As a solution to Fiber to the Home(FTTH),Passive Optical Network(PON)requires a large quantity of passive optical devices,with optical power splitters and wavelength division multiplexers as its key elements.Design and fabrication of multimode Planar Lightwave Circuit(PLC)optical power splitter was carried out. This compact device has low insertion loss,good uniformity and large assembly tolerances,and it’s also insensitive
