Continuously Tuneable MZI-based Delay Line Overcoming Delay-Bandwidth Product

A silicon photonic integrated circuit, implementing a novel delay-line architecture, is proposed. The device, based on a set of four nested Mach-Zehnder Interferometers, overcomes typical delay-bandwidth product. Showing a minimum bandwidth of 20 GHz, group delay can be continuously tuned between 0...

Summary:A silicon photonic integrated circuit, implementing a novel delay-line architecture, is proposed. The device, based on a set of four nested Mach-Zehnder Interferometers, overcomes typical delay-bandwidth product. Showing a minimum bandwidth of 20 GHz, group delay can be continuously tuned between 0 and 100 ps.
