Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches...

We demonstrated a 1 4 all-optical packet switch with all-optical header processing at a header rate of 5 Gb/s and payload rate of 10 Gb/s using injection-locking in a single Fabry–Pérot laser diode at each output port of the switch.

We present a detailed time-domain analysis of a promising nonlinear optical device consisting of alternating layers of nonlinear materials with oppositely signed Kerr coefficients. We study propagation of nonsolitonic (Gaussian) pulses through the device, whose transmittance characteristics point to potential uses in all-optical switches and limiters. If the optical structure has no linear buil...

We demonstrate a novel all-optical switch based on frequency upconversion. The switch features advantages for telecommunications: it is fast, transparent, frequency-multiplexable and bias-free.

FAST ELECTRONIC DRIVER FOR OPTICAL SWITCHES Electronically controlled optical switches are critical components in many optical systems, including pulsed lasers. Solid-state optical switches based upon the Pockels effect are widely utilized in research and industry, however Pockels cells require electronic drivers capable of switching several kilovolts quickly and cleanly. This thesis reviews Po...

We propose and analyse a GaAs-based optical switch having a ring resonator configuration which can switch optical telecommunication signals over the 1300 nm and 1500 nm bands, using bias assisted carrier injection as the switching mechanism. The switching is achieved through variation in the refractive index of the ring resonator produced by changing the injected carrier density through the app...

Recently, optical packet switch architectures, composed of devices such as optical switches, fiber delay lines, and passive couplers, have been proposed to overcome the electromagnetic interference (EMI), pinout and interconnection problems that would be encountered in future large electronic switch cores. However, attaining the buffer size (buffer depth) in optical packet switches required in ...

We propose and demonstrate a port-alternated switch-and-select architecture for planar waveguide-based optical switches. The proposed reduces the number of intersections on path, which leads to both small insertion loss path dependence. an 8 × switch based using silicon photonic platform, exhibits fiber-to-fiber 5.7 dB with crosstalk below -30 dB. discuss scalability switch, including propagati...

We review recent theoretical and experimental efforts toward developing an all-optical switch based on transverse optical patterns. Transverse optical patterns are formed when counterpropagating laser beams interact with a nonlinear medium. A perturbation, in the form of a weak switch beam injected into the nonlinear medium, controls the orientation of the generated patterns. Each state of the ...
