Abstract: Systems and methods for designing photonic integrated circuits (PICs) include a simulation program with virtual optical probing functions and, optionally, bidirectional optical signal propagation simulation. For probing, a processor receives an output expression specifying a virtual optical probing function (e.g., for power in dBm, etc.) and a net within a PIC design. If different simulation types are enabled, the expression specifies simulation type. If bidirectionality is enabled, the expression specifies the forward or reverse direction. In response, the processor accesses the PIC design and results of simulation(s) thereof and calculates and outputs an optical signal parameter value for the specified net. For bidirectionality, component descriptions of photonic device cells define, at each input/output terminal, pins associated with each of multiple optical signal components in both directions and, when such cells are incorporated into a PIC design, analytical functions employ the pins to model the optical signal components in both directions.
