Many-mode grating couplers by avoiding undesired couplings
Nazar Pyvovar, Hao Li, Zhaowei Dai +1
To couple many independent modes from free space to on chip, the key challenge is not enhancing the many necessary coupling rates (scattering-matrix elements) between targeted mode…
Multimode grating couplers via foundry-compliant inverse design
Hao Li, Nazar Pyvovar, Zhaowei Dai +1
We apply a systematic inverse design approach to discover foundry-compliant, multilayer grating couplers that can efficiently couple a number of independent waves from free space t…
Coherent Control of Wave Scattering via Minimal-Parameter Tuning of Complex Spectra
Ali H. Alhulaymi, Nazar Pyvovar, Philipp del Hougne +2
We introduce and validate a theoretical framework for coherent control of multichannel linear scattering to route waves through complex geometries with multiple scattering. We show…
Gyrotropic metamaterials with tailored magnetization
Nazar Pyvovar, Sadi Ayhan, Carl Pfeiffer +3
Magnetic materials are crucial in nonreciprocal electromagnetic devices, such as isolators, circulators, and nonreciprocal phase shifters. However, their use is often limited by th…
Optical transmission of a moving Fabry-Perot interferometer
Nazar Pyvovar, Lingze Duan
Fabry-Perot interferometers have been widely studied and used for well over a century. However, they have always been treated as stationary devices in the past. In this paper, we i…
Few-cycle excitation of atomic coherence: A closed-form analytical solution beyond the rotating-wave approximation
Nazar Pyvovar, Bing Zeng, Lingze Duan
Developing an analytical theory for atomic coherence driven by ultrashort laster pulses has proved to be challenging due to the breakdown of the rotating wave approximation (RWA).…
