Generation of Radiation with a Tunable Comb Spectrum in Ring Fiber Cavities Based on Active Photonic Crystal Structures
We consider generation of radiation with a comb spectrum in a ring fiber cavity with harmonic mode locking provided by dissipative four-wave mixing. The main element of the laser system cavity is an amplifying one-dimensional photonic crystal, which combines the properties of an intracavity filter and a power amplifier. Using standard propagation equations describing signal conversion in a ring cavity and an output fiber stage, we demonstrate a possibility of employing the proposed model as a broadband frequency comb generator with a controlled repetition rate of generated signals.
