Dispersion properties of coupled waveguides with loss and gain: A full-vectorial analysis
Waveguide structures with a balance of loss and gain have been frequently discussed in the photonic community not only as photonic analogues of quantum-mechanical systems with parity-time (PT) symmetry (breaking), but also as components with potentia...

Nonlinear switching in plasmonic directional couplers
We present a numerical study of all-optical switching in Kerr-nonlinear plasmonic directional couplers. We consider planar couplers that consist of two identical plasmonic slot waveguides and demonstrate the influence of geometrical and optical param...

Simulations of high-Q optical nanocavities with a gradual 1D bandgap
High-quality cavities in hybrid material systems have various interesting applications. We perform a comprehensive modeling comparison on such a design, where confinement in the III?V material is provided by gradual photonic crystal tuning, a recentl...

Analysis of hybrid dielectric-plasmonic slot waveguide structures with 3D Fourier Modal Methods
In this contribution, we theoretically analyze one specific type of a plasmonic waveguide ? the hybrid dielectric-plasmonic slot waveguide, which exhibits very strong field confinement combined with acceptable losses allowing their application in som...

Analysis of tunable one-way terahertz surface-magnetoplasmonic InSb waveguides
We have analyzed nonreciprocal magnetoplasmonic waveguides formed with InSb material, applicable as one-way structures in the THz range. The analysis is based on combination of (quasi)analytical dispersion relation predictions and our magnetooptic Fo...

Analysis of couplers between photonic nanowires and subwavelength grating waveguides
Subwavelength grating (SWG) waveguides offer the freedom of (effective) refractive index variation in the design of integrated optical components and devices in silicon-on-insulator waveguides without significantly increasing fabrication complexity. ...
