The inability to efficiently tune the optical properties of waveguiding structures has been one of the major hurdles for the future scalability of integrated photonic systems. In silicon photonics, although dynamic tuning has been achieved with various mechanisms, even the most effective thermo-optic effect offers a refractive index change of only $1.86 \times 10^{-4} K^{-1}$. To enhance this small change, light recycling based on resonators has been employed in order to realize efficient…
