High-index dielectric resonators support different types of resonant modes. However, it is
challenging to achieve a high-Q factor in a single dielectric nanocavity due to the non …

The integration of Ge on Si for photonics applications has reached a high level of maturity:
Ge photodetectors are available on the Si platform in foundry processes, and Si/Ge …

We propose a cascaded asymmetric resonant compound grating (ARCG) for high-
