Optical Enhancements

Earlier this year we looked at Synopsys’s optical modeling tools, including their CODE V toolset.  They recently announced an update with a number of enhancements for a variety of scenarios. It’s illustrative of the range of applications that such a tool finds itself addressing.

  • First, they’ve enabled complex fields to be input to the tool. This means that light sources such as photonic elements and multi-mode lasers can be analyzed using the output of waveguide modeling tools.
  • While their “beam synthesis propagation” (BSP) tool (an element within CODE V) has been able to handle polarization before, it couldn’t deal with so-called “birefringent uniaxial crystals,” which have different indices of refraction for different polarizations, and therefore split a beam into two, depending on the angle of incidence. Of familiar materials, apparently SiC is highly birefringent.
  • They’ve also released pre-analysis improvements to allow the BSP tool to work with a broader range of scenarios, including free-space telecommunications devices with input from optical fiber.
  • Like so many other EDA tools, they’ve joined the multicore world to cut down analysis time.
  • And they have a Glass Expert tool that recommends glass for lenses based on the goals of the system; it’s now been integrated into CODE V.

High Voltage Charging Solution for Energy Storage & Backup Systems

Sponsored by Mouser Electronics and Analog Devices

Today there is growing demand for energy storage with more power, longer range, and longer run time. But the question remains: how can we increase our energy storage given the energy storage mediums on the market today? In this episode of Chalk Talk, Amelia Dalton chats with Anthony Huyhn from Analog Devices about the benefits of high voltage energy storage, why stacked battery cells are crucial to these kinds of systems, how high voltage energy storage systems can reduce conduction loss exponentially and what kind of high voltage charging solutions from Analog Devices are on the market today.
