Abstract

Incoherent broad-bandwidth cw-pumping at λ_p= 1.52 μm a singly resonant Ti:LiNbO₃ integrated optical parametric oscillator at λ_s= 3.94 μm, in the quasi-phase-matched non-degenerate Type I {eee} configuration, may efficiently generate ultra-coherent signal output by the convection-induced phase-locking mechanism. The incoherence of the pump is absorbed by the idler wave at λ_i = 2.47 μm, propagating at the same group velocity v_i=v_p = O.4557c, while the signal propagating at v_s=O.4455c becomes highly coherent. In such an integrated waveguide configuration one obtains signal spectral widths smaller than 5 x 10 ^-4 times the pump spectral width, and a reduction of the average signal intensity fluctuations by less than a factor 10^-4.
