Maximizing the quality factor to mode volume ratio for ultra-small photonic crystal cavities
Fengwen Wang, Rasmus Ellebæk Christiansen, Yi Yu +2
Small manufacturing-tolerant photonic crystal cavities are systematically designed using topology optimization to enhance the ratio between quality factor and mode volume, Q/V. For…

Fundamental limitations to gain enhancement in periodic media and waveguides
Jure Grgić, Johan Raunkjær Ott, Fengwen Wang +4
A common strategy to compensate for losses in optical nanostructures is to add gain material in the system. By exploiting slow-light effects it is expected that the gain may be enh…
