Abstract

A single-mode cw optical parametric oscillator (OPO) based on a bulk Bragg grating is reported. The OPO is capable of producing multiwatt output power both at the signal $\left(1535\mathrm{nm}\right)$ and idler $\left(3468\mathrm{nm}\right)$ wavelengths with a side-mode suppression ratio better than $29\mathrm{dB}$. Coarse frequency tuning of $120\mathrm{GHz}$ $\left(4{\mathrm{cm}}^{-1}\right)$ and fast mode-hop-free tuning of $40\mathrm{GHz}$ $\left(1.3{\mathrm{cm}}^{-1}\right)$ have been achieved by scanning the grating temperature and the OPO pump laser, respectively.
