All-optical data format conversion between RZ and NRZ based on a Mach-Zehnder interferometric wavelength converter
We demonstrate all-optical conversion between two different data formats: return-to-zero (RZ) and nonreturn-to-zero (NRZ) using a Mach-Zehnder interferometric wavelength converter. For RZ-to-NRZExpand

Unbalanced TOAD for optical data and clock separation in self-clocked transparent OTDM networks
We simulate and demonstrate a single-beam intensity-thresholding all-optical switch by modifying a terahertz optical asymmetric demultiplexer (TOAD) with an uneven power splitting in the loop. AnExpand
