- Broadband directional coupler in Rsoft and Lumerical
- Ring Assisted – MZI interleaver design and optimization

Using device level numerical simulation softwares such as Lumerical and Rsoft for the design of photonic devices for specific purpose. The stucture shown above is a broadband, 50:50 directional coupler designed for high speed communication. Other passive or active devices are also possible.

Using Optsim or Optical interconnect, it’s convenient for simulation of large scale systems using pdks exported from device level softwares. Here I demonstrate a 2-stage interleaver using Ring Assisted- Mach Zenhder Interferometer architecture. The flatband performance is preserved in a range of 100nm.
