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…

Tabletop single-shot extreme ultraviolet Fourier transform holography of an extended object
Erik B. Malm, Nils C. Monserud, Christopher G. Brown +6
We demonstrate single and multi-shot Fourier transform holography with the use of a tabletop extreme ultraviolet laser. The reference wave was produced by a Fresnel zone plate with…
