This section includes examples for a range of applications and devices, including graphene devices, electronic components, magneto optical kerr effect, Faraday effect, and more.
Graphene
Graphene is a monolayer of carbon atoms arranged in a two-dimensional honeycomb lattice. The optical properties of graphene depend on the electronic Fermi level (or chemical potential), which can be adjusted by doping or biasing. In addition to this tunability, graphene offers other interesting optical properties like propagation of surface plasmons and strong nonlinearities. Due to these interesting properties, graphene is being extensively studied and considered for a wide range of optical devices, including nanoscale electro-optic modulators (right) and broadband polarizers.
Electronic components
Electronic circuits consist of active components such as diodes, transistors, Integrated Circuits, and passive components such as capacitors, resistors, etc. Today, most electronic devices use semiconductor components to perform electron control. Lumerical's powerful drift-diffusion solver CHARGE is capable of modeling steady-state and transient behavior of charge carriers in these semiconductor components.
Magneto optical Kerr effect
The Magneto-Optic Kerr Effect (MOKE) describes the changes to light reflected from a magnetized surface.
Faraday effect
A Faraday rotator rotates the polarization of the incident light via the magneto-optical Faraday effect. We will also show how this effect can be utilized to create an optical isolator, allowing for transmission of light in only one direction (and preventing unwanted feedback).
Time reversal
