Optimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications

We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

Folded Architecture for Modular All-optical Switch

Optical switches are necessary for achieving reliable, fast and flexible modular communication means in future systems. Free space approaches are advantageous since they fully use the two dimensions optics offer. A folded architecture based on a polarization code is proposed for optical switching. The suggested system is compact and appropriate for both intraand intercomputer communication. The...

All-optical compact silicon comb switch.

We demonstrate a 1x2 all-optical comb switch using a 200 mum diameter silicon ring resonator with a switching time of less than 1 ns. The switch overcomes the small bandwidth of the traditional ring resonator, and works for wavelength division multiplexing applications. The device has a footprint of ~0.04 mm(2) and enables switching of a large number (~40) of wavelength channels spaced by ~0.85...
