::::::English Description:::::: The optimal design of a given optical communication system depends directly on the choice of fiber parameters. OptiFiber uses numerical mode solvers and other models specialized to fibers for calculating dispersion, losses, birefringence, and PMD. Meshless Mode Solvers for LP and Vector Modes: Optical fibers may consist of an arbitrary number of concentric layers of lossless materials, and graded index fibers can be approximated using a sequence of constant index layers. OptiFiber 2.0 mode solvers find an exact solution based on matching boundary conditions at layer boundaries instead of relying on meshes to approximate the structure. These advanced mode solvers should be especially useful for multimode fiber calculations, where there are many modes in the spectrum. Another advantage...
::::::English Description:::::: OptiGrating uses the Coupled Mode Theory to model the light and enable analysis and synthesis of gratings. A complex grating is approximated by a sequence of uniform segments, and analyzed by connecting the segments with the well-known Transfer Matrix Method. This gives the designer the information needed to test and optimize grating designs. Applications WDM add/drop, narrow and broadband fiber and waveguide filters Fiber Bragg reflectors EDFA gain flattening elements Dispersion compensators for fiber communications Sideband suppression using grating apodization Fiber and waveguide sensors Long Period Gratings with coupling to cladding modes Main Features • Arbitrary fiber/waveguide profile.• Arbitrary grating profile including arbitrary apodization and chirp.• Various calculation options in the spatial, spectral and time domains. • Sensors:...

::::::English Description:::::: OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and the nonlinear phenomenon. The core program of OptiFDTD is based on the finite-difference time-domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary condition – Uniaxial perfectly matched layer (UPML) boundary condition. The algorithm solves both electric and magnetic fields in temporal and spatial domain using the full-vector differential form of Maxwell s coupled curl equations. This allows for arbitrary model geometries and places no restriction on the material properties of the devices. OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization...
TGS Open Inventor 7.1 NET for VS2k8是目前世界上最被广泛使用的对象导向绘图软件开发接口(API)，对于程序开发者而言Open Inventor具有跨平台的能力，因此只要撰写一份程序代码即可编译成在Unix/Linux和Microsoft Windows可执行的程序，至于程序开发使用的语言目前支持C++和Java。 Open Inventor将开发绘图程序所需要呼叫的复杂函式，转为易于使用的对象，使得绘图程序的建立变得更有效率。另外关于绘图场景的管理可以用数据库的概念来进行，比如开发者可以建立、修改或是将对象组合成3-D的阶层结构(如树状结构)。透过使用这些庞大内建的对象，开发者可将主要时间花在指挥这些对象如何运作与建立其关联性，或是研究领域的仿真运算等。Product:TGS Open Inventor 7.1 NET for VS2k8 Lanaguage:English Platform:/WinNT/2000/XP Size:182MB
