Here we explore the applications of a deformed microdisk as a passive photonic element by coupling it to a bus waveguide. We show that deformed microdisk-based resonant filters are able to have transmittance of more than 99%, and the dropped signals can be routed to two different ports for particular applications. Interestingly, our results show that the splitting ratio can be dynamically tuned by locally changing the refractive index of microdisk. Our research opens new opportunities for the applications of deformed microdisks.
