Extending the spectral operation of multimode and polarization-independent power splitters through subwavelength nanotechnology
Raquel Fernández de Cabo, David González-Andrade, Pavel Cheben +1
Power splitters play a crucial role in virtually all photonic circuits, enabling precise control of on-chip signal distribution. However, state-of-the-art solutions typically prese…
Low-loss directional coupler for the C, L and U bands based on subwavelength gratings
Jaime Vilas, Raquel Fernández De Cabo, Irene Olivares +3
Directional couplers are ubiquitous components for power distribution in silicon photonics integrated circuits. Despite significant advances in their performance, architectures pro…
Broadband three-mode converter and multiplexer based on cascaded symmetric Y-junctions and subwavelength engineered MMI and phase shifters
David González-Andrade, Irene Olivares, Raquel Fernández de Cabo +3
Mode-division multiplexing has emerged as a promising route for increasing transmission capacity while maintaining the same level of on-chip integration. Despite the large number o…
Experimental characterization of an ultra-broadband dual-mode symmetric Y-junction based on metamaterial waveguides
Raquel Fernández de Cabo, Jaime Vilas, Pavel Cheben +2
Silicon photonic integrated circuits routinely require 3-dB optical power dividers with minimal losses, small footprints, ultra-wide bandwidths, and relaxed manufacturing tolerance…
