Complete 2π Phase Control by Photonic Crystal Slabs
Mingsen Pan, Zhonghe Liu, Akhil Raj Kumar Kalapala +3
Photonic crystal slabs are the state of the art in studies for the light confinement, optical wave modulating and guiding, as well as nonlinear optical response. Previous studies h…
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…
Scalable microcavity-coupled emitters in hexagonal boron nitride
Nicholas V. Proscia, Harishankar Jayakumar, Xiaochen Ge +5
Scalable integration of bright emitters in quantum photonic structures is an important step in the broader quest to generate and manipulate single photons via compact solid-state d…
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…
229 nm UV LEDs using p-type silicon for increased hole injection
Dong Liu, Sang June Cho, Jeongpil Park +10
Ultraviolet (UV) light emission at 229 nm wavelength from diode structures based on AlN/Al0.77Ga0.23N quantum wells and using p-type Si to significantly increase hole injection was…
