An efficient sensitivity analysis approach for quantum nanostructures is proposed. The imaginary time propagation method (ITP) is utilized to solve the Time Dependent Schrödinger’s Equation (TDSE). Using this method, an extraction of all the modes and their sensitivity with respect to all the design parameters have been performed with minimal computational effort. The sensitivity analysis is performed using the Adjoint Variable Method (AVM) and results are comparable to those obtained using Central Finite Difference Method (CFD) applied directly on the response level.
Using plasmonic waveguide for interconnects application is very promising direction to achieve high density integration
a good size compatibility with electronic devices. Thus, proposing compact and efficient functional plasmonic devices is
or prime essential to achieve the required system functionalities. Power splitters are widely used as one of the important
component of the optical interconnects and integrated photonic and plasmonics devices. We propose a simple, ultra
compact and wideband balanced power divider. The advantage of this device is compactness and ability to split the
power over wideband with negligible imbalance. The device is based on plasmonic slot waveguide configuration and has
submicron total foot print. To achieve the proposed optimized design, a simple and novel analytical model is utilized for
modelling the behavior or any plasmonic structure using circuit model.
