NFt Thermo-Capillary Optical Switch Thermo -Capillary Optical Switch Fuge Olive switch is a novel sub-millimeter-size optical switch realized by combining MEMS technology with PLC technology. Olive switch has high optical transparency and a high On/Off ratio in addition to belng mechanically self-latching. CMive switch: Oil laiching bipe interfacial tension variation effect switch MEMS: Micro electro mechanical systems PLC: Planer lightwave circuit Features Applications BB Low crosstalk B Space division switching syslems @ Low PDLk BB Cross-connect and add-drop for WOM B Low 4 dependence loss B Protective switching Bf Low power consumpbliane BF Inter-conmectian @ Small scale factor @ High reliability upper substrate Ole switch congests of slitted intersecting wavequides, 4 micro heaters aan pair ol micro-heaters, and index matching oil in the slit. slit sont Ss 0 transmit When the surface tension af the oil i decreased by heal: ing, the oll column moves in the slit towards the lower lemperature side because of thermo-capillary force, When the all is away from the cross paint of the wave- guides the light path is switched by total intemal reflec on on the slit side wall With integrating miuttipss Olive switch elements, 1xN selector and MxN matrix switch are made.
