Summary: In this study, nonlinear optical effects in electron systems with and without inversion symmetry in a Fabry-Perot cavity are investigated. The coupling of a noninteracting lattice model to two modes of the quantized light field is used to model general photon up- and down-conversion processes. Truncated models are shown to capture correlation effects induced by photons in the electronic subsystem despite their small Hilbert space.

Summary: Solid-state single photon emitters (SPEs) in atomically thin transition metal dichalcogenides (TMDs) have gained attention as scalable quantum light sources. In this study, strain fields were created in WSe2 monolayers (MLs) using nanoparticle (NP) arrays, leading to the formation of isolatable SPEs. The emission spectra of WSe2 MLs were quantified to provide insight into the mechanism for SPE production. Excitons selectively funneled through strongly coupled sub-bandgap states, resulting in anti-bunched behavior.

Summary: The feasibility of nonreciprocal photonic devices in the quantum world has been investigated. A single-photon non-reciprocal dynamical transmission experiment using an on-chip silicon nitride-based magneto-optical isolator has been performed, achieving a measured isolation ratio of 12.33 dB. The functionality of the on-chip isolator has been proven, and the quantum coherence of the passing single photons has been verified. This work will contribute to the development of on-chip nonreciprocal photonic devices within integrated quantum circuits and introduce novel phenomena in quantum information processes.

Summary: Cavity quantum optomechanics is a new platform for quantum science and technology that has various applications. This work introduces a pulsed approach to generate and verify non-Gaussian states of motion using the nonlinearity of the radiation-pressure interaction and photon-counting measurements. The authors also propose a protocol to measure the quadrature moments of the two mechanical oscillators using pulsed interactions, allowing for experimental characterization of bipartite mechanical quantum states. This scheme provides a new avenue for quantum experiments with entangled mechanical oscillators and has significant potential for quantum-information and sensing applications, as well as studying the quantum-to-classical transition.

Summary: By demonstrating precise control over individual photons, the study shows controlled multi-photon subtraction in a tightly confined cold atom ensemble, revealing that excitation blockade between Rydberg atoms limits photon absorption and rapid dephasing suppresses stimulated re-emission.

Summary: This paper reports GaNOI microresonators with intrinsic quality factors over 2.5 million, corresponding to an optical loss of 0.17 dB cm(-1). It demonstrates a parametric oscillation threshold power as low as 6.2 mW and estimates the experimentally extracted nonlinear index of GaN at telecom wavelengths to be n(2) = 1.4 x 10(-18) m(2) W-1, which is several times larger than that of commonly used platforms such as Si3N4, LiNbO3, and AlN. The large intrinsic nonlinear refractive index, together with its broadband transparency window and high refractive index contrast, make GaNOI a promising platform for chip-scale nonlinear applications.

Summary: The intentional inclusion of key atomic elements in purpose-designed glass allows for unprecedented control over ultrafast laser written circular waveguide morphology and refractive index change. Factors such as viscosity, aluminum to alkaline earth+alkali ratio, and total silicon content within the glass are crucial in producing waveguides with high circularity and refractive index change. Drawing on this knowledge, a designer glass has been successfully fabricated to maintain circular waveguide morphology, high refractive index, and amorphous composition even at fast feed rates.

Summary: This paper investigates the performance of a Brillouin-based isolation scheme in a traditional ridge waveguide. The study finds that acoustic confinement and Brillouin-driven mode conversion can be enhanced by selecting appropriate optical mode pairs and waveguide geometries. By optimizing the entire isolator design, including input couplers, mode filters, Brillouin-active waveguides, and device fabrication tolerances, it is predicted that the device can achieve 30 dB isolation over a 38 nm bandwidth with 500 mW pump power. In the presence of a +/- 10 nm fabrication-induced width error, such isolation can be maintained over a 5-10 nm bandwidth.

Summary: Microwave photonics provides a promising solution for frequency converting microwave signals. In this study, a chip-based stimulated Brillouin scattering and interferometry technique is used to demonstrate the first microwave photonic mixer with image rejection of broadband signals. The mixer achieves frequency down-conversion of carrier frequencies ranging from 10 GHz-16 GHz, ultra-high image rejection for single tone signals up to 70 dB, and image rejection of 28.5 dB and 16 dB for 100 MHz and 400 MHz wide analogue signals, respectively. Furthermore, the mixer successfully down-converts 200 Mb/s quadrature-phase-shift keying signals with a low error vector magnitude of -9.6 dB, even when there are interfering image signals present.

Summary: This paper presents the first experimental observation of reversible 1550 nm-induced Bragg gratings and stimulated Brillouin scattering (SBS) in a planar waveguide made of high-index chalcogenide material, arsenic triselenide (As2Se3). The temporary grating is inscribed by the two-photon absorption (TPA)-induced refractive index change along the waveguide, facilitated by the high Fresnel reflection from the chip facet. The SBS measurements reveal the Brillouin gain coefficient and frequency shift values, and the investigation explains the observed broadening of the linewidth due to the photorefractive effect in the waveguide.
