The Beam Propagation Method (BPM) is widely used in numerical simulations of optical waveguides that vary in the propagation direction.
For low to medium index contrast, the BPM method allows fast and accurate 2D and 3D simulations.
In 1992, Optiwave pioneered the first commercially available simulation design tool tailored for the design of complex optical waveguides, OptiBPM. Since its inception, OptiBPM has matured into a comprehensive design suite in use by leading research institutions and universities worldwide.
Based on the Beam Propagation Method (BPM) of simulating light passage through any waveguide medium, OptiBPM allows designers to observe computer-simulated light field distribution and examine the radiation and the guided field, simultaneously. The introduction of optimized fiber vector and LP mode solvers allow for more simulation flexibility and improved accuracy.
“OptiBPM is easy to use, flexible, powerful and fast,” says Carl Tuttle from Lockheed Martin. “Additionally, the support we have received from Optiwave has been uniformly excellent.” The latest edition of OptiBPM includes new optimization algorithms which can help increase the accuracy of complex simulations. Optimization engines include the Golden Search for one dimension, Simplex and Direction Set methods for multidimensional searches.
The Power of OptiBPM:
• Ready to accept any refractive index distribution as input. Once this input is done, modes can be found, and BPM based propagation simulations can be performed.
• Can simulate higher order Padé approximants in 3D, such as Padé (4,4) in 3D full vector anisotropic BPM. An exclusive feature in OptiBPM.
• Flexible user environment, with the capability to create long and wide planar lightwave circuits.
• Full parameterization of waveguide shapes, including: Elliptical, Parabolic, Taper, Ring and S-Bend Cosine Taper.
