Version 2011 device simulators released (Aug 3rd, 2011)

Crosslight Software proudly announces the release of Version 2011 of Crosslight device simulation software pacakges (APSYS, CSUPREM, LASTIP and PICS3D) with major upgrades making them the most advanced in the industry. These major upgrades are summarized as follows:

Polarization charges of nitride materials are implemented using an intrinsic macro property and are automatically computed between material interfaces or within graded regions. This provides great convenience in modeling GaN based semiconductors of complicated geometry and composition grading or other compounds with built-in polarization.
Major progress in 3D simulation setup procedure: User may start from the .layer format (using the user-friendly GUI LayerBuilder) to design the 2D cross section of a device. Then mask data (usually of GDS format) may be used to convert the 2D cross section into 3D mesh.
Major upgrade of GaN-based material macros to incorporate the latest understanding of the IQE droop in blue LED. As a result, IQE droop as observed in experiments is routinely reproduced in sumulation.
Introduced an efficient new 3D mesh scheme so that mesh plane of any shapes (such as bended shapes) no longer has to cut through the whole device simulation area. This results in substantial mesh savings when handing devices with details of complicated local geometries such as small holes or rods. The new mesh has been incorporated into the friendly graphic user inerface program MaskEditor.
Substantial speed-up in the computation of quantum states in devices with hundreds of quantum wells (such as in QCL and typeII PD).
New quantum well model with self-consistent solutions have been developed for many difference types of applications and device configurations, such as for MQW system within nanowire and nanotubes, and LED with complex geometries. Refer to our LED presentation page for details.
Substantial improvement of non-local transport, optical gain, interband tunneling and temperature dependence in quantum cascade lasers and typeII MQW PD.
More convenient user interface with CSuprem and related GUI tools such as MaskEditor and SemiCrafter so that complicated 3D structures can easily be created without loss of accuracy as found in devices with plane geometries.
APSYS: LED raytracing capability enhanced to include multiple wavelengths and realistic simulation phosphor LED has been demonstrated.
APSYS: Substantial improvement in FDTD so that power extraction in LED with textured interfaces can be simulated more accurately.
PICS3D: power coupling between difference cavities, useful for ring laser which relies on flexbile control or power flow between cavilites.
PICS3D: the QCL model from LASTIP is now available in PICS3D.
Numerous minor improvements of data I/O and plotting.

What's New in 2010

Version 2010 device simulators released(August 26, 2010)

Crosslight Software proudly announces the release of Version 2010 of Crosslight device simulation software pacakges (APSYS, LASTIP and PICS3D). Improvements and new features are briefly summarized as follows:

Numerical models

Implemented stacked 3D mesh with different plane structures. This allows flexibility in 3D simulation with mesh imported from different mesh generators/process simulations.
Taper 3D structure handled in a more flexible manner.
Flexibility in defining a limited electrical simulation volume while all other volumes can be used for optical simulation.
Added the choice of other matrix linear solvers such as MUMPS and Pardiso. New option of graphic processing unit (GPU) based accelation for large mesh.
FDTD : interface programs are improved so that both MIT MEEP and the GPU-accelerated libraries from Acceleware can be accessed.
Regrid function improved to include CSuprem imported mesh/doping.
Csuprem bulder interface improved so that complicated tapered waveguide LD/SOA can be built using CSuprem and simulated by PICS3D.
More bias dependent output impelemented so that potential, carriers, recombinations and spatial integrals can be plotted versus bias. Fermi-level against density of state diagram may also be exported.

Physical Models

Exclusion of non-emission wavelength from LED IQE calculation which helps explain the droop effect more accurately.
Opitcal birefringence effect taken into account for waveguide modeling. Use of miller index to define growth direction of GaN based wurtzite crystals.
Automatic scan of input wavelength for photosensitive devices which were previously performed by GUI tool function "series".
Amplified spontaneous emission (ASE) spectrum model improved so that both single wavelength and continuous spectrum can be treated (for SOA and SLED).
BPM guided wave solver rewritten using the latest FD-BPM technology.
Non-local transport model involving MQW/supperlattice has been implemented so that type-II PD and QCL current flow / injection can be treated. As a result, QCL with hundreds of QW has been demonstrated in electrical-optical simulation

Major progress in quantum cascade laser modeling(June 10, 2010)

As a major progress in modeling and simulation of quantum cascade laser (QCL), Crosslight has succeeded in simulating a full QCL with tens or hundreds of MQW periods in a 2/3 dimensional simulation software (LASTIP or PICS3D). It is now possible to optimize QCL design using a drift-diffusion based optoelectronic simulator with self-consistent quantum mechanical corrections. For details, click here.

Graphics processing unit (GPU) accelerated 3D simulation achieved(June 4, 2010)

Crosslight is pleased to announce the availability of graphics processing unit (GPU) accelerated versions of device simulators (PICS3D, APSYS and LASTIP). Through an inovative GPU software technology, Crosslight has achieved stable and converging acceleration of all tested 3D device simulations. As an indication, for 3D simulation of 100,000 mesh points (matrix order 300,000) using a single graphic card Tesla C1060, over two times of speed-up (1/2 of simulation time reduction) has been achieved as compared with Intel i7 CPU. More recent GPU and multiple GPU should scale up better. Interested users of Crosslight is encouranged to contact Crosslight for a free demo.
