Controllable finite ultra-narrow quality-factor peak in a perturbed Dirac-cone band structure of a photonic crystal slab
Alex Y. Song, Akhil Raj Kumar Kalapala, Ricky Gibson +9
We show that by using a perturbed photonic Dirac-cone, one can realize ultra-narrow and finite Q-factor peak in the wavevector space, with both the peak value and the width separat…

Laterally confined photonic crystal surface emitting laser based on monolayer tungsten disulfide operating at room temperature
Xiaochen Ge, Momchil Minkov, Shanhui Fan +2
We report a photonic crystal surface emitting laser using monolayer tungsten disulfide as the gain medium. The cavity design utilizes a heterostructure in the photonic crystal latt…

First-Principles Threshold Calculation of Photonic Crystal Surface-Emitting Lasers Using Rigorous Coupled Wave Analysis
Alex Y. Song, Akhil Raj Kumar Kalapala, Weidong Zhou +1
We show that the threshold of a photonic crystal surface-emitting laser can be calculated from first-principles by the method of rigorous coupled wave analysis (RCWA), which has be…
