IEEE Access, Vol 12, Pp 64561-64570 (2024)
A monolithically integrated electronic-photonic Mach-Zehnder modulator is presented, incorporating electronic linear drivers along with photonic components. Electro-optical 3 dB & 6 dB bandwidths of 24 GHz and 34 GHz, respectively, were measured. The

Quantum key distribution (QKD) is nowadays a well-established method for generating secret keys at a distance in an information-theoretically secure way, as the secrecy of QKD relies on the laws of quantum physics and not on computational complexity.

In single crystals of orthorhombic alpha-AlOOH, known also as mineral diaspore, χ(3)-nonlinear lasing by stimulated Raman scattering (SRS) and Raman-induced four-wave mixing (RFWM) is investigated. Picosecond pumping at 1.064 µm wavelength produces

α-LiAlSi2O6, known as mineral spodumene, is introduced as a novel SRS-active crystal with monoclinic symmetry C2/c. Under picosecond laser excitation Raman-induced steady-state χ(3)-nonlinear generation in the visible and near-IR is observed in the
