RSoft-Photonics-CAD-Suite

RSoft Design Group produces photonic design and simulation software for both passive and active optical components for optical communications, optoelectronics and semiconductor manufacturing. The software is used by these organizations to reduce costs of creating a physical prototype, to assess design risks, and to assist in the discovery of new products from creating “what if” product scenarios. These key benefits enable a faster design process and shorter time to market.

RSoft currently addresses both passive and active devices through two design suites, a Passive Device Suite and an Active Device Suite. Each suite has a CAD environment, simulation engines and can utilize an optimization utility. Some of the key applications of our products include:

The RSoft CAD™ is the core program in the RSoft Photonic Suite, and allows researchers and engineers to create systems for the design of waveguide devices, optical circuits, and other photonic devices. It acts as a control program for RSoft’s passive device simulation modules, including BeamPROP, FullWAVE, BandSOLVE, GratingMOD, and DiffractMOD, and defines the most important input required by these programs: the material properties and structural geometry of the photonic device to be studied.

Layout Capabilities The complete layout capabilities of the RSoft CAD have been designed from the ground up to accommodate the special needs of photonic devices and circuits. Fundamental objects such as straight, tapered, curved, y-branched waveguide segments and lenses can easily be selected from the toolbar, and graphically added to the circuit using the mouse. In addition to standard objects, the CAD also allows for the creation of customized components using mathematical equations or data files. Positioning coordinates may also be specified directly, either absolutely, or through relative offsets or angles with respect to any other waveguide component. At any time, one or several components may be selected and moved, scaled, deleted, or reinserted. Our unique design approach is an extremely flexible system in which the desired logical arrangement can be maintained as subsequent placement.

Object-Oriented Design

Each individual component has its own set of properties that can be accessed with a right click of the mouse. Parameters include shape information, such as taper or bend type and magnitude, and optical properties, such as refractive index profile type and value. This unique object-oriented input model is extremely natural and flexible. Each parameter of a component (e.g. position coordinates, width, index) can be specified by an arithmetic expression involving user-defined variables, rather than simply being a constant number. Thus, a waveguide circuit might have several angled waveguides, each with a different relative angular value. By using formulas to define each waveguide�s angle, the entire circuit can be modified by simply changing the value of a single variable, without having to redraw or otherwise edit
