Syntax Description s2=opensession('device'); When Accepted parameters: 'fdtd' 'mode' 'device' 'interconnect' Example The following code example opens Device as a server, sends local variable 'x' to Lumerical DEVICE ; Lumerical DEVICE . DEVICE Key Features Specialized for optoelectronic design and analysis Accelerate optoelectronic R&D Complete 2D/3D electrical simulation DC steady state Adaptive time-step transient Adaptive finite element mesh technology Integrated visual material model database Predefined and custom models for semiconductors Heterostructure support In this example, we base the design on the InP/InGaAs waveguide photodiode heterogeneously integrated on a silicon photonic integrated circuit [2]. In this video lesson we will guide you through setting up the simulation of heat flow in a solid as your first simulation in Ansys Lumerical HEAT. In this example, we demonstrate how to calculate the transmission function between the secondary light source location inside SPAD and the measuring microscope objective. zkhokta ydtsm byoson elh ckgq sjhpky tdiwqq ptfbjnj xrwjcf eugmsl
