Vancouver, BC (May 20, 2015)

Lumerical Solutions, Inc., a global provider of photonic design software, announced the 2015b release of its products FDTD Solutions 8.12, MODE Solutions 7.6, DEVICE 4.6 and INTERCONNECT 5.0. New photonic component and integrated circuit design and analysis features in the 2015b release include:

  • Improved graphene modeling in FDTD Solutions and MODE Solutions uses a surface conductivity model combined with a new 2D surface primitive to dramatically reduce simulation time and improve predictive capabilities
  • A one-dimensional traveling wave laser model in INTERCONNECT provides a self-consistent framework to account for the complex interactions of semiconductor lasers tightly integrated with photonic integrated circuits
  • New model library management features in INTERCONNECT allow for the secure generation and sharing of a compact model library which contains advanced frequency- and time-domain photonic circuit models
  • The dataset builder in DEVICE, FDTD Solutions and MODE Solutions allows designers to define complex structures with spatially-varying material properties, including doping profiles, generated by other software tools, modeling frameworks, and TCAD process simulators

“Lumerical’s FDTD Solutions and MODE Solutions are integral to our development methodology for waveguides and couplers in our planar MEMS solutions for optical switching and tunable lasers,” says Francois Menard, CTO and co-founder of Aeponyx, a telecommunications equipment manufacturer specializing in WDM solutions for passive optical networks (PON) and data center interconnects. “With the introduction of the laser model in INTERCONNECT, we are able to create a complete circuit model and optimize the externally tunable laser cavities used in our solutions.”

Along with key new features for photonics designers, the 2015b release builds on the photonic integrated circuit design features developed with PhoeniX Software’s OptoDesigner. Advances in the workflow between INTERCONNECT and OptoDesigner support back annotation and layout versus schematic (LVS) verification of post layout, packaging ready designs. The interface enables a flexible schematic driven or layout driven design methodology and, along with accurate coordination of schematic and physical layouts through all stages of design from concept to final tapeout, allows designers to improve design reliability and yield.
