elec_eq_ckt_data (optional) |
struct with fields described in elec_eq_ckt_data | Data required for modeling the electrical equivalent circuit for accurate electro-optic simulations. For more information on the electrical equivalent circuit, see Electrical equivalent circuit details in the photonic model page. |
| opt_passthrough (optional) | number | Passthrough optical transmission in dB. The same value is used to calculate the unabsorbed input signal from opt_1 exiting through opt_2 and vice versa. Used in models with dual optical port only. If not provided then the model uses a default value of -2000 dB (i.e., no passthrough optical signal at the opposite ports). |
