BeamPROP Product Overview

BPM Software for Waveguide and Circuit Design

BeamPROP™ is the industry-leading design tool based on the Beam Propagation Method (BPM) for the design and simulation of integrated and fiber-optic waveguide devices and circuits. The software has been commercially available since 1994, and is in use by leading researchers and development engineers in both university and industrial environments worldwide.

Benefits

Industry-proven BPM algorithm for fast and accurate device design.
Built-in advanced AWG utility for simplifying router and demultiplexer design.
Advanced capabilities allow for the simulation of complicated devices.
Fully integrated into the RSoft CAD Environment.

Applications

BeamPROP has applications in a wide range of integrated and fiber-optic devices including, but not limited to:

WDM devices such as arrayed waveguide grating (AWG) routers
Switches, e.g. directional coupler-based or digital-y type
Modulators, e.g. Mach-Zehnder type
Multimode interference devices
Passive 1 x N or N x N splitters
Laser structure transverse mode analysis
Standard and specialty fiber design
Gratings
Sensor structures

Features

Superior robust and efficient results via an implementation of the Beam Propagation Method (BPM) based on an implicit finite-difference scheme.
2D and 3D simulation capabilities.
Non-uniform mesh.
Anisotropic and non-linear materials.
Electrode and heater effects.
Polarization effects and coupling via a full-vectorial BPM implementation.
Wide-angle propagation can be improved by multistep Padé approximation techniques, a variable reference wave number, and conformal index mapping of bends to allow for accurate and efficient off-axis propagation.
Bidirectional BPM formulation for considering reflection along the propagation direction to be considered.
Two BPM-based mode-solvers for the computation of modal propagation constants and profiles for both guided and radiation modes for 2D and 3D geometries.
Comprehensive measurement tools to compute fields, power distribution, loss, etc.
Automated parametric studies and design optimization using MOST.
