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…
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…
Simultaneous Mode and Wavelength Division Multiplexing On-Chip
Lian-Wee Luo, Noam Ophir, Christine Chen +4
Significant effort in optical-fiber research has been put in recent years into realizing mode-division multiplexing (MDM) in conjunction with wavelength-division multiplexing (WDM)…
Transformation Inverse Design
David Liu, Lucas H. Gabrielli, Michal Lipson +1
We present a new technique for the design of transformation-optics devices based on large-scale optimization to achieve the optimal effective isotropic dielectric materials within…
Perfect imaging in the optical domain using dielectric materials
Lucas H. Gabrielli, Ulf Leonhardt, Michal Lipson
The promise of perfect imaging in the optical domain, where light can be imaged without aberrations and with ultra-high resolution, could revolutionize technology and nanofabricati…
Silicon nanostructure cloak operating at optical frequencies
Lucas H. Gabrielli, Jaime Cardenas, Carl B. Poitras +1
The ability to render objects invisible using a cloak - not detectable by an external observer - for concealing objects has been a tantalizing goal1-6. Here, we demonstrate a cloak…
Multi-wavelength source at ITU-T grid based on ultra-flattened dispersion photonic crystal fibers
Arismar Cerqueira S., J. D. Marconi, L. H. Gabrielli +4
We report on the development of a multi-wavelength source locked to the ITU-T grid at 100 GHz spacing and based on ultra-flattened dispersion photonic crystal fibers. The ITU-T gri…
