ABSTRACT:
An integrated optical device with a loop resonator is provided, having at least one closed waveguiding loop which has losses. A coupler and at least one input waveguide is coupled to the loop resonator, An adjustment unit controls a coupling coefficient K1of the coupler, and a second coupler is coupled to the loop resonator. At least one output waveguide is coupled with the second coupler to the loop resonator. Another adjustment unit is configured to control coupling coefficient K2of the second coupler, being related to the value of K1, accordingly to the following equation K2=f{K1,ξ}, providing Q{K2}=Max {Q}, where (1−ξ) are the total optical losses within the loop resonator and Q is a resonator characteristic.
