TL;DR: The first handedness control of an optical vortex output from a vortex-pumped optical parametric oscillator and it is found that the handedness of a fractional vortex with a half integer topological charge can also be selectively controlled.
Abstract: We present the first handedness control of an optical vortex output from a vortex-pumped optical parametric oscillator. The handedness of the optical vortex was identical to that of the pump vortex beam. Over 2 mJ, 2-μm optical vortex with a topological charge of ± 1 was achieved. We found that the handedness of a fractional vortex with a half integer topological charge can also be selectively controlled.

TL;DR: In this paper, a non-linear circuit with integrated Mach-Zehnder interferometers on LiNbO 3 was analyzed by the describing function technique, and the conditions for stable oscillations and oscillator synchronization were well confirmed by experiments.

TL;DR: In this article, a coplanar waveguide ferromagnetic parametric amplifier fabricated on a Ferromagnetic Permalloy thin film has been reported with a power gain of 4 dB at 1.15 GHz when the pump power is 11.1 dBm at the pump frequency of 2.30 GHz under the bias field of 13 Oe.
Abstract: In this letter, we report a coplanar waveguide ferromagnetic parametric amplifier fabricated on a ferromagnetic Permalloy thin film. It shows a power gain of 4 dB at 1.15 GHz when the pump power is 11.1 dBm at the pump frequency of 2.30 GHz under the bias field of 13 Oe. This prototype ferromagnetic device can be integrated with the complementary metal-oxide semiconductor process technology and has potential applications as a spin-wave amplifier, a low noise amplifier, or an active bandpass filter.

TL;DR: Efficient generation of new spectral components owing to second-order cascading in a seeded broadband beta -barium borate typeI phase-matching parametric amplifier is demonstrated.
Abstract: Efficient generation of new spectral components owing to second-order cascading in a seeded broadband β-barium borate type I phase-matching parametric amplifier is demonstrated. One can vary the number and magnitude of these components by changing amplification bandwidth (wavelength) and phase-matching conditions. The phenomenon is treated theoretically by use of a formalism developed previously for the case of cascaded self-diffraction.
