Dense Wavelength Devision Multiplexing (DWDM) is the most promising technology
to supply the huge bandwidth demand for the Internet. In DWDM, multiple optical
signals are combined in a single fiber by transmitting each signal at different
wavelength. The network capacity is therefore scaled with the number of wavelength
channels. A major challenge for DWDM is to optically switch the different wavelength
channels at the network node without employing bandwidth-limiting optical-to-electrical-to-optical
This project investigated active micro photonic integrated circuits that are tunable,
leveraging on the microelectronics silicon-on-insulator (SOI) CMOS technology.
We designed, modelled and fabricated compact integrated photonic DWDM channel-drop
filters using passive optical micro-resonators. SOI micro-ring and micro-disk
resonators coupled with sub-micron waveguides has been demonstrated.
We also designed and fabricated SOI integrated optical switches
and modulators using active electro-optically tunable optical micro-resonators.
