A new compact model for HfO2-based ferroelectric tunnel junction (FTJ) memristors is constructed based on detailed physical modeling using calibrated TCAD simulations. A multi-domain configuration of the ferroelectric material is demonstrated to prod

2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD).
Presented here are two important devices that cannot be modeled accurately and/or tractably by a single simulation technique. Simulation flows to address each device are presented. The first is a patterned Light Emitting Diode (LED), the optical mode

We present a comprehensive numerical model to simulate self-heating effects of oxide-confined vertical-cavity surface-emitting lasers (VCSELs) under continuous-wave operation. The model self-consistently accounts for the close interaction between opt

A lattice temperature model is derived for oxide-confined vertical cavity surface emitting lasers (VCSELs) based on carrier transport and the conservation of energy. Peltier heat is caused by the bandedge and quasi-Fermi level discontinuities at a he

We report novel design considerations for graded separate confinement heterostructure (SCH) cavities of oxide-confined vertical-cavity surface-emitting lasers (VCSELs). Using a self-consistent effective-index method, we have analyzed ungraded, linear

We present detailed numerical simulations to clarify the important role that the nonuniformity of the transverse optical mode plays for the high-speed response of oxide-confined vertical-cavity surface-emitting lasers (VCSELs). The comprehensive lase

The comprehensive semiconductor laser simulator, Minilase, has been extended to simulate the dynamic response of vertical cavity surface emitting lasers (VCSLs). Unlike conventional rate equation approaches, Minilase is capable of correctly modelling

Our numerical simulations of vertical cavity surface emitting lasers with Minilase demonstrate that a diffusion capacitance is induced by the minority carriers accumulated in the separate confinement regions. This diffusion capacitance is shown to be

The operations of three-guide couplers are usually controlled by the width and refractive index of the guides. However, when rib waveguides are used in three-guide couplers and power dividers, we propose to use the dimensions of the ribs as the gover
