Low-cost access to advanced photonic integration technology is becoming available through multi-project wafer runs, using standardized building blocks. We present the design methods and the current status for InP-based photonic ICs.
Optoelectronics with femtojoule or lower energies and compact custom and self-designing optics may enable the lower energy per operation and higher bandwidth density required for continued scaling of information processing. Novel approaches will be presented.
We report the observation of bound states formed by an induced vector soliton and a scalar soliton, the first reported case involving a vector soliton, generated from a weakly birefringent, carbon-nanotube mode-locked fiber laser.
The existence and stability of moving solitons in linearly coupled Bragg gratings with dispersive reflectivity are investigated. The effect of dispersive reflectivity on the stability of solitons is analyzed.
Stability and collisions of moving solitons in a cubic-quintic nonlinear Bragg grating with dispersive reflectivity are investigated. Two disjoint soliton families are found and the outcomes of soliton-soliton collisions are discussed.
We report on the experimental demonstration of mode splitting in a rolled-up semiconductor microtube at telecom wavelengths. Surface scattering causes the splitting of degenerate clockwise and counter-clockwise whispering-gallery modes in the microtube.
Polarization pulse shaper is used in spectral phase retrieval for the first time (to our best knowledge). The implemented dual-quadrature spectral shearing interferometry is self-referenced and can measure pulse trains of 100% duty cycle.
We systematically compare nonlinear media for parametric signal processing by determining the minimum pump power that is required for a given conversion efficiency in a degenerate four-wave mixing process, including the effect of nonlinear loss.
