Q-factor in optical resonators is important issue that quality the device and the type of applications. Due to the advantages of optical resonators in terms of reproducibility on chip (that are designed of various topologies and integration with optical devices), it is very important to get a highest Qfactor. To increase this factor from the lower rang [10⁴ - 10⁶] to higher one [10⁸ -10¹⁰] we use crystalline resonators. In practice, it is more complicated to couple an optical signal from a tapered fiber to crystalline resonator than from a defined ridge to a resonator designed on a chip. In this work, we will focus on the simulation and optimization of the crystalline resonators under straight wave guide and subject also to technological constraints of manufacturing. The coupling problem at the Nano scale makes our optimizations problem more dynamics in term of design space.
