“…Because the investigated waveguides possess a smooth field profile, several equivalent definitions of mode area can be used. 36 We define the mode area by normalizing the integrated time-averaged electromagnetic energy density (W av ), by its peak value W peak :…”

We demonstrate the realization of confined surface plasmon polariton amplifiers using a thin layer of the organic gain medium 4-dicyanomethylene-2-methyl-6-(pdimethylaminostyryl)-4H-pyran dispersed in a tris(8-hydroxy-quinolinato)aluminum matrix. Complete loss compensation, which occurs at a pump fluence of approximately 200 µJ/cm 2 , is directly observed in the time domain and studied for a range of waveguide lengths. The power dependence is also reported and a significant net gain of 93 dB/mm is observed at the highest fluence.

“…The coupling between the plasmonic and waveguide modes across the gap enables energy storage in non-metallic regions. This hybridization allows SPPs to travel over larger distances with strong mode confinement [23] and the integration of a high quality semiconductor gain material with the confinement mechanism itself.…”

In this article, a 2D plasmonic waveguide loaded with all dielectric anisotropic metamaterial, consisting of alternative layers of Si-SiO 2 , has been theoretically proposed and numerically analyzed. Main characteristics of waveguide i.e. propagation constant, propagation length and normalized mode area have been calculated for different values of ridge width and height at telecommunication wavelength. The respective 1D structure of the waveguide has been analytically solved for the anisotropic ridge as a single uniaxial medium with dielectric tensor defined by Effective Medium Theory (EMT). The 2D structure has been analyzed numerically through FEM simulation using Mode analysis module in Comsol Multiphysics. Both the EMT and real multilayer structure have been considered in numerical simulations. Such structure with all dielectric metamaterial provides an extra degree of freedom namely fill factor, fraction of Si layer in a Si-SiO 2 unit cell, to tune the propagation characteristics compared to the conventional DLSSP waveguide. A wide range of variations in all the characteristics have been observed for different fill factor values. Besides, the effect of the first interface layer has also been considered. Though all dielectric metamaterial has already been utilized in photonic waveguide as cladding, the implementation in plasmonic waveguide hasn't been investigated yet to our best knowledge. The proposed device might be a potential in deep subwavelength optics, PIC and optoelectronics.
