We report the generation and coincidence-to-accidental ratio characterization of a pulsed spontaneous parametric down-conversion photon pair source at 2.080 µm, as a basis for free-space quantum communication in an atmospheric window with low solar background.

The pulse timing between polarization-maintaining Er- and Yb-doped mode-locked fiber lasers was passively stabilized by an all-optical synchronization scheme based on nonlinear amplifying loop mirror, showing a cavity mismatch tolerance up to 16.2 mm.

We demonstrate coupling of mechanical mode of graphene resonator to that of Silicon Nitride resonator, resulting in 38 dB gain. Furthermore, with thermomechanical squeezing of graphene thermal noise, we demonstrate an overall measurement sensitivity of 3.8 fmHz−1/2.

We investigate the saturable absorption of hybrid graphene/silicon-nitride waveguides at telecom wavelengths. By measuring the power dependent transmission of picosecond and sub-picosecond pulses, we clarify the temporal dynamics of photo-excited carriers in graphene.

Brunel harmonics appear in gases due to tunnel ionization of electrons in strong fields (without recollision with the cores). Here we extend this mechanism to nanos-tructures. The harmonics are affected by strong field gradients.

By applying an external electric field to CQDs, we have demonstrated tunable amplified spontaneous emission (ASE) threshold in a long-sought practical device. Our results open new possibilities for achieving zero-threshold and electrically pumped CQD lasers.
