Do bilayer metasurfaces behave as a stack of decoupled single-layer metasurfaces?
Alfonso Palmieri, Ahmed H. Dorrah, Jun Yang +3
Flat optics or metasurfaces have opened new frontiers in wavefront shaping and its applications. Polarization optics is one prominent area which has greatly benefited from the shap…
Metasurfaces for free-space coupling to multicore fibers
Jaewon Oh, Jun Yang, Louis Marra +4
Space-division multiplexing (SDM) with multicore fibers (MCFs) is envisioned to overcome the capacity crunch in optical fiber communications. Within these systems, the coupling opt…
Compact Dual-Polarization Silicon Integrated Couplers for Multicore Fibers
Julian L. Pita Ruiz, Lucas G. Rocha, Jun Yang +5
Compact fiber-to-chip couplers play an important role in optical interconnections, especially in data centers. However, the development of couplers has been mostly limited to stand…
Intermodal Brillouin scattering in solid-core photonic crystal fibers
Paulo F. Jarschel, Erick Lamilla, Yovanny A. V. Espinel +5
We investigate intermodal forward Brillouin scattering in a solid-core PCF, demonstrating efficient power conversion between the HE11 and HE21 modes, with a maximum gain coefficien…
Nonlinear carrier dynamics in silicon nano-waveguides
Ivan Aldaya, Andres Gil-Molina, Julian L. Pita +3
Carrier recombination dynamics in strip silicon nano-waveguides is analyzed through time-resolved pump-and-probe experiments, revealing a complex recombination dynamics at densitie…
