We have developed a demultiplexer known as a Colliding Pulse Mach- Zehnder (CPMZ) suitable for OTDM systems capable of ultrafast all- optical demultiplexing and address recognition. Recently we have demonstrated a polarization and wavelength independent device, called a Terabit Optical Demultiplexer, which is capable of all-optical demultiplexing of Tbit/s pulse train with 650 fJ of switching energy, and which can be integrated on a chip. This device has achieved a 10 ps switching window. Both devices are wavelength compatible with all of the low loss transmission windows of optical fibers.
