Summary: In this study, a pulse characterization scheme is introduced to characterize ultrafast pulses at the single-photon level without the need for nonlinear effects. The method utilizes controlled time and frequency shifts implemented via an electro-optic modulator for fully-electronic experimental control. The full spectral and temporal width of classical and single-photon-level pulses is successfully characterized.

Summary: In this work, electro-optically controlled optical metasurfaces for reflection modulation are demonstrated. By identifying a suitable low-loss waveguide mode and exploiting its resonant excitation, the modulation of reflected light power with superior characteristics is achieved compared to previous research. The electro-optic Pockels effect in a 300 nm-thick lithium niobate (LN) film is utilized to realize fast and efficient light modulation.

Summary: Electro-optic modulation, an important topic in the field of communications and sensing, faces limitations in increasing modulation efficiency due to the monotonic mapping relationship between electrical and optical signals. To overcome this limitation, researchers reveal a new mechanism called phase-transition EO modulation, achieved through the reciprocal transition between distinct phase planes. An integrated mode-locked laser prototype is implemented, achieving an ultrahigh modulation energy efficiency and a high contrast ratio, with applications in radio-over-fiber communication and acoustic sensing. This advancement in EO modulation technology opens up new possibilities for green communication and ubiquitous sensing.

Summary: Entangling microwave-frequency superconducting quantum processors through optical light at ambient temperature would enable secure communication and distributed quantum information processing. However, transducing quantum signals between these disparate regimes of the electro-magnetic spectrum remains an outstanding goal, and interfacing superconducting qubits with electro-optic transducers presents considerable challenges. In this study, a low-backaction electro-optomechanical transducer is used to readout a superconducting transmon qubit. The modular nature of the transducer and circuit quantum electrodynamics system enable complete isolation of the qubit from optical photons, with minimal backaction on the qubit. Improvements in the transducer bandwidth and noise levels will enable the transduction of non-classical signals from a superconducting qubit to the optical domain.

Summary: Phase gradient metasurfaces have transformed modern optical components by reducing path length while maintaining high performance. However, their geometric design poses challenges for dynamic modulation, with devices needing to balance modulation range and efficiency. Silicon-on-Lithium Niobate (LNO) high-Q metasurfaces offer efficient electro-optic wavefront shaping and modulation through periodic perturbations and high-Q resonances.

Summary: This study presents flat-topped coherent supercontinuum lasers with tunable repetition rates and programmable spectral bandwidths. By merging nonlinearly broadened electro-optic optical frequency combs with optical line-by-line spectrum shaping, supercontinuum sources with ultra-broadband and high-repetition-rate coverage can be achieved. The spectral bandwidth programming is implemented by iterative spectrum shaping and input power control, while the repetition rate tuning is performed by modulation speed control. The coherence of the supercontinuum during tuning and programming is analyzed using a phase-noise analysis method.
