With RSoft™ Photonic System Design Suite v2015.12, design and fabrication of silicon photonics, photonic integrated circuits, and optical transceivers is accelerated. Suite includes OptSim™ DSP library, which supports transceiver design and bit-error-rate estimation. ModeSYS™ tool includes model that combines multiple CW signals at same wavelength into single spatial field profile. Software also provides interface with Luceda Photonic's IPKISS design framework and updated IMEC component library.
