Abstract

Singly resonant optical devices are easier to implement and far more stable that their doubly resonant counterparts. However, quantum noise suppression benefits of these extra resonances. In spite of that, singly resonant devices have been proposed for squeezing generation precisely because of this easier implementation. In particular, singly Second Harmonic Generation has been successfully implemented showing a very stable behavior with modest degrees of squeezing at the harmonic mode (R. Paschotta et al. Phys. Rev. Lett. 72. 3807 (1994)). In fact, the maximum theoretically achievable noise suppression is limited in this system to 1/9. Here, we extend the model in order to include phase mismatching between the interacting waves.
