Quantum-controlled cluster states
R. F. Barros, G. B. Alves, O. Pfister +1
Quantum optical cluster states have been increasingly explored, in the light of their importance for measurement-based quantum computing. Here we set forth a new method for generat…
Gouy-phase effects in the frequency combs of an optical parametric oscillator
R. F. Barros, G. B. Alves, A. Z. Khoury
We investigate the transverse mode effects on the frequency combs generated by a type-I optical parametric oscillator (OPO) below threshold. We take the diffraction effects fully i…
Fine-tuning of orbital angular momentum in an optical parametric oscillator
R. F. Barros, G. B. Alves, D. S. Tasca +2
We investigate the dynamical properties of a type-II optical parametric oscillator pumped by a structured light beam carrying orbital angular momentum. Different dynamical regimes…
Conditions for optical parametric oscillation with structured light pump
G. B. Alves, R. F. Barros, D. S. Tasca +2
We investigate the transverse mode structure of the down-converted beams generated by a type-II optical parametric oscillator (OPO) driven by a structured pump. Our analysis focus…
