Reconfigurable SDM Switching Using Novel Silicon Photonic Integrated Circuit

Space division multiplexing using multicore fibers is becoming a more and more promising technology. In space-division multiplexing fiber network, the reconfigurable switch is one of the most critical components in network nodes. In this paper we for the first time demonstrate reconfigurable space-division multiplexing switching using silicon photonic integrated circuit, which is fabricated on ...

Integrated Optical Waveguide Device for Picosecond Pulse Compression

We report on the fabrication and characterization of a new device, named IRIS. It is designed to increase the coherent optical bandwidth of a picosecond pulse train for subsequent pulse compression. The IRIS device consists of a concatenated array of semiconductor optical amplifiers and saturable absorbers. It is realized in the InP/InGaAsP material system for the 1550 nm range. Measurements on...

Multi-format all-optical processing based on a large-scale, hybridly integrated photonic circuit.

We investigate through numerical studies and experiments the performance of a large scale, silica-on-silicon photonic integrated circuit for multi-format regeneration and wavelength-conversion. The circuit encompasses a monolithically integrated array of four SOAs inside two parallel Mach-Zehnder structures, four delay interferometers and a large number of silica waveguides and couplers. Exploi...
