structure based on multinanocavity connected to the bus waveguide.

An amplifier that operates on surface plasmon polaritons has been analyzed and simulated. Nonlinearity behavior and the spontaneous emission effects of the plasmonic amplifier are investigated in this paper. A rate equations approach has been used in which parameters are derived from simulation results of the plasmonic amplifier (Silvaco/ATLAS). Details on the method of this derivation are included, which were not previously reported. Rate equations are solved numerically by MATLAB codes. These codes verify the Silvaco results. The plasmonic amplifier operates on surface plasmons with a free-space wavelength of 1550 nm. Results show that, even without the effect of spontaneous emission, gain of the plasmonic amplifier saturates in high input levels. Saturation power, which can be used for comparing nonlinearity of different amplifiers, is 2.1 dBm for this amplifier. Amplified spontaneous emission reduces the gain of the amplifiers, which is long. There is an optimum value for the length of the amplifier. For the amplifier of this work, the optimum length for the small signal condition is 265 μm.
