An all-optical clock recovery has been demonstrated numerically with single and double ring microring resonators from 40 Gbit/s return-to-zero on-off keying optical signal. The influence of device cascadability on amplitude fluctuation caused by patterning effects of extracted clock values have been evaluated. Open source simulation toolbox Optilux was used for simulations. The results show that these fluctuations related to patterning effects are considerably reduced after processing with five cascaded single ring microring resonators.
