Modeling and simulation of a singly resonant fiber optical parametric oscillator

So far, the commonly used optical parametric oscillators (OPOs) relying on chi((2)) nonlinearity in the bulk materials have been extensively investigated both theoretically and experimentally, but not enough attention has been paid to OPOs based on chi((3)) nonlinearity in optical fibers. In this paper, a singly resonant fiber optical parametric oscillator (FOPO) is theoretically studied and its main aspects are simulated. Also, impacts of various parameters including the pump and signal wavelengths, the fiber length and dispersion as well as the input coupler on the conversion efficiency of the FOPO are investigated. Finally, the simulation results are compared with the available experimental data and a very good agreement is obtained.
