This photonic model is specifically tailored to model tunable ring switch devices formed by two coupled ring modulators with shared (connected) electrical phase shifters and independent thermal tuners, as shown in the diagram below.
Lumfoundry Templates: Tunable Ring Switch
Quality Assurance Test: tunable_ring_switch_QA
Statistical Modeling Support: No

Model Information
- This model assumes thermal bandwidth to be constant over all bias range.
- This model assumes the directional couplers between the rings and top/bottom buses to have the same coupling characteristics.
- The electrical and thermal phase shifters of both rings are assumed to be identical in properties.
- This model only supports single mode operation.
- This model does not support ring radius as a parameter.
