We theoretically and experimentally study the nonlinear propagation of polychromatic light in curved waveguide arrays. We show that at moderate light powers the nonlinear self-action breaks the left-right symmetry of the polychromatic beam, resulting in the separation of different spectral components owing to the wavelength-dependent spatial shift. At high light powers a diffraction-managed pol...

We demonstrate all-optical demultiplexing of a high-bandwidth, time-division multiplexed 160 Gbit/s signal to 10 Gbit/s channels, exploiting slow light enhanced four-wave mixing in a dispersion engineered, 96 μm long planar photonic crystal waveguide. We report error-free (bit error rate<10⁻⁹) operation of all 16 demultiplexed channels, with a power penalty of 2.2-2.4 dB, highlighting the poten...

A Two-Dimensional (2D) vortex electrons sorting method that can be used for Orbital Angular Momentum (OAM) transmission is proposed, which separate with different Topological Charges (TCs) into collectors in the 2D space. Compared traditional One-Dimensional (1D) sorting, distance increased from micrometer level to millimeter level, reduces inter-mode crosstalk and improves accuracy. Therefore,...

MOTIVATION Pooling multiple samples increases the efficiency and lowers the cost of DNA sequencing. One approach to multiplexing is to use short DNA indices to uniquely identify each sample. After sequencing, reads must be assigned in silico to the sample of origin, a process referred to as demultiplexing. Demultiplexing software typically identifies the sample of origin using a fixed number of...

We demonstrated all-optical demultiplexing of 160-Gb/s signal to 40and 80-Gb/s by a Mach-Zehnder Interferometric all-optical switch, where the picosecond cross-phase modulation (XPM) induced by intersubband excitation in InGaAs/AlAsSb coupled double quantum wells is utilized. A bi-directional pump configuration, i.e., two control pulses are injected from both sides of a waveguide chip simultane...

Today’s communication WDM or OTDM networks, packetor circuit-switched, are characterized by hybrid architectures. In these architectures, electronic nodes are connected by optical links and switching is usually performed electronically using optoelectronic devices. However, the relatively low transmission bandwidth of the electronics and the associated optoelectronic interfaces, present an obst...
