ABSTRACT

WDM networks use high speed MOEMS ring resonators. Due to the substrate loss the regular tuning of the rings is not possible, hence we need a specialized tuning element for the same. As the advantages increases so does the complications and the costs. These difficulties are sparsely overcome by MOEMS technology. The tolerance in fabrication is overcome by embedding the MOEMS actuator with automatic tuning element, this is briefed in this paper. This newly developed fine tuning concept enables the network operator to easily and remotely reconfigure the access network. The catering to various users in the network is made possible by the method. The work focuses on medium carrying multiple wavelength channels (WDM) and supports broadband flexible network infrastructure. The fabrication is done such that the number of channels can be increased at any time, eventually allowing hundreds of channels per chip. By the introduction of auto tuning, the errors and delay in manual adjustments is rather reduced.
