Breaking the cavity linewidth limit of resonant optical modulators
Wesley D. Sacher, William M. J. Green, Solomon Assefa +5
Microring optical modulators are being explored extensively for energy-efficient photonic communication networks in future high-performance computing systems and microprocessors, b…
Mid-infrared optical parametric amplifier using silicon nanophotonic waveguides
Xiaoping Liu, Richard M. Osgood, Yurii A. Vlasov +1
All-optical signal processing is envisioned as an approach to dramatically decrease power consumption and speed up performance of next-generation optical telecommunications network…
Deterministic tuning of slow-light in photonic-crystal waveguides through the C and L bands by atomic layer deposition
Charlton J. Chen, Chad A. Husko, Inanc Meric +5
We demonstrate digital tuning of the slow-light regime in silicon photonic-crystal waveguides by performing atomic layer deposition of hafnium oxide. The high group-index regime wa…
Transmission of Slow Light through Photonic Crystal Waveguide Bends
Solomon Assefa, Sharee J. McNab, Yurii A. Vlasov
The spectral dependence of a bending loss of cascaded 60-degree bends in photonic crystal (PhC) waveguides is explored in a slab-type silicon-on-insulator system. Ultra-low bending…
Mapping the optical properties of slab-type two-dimensional photonic crystal waveguides
Eric Dulkeith, Sharee J. McNab, Yurii A. Vlasov
We report on systematic experimental mapping of the transmission properties of two-dimensional silicon-on-insulator photonic crystal waveguides for a broad range of hole radii, sla…
Coupling into the slow light mode in slab-type photonic crystal waveguides
Yurii A. Vlasov, Sharee J. McNab
Coupling of external light signals into a photonic crystal waveguide becomes increasingly inefficient as the group velocity of the waveguiding mode slows down. We have systematical…
