We report simulated performance for an integrated and compact silicon photonic quasi-dichroic filter with ≥10 dB/nm roll-off and ≥20 dB extinction ratio between pass and stop bands. Additionally, the cutoff wavelength and compensation for fabrication error are each thermally tunable. The functional dichroic bandwidth is ≈80 nm, which spans most practical use cases.

We report the performance of a compact model for the effective index of SOI wire waveguides, showing exceptional agreement with simulated effective index and confinement factors. The development of such a model represents a potential pathway toward better modeling of silicon photonic devices in commercial foundry processes.
