Complete small signal equivalent circuit model of 10Gb/s TOSA package EML module

A complete high frequency small signal equivalent circuit model of 10Gb/s TOSA package of Electroabsorption Modulator integrated Laser(EML) is presented. The model includes submount, bonding wires, flexible printed circuit (FPC), and EML chip. The values of each component parameters are extracted by the method of curve fitting. A good agreement between measured and simulated results confirms the accuracy and valid the procedures. It is expected that the low-cost TOSA packaged EML module and good E/O response characteristic can be achieved using the proposed model.
