Theory of Linewidth-Narrowing in Fano Lasers
Yi Yu, Aref Rasoulzadeh Zali, Jesper Mørk
We present a general theory for the coherence of Fano lasers based on a bound state in the continuum. We find that such lasers enable orders of magnitude reduction of the quantum-l…

Suppression of coherence collapse in semiconductor Fano lasers
Thorsten S. Rasmussen, Yi Yu, Jesper Mork
We show that semiconductor Fano lasers strongly suppress dynamic instabilities induced by external optical feedback. A comparison with conventional Fabry-Perot lasers shows orders…

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…
