Abstract

The microdisk based devices principle of operation is presented. The advantages of analytical approach to design with accuracy this kind of structure are discussed. Problems caused by a random roughness on the microdisk periphery are also introduced. It is also shown that a periodic roughness such as a microgear structure can significantly increase the quality factor for some specifically chosen modes. Different design to extract the light from the resonator are presented. The case of a microdisk and waveguide output coupler is better developed. Through new analytical modeling based on perturbation theory, the effect of the interaction between a channel waveguide and a microdisk is indeed presented showing a fast and efficient approach to design such couplers.
