  • Dynamic WDM Channel Equalizer

    This demo illustrates a possible realization of a dynamic channel equalizer. For this purpose, two arrayed waveguide gratings (AWGs) are integrated with an array of active phase shifters to create a series of Mach–Zehnder interferometers (MZIs) which allow to equalize each wavelength (WDM channel) independently.

  • Integrated Recirculating Optical Buffer

    This demo illustrates how time-and-frequency-domain modeling (TFDM) technique allows to easily perform such otherwise complex simulations as modeling Integrated Recirculating Optical Buffers, which mix active components and small-size and dispersive passive PIC Elements, with strong feedback loops between them.

  • Wavelength Conversion Based on
    SOA Integrated with Multi-Ring Resonator

    This demo illustrates usage of a hybrid time-and-frequency-domain simulation technique for accurate and numerically efficient simultaneous modeling of SOAs and multi-ring resonators with small ring radii. Here, the SOAs are modeled employing traditional time-domain approach, while multi-ring resonators are modeled employing SMATRIX simulation domain with fully-automatic design of FIR filters for time-domain description of the multi-ring resonator structure as a whole.
