Multi – Functional In tegrated Arrays of Interferometric Switches
[September 2004 – August 2007]

The MUFINS project aimed to take the next logical step in the evolution of all-optical signal processing, to integrate multiple switching elements on a single chip, and to interconnect these integrated switching elements into functional logic modules with the aid of a external components. 2×2 Mach Zehnder Interferometers that operate as all-optical switches were fabricated as two and four element integrated arrays. These switches were used as the main building blocks for the development of a wide range of functionalsubsystems, such as Header Extraction, Half Adder, Full Adder, Time Slot Interchanger, Clock and Data Recovery, Data Vortex Switch, 4×4 Switching Matrix, all- optical 4-wavelength Burst Mode Receiver, 40 Gb/s all-optical Burst Mode Receiver.
