Mode conversion losses in SOI photonic wire based racetrack resonators

We found that in low loss SOI sub-micron photonic wire racetrack resonators, when the air gap between the resonator and access waveguide is < 120 nm, the mode conversion losses in the coupling region dominate bending and propagation losses.
