We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment cophasing errors are a primary contributor to contrast limits on Keck and will be nece

We demonstrate a modular design approach for large metasurface-based optical concentrators. In this approach, each concentrator is split into a collection of sublens modules. Each sublens module has an off-axis focal point, and this point is located

We theoretically investigate graphene plasmons in the presence of a low density of adatoms on the graphene surface. The adatoms can significantly modify the conductivity and plasmonic properties of graphene and may produce a level splitting with the

In this paper, we will report our recent efforts in achieving high performance in Antimonides type-II superlattice (T2SL) based infrared photodetectors using the barrier infrared detector (BIRD) architecture. The high operating temperature (HOT) BIRD

We have designed plasmonic filters that simultaneously perform wavelength and polarization filtering in the wavelength range 3–5 micrometers. In this work we outline the design and present the simulated results of our filters. The filters consist o

In this work, we utilize metasurface lenses (metalenses) as optical concentrators for photodetectors. In particular, we design and fabricate metalenses for the wavelength range 3.5 -4.5 μm and integrate them with infrared photodetectors. Infrared ph

This work analyses how impurities and vacancies on the surface of a graphene sample affect its optical conductivity and plasmon excitations. The disorder is analysed in the self-consistent Green's function formulation and nonlocal effects are fully t
