Optical frequency comb in optoelectronic oscillator with delay line and microresonator

We proposed and studied a new method which allows producing an optical frequency comb in an optoelectronic oscillator. In this method, comb parameters can be adjusted by controlling CW laser and microwave filter frequencies and amplitudes of modulating signals supplied to the arms of Mach-Zehnder modulator having two separate microwave inputs. Characteristics of the system were studied with numerical modeling for delay line and mictoresonator in the optoelectronic oscillator loop.
