The MUFINS project aimed to develop arrays of generic optical switches integrated on a single chip, and to prove their multi-functional nature by using them to implement token all-optical circuits. The integration of arrays of generic switches will significantly reduce the cost per switch, and will initiate efforts for production of multiple optical switches on a single chip. Indeed, MUFINS succeded in all its objectives and succesfully completed the following:

  1. Development of monolithically integrated, packaged and pigtailed, 2- and 4- element, 10 and 40 Gb/s, 2x2 optical switch arrays, using (a) active/passive integration based on regrowth and (b) Active Vertical Coupler (AVC) platforms, and development of hybridly integrated, packaged and pigtailed, 4- element, 40 Gb/s, 2x2 optical switch arrays.
  2. Evaluation of the switch arrays performance and their multi-functional potential in token optical network applications at 10 and 40 Gb/s (Header Extraction, Half Adder, Time Slot Interchanger and Full Adder circuit at 10 Gb/s; Clock and Data Recovery (CDR), Data Vortex switch and 4x4 Switching Matrix at 40 Gb/s; finally, 4-wavelength, all-optical Burst Mode Receiver at 10 Gb/s, incorporating twelve (12) SOA-MZI gates).
  3. Development and evaluation of two (2) 40 Gb/s, integrated, all-optical structures, namely a hybrid Burst Mode Receiver and a monolithic Clock and Data Recovery.
