We experimentally demonstrate a 10 times enhancement to the coincidence-to-accidental ratio of a correlated photon-pair source from a chalcogenide Ge11.5As24Se64.5 nanowire. This improvement is enabled by the low-Raman window of the device.
Birefringence in poled fiber enables the direct (compensation-free) generation of broadband polarization-entangled photon pairs. However, birefringence and pump detuning also affect the entangled state, a subject we investigate in this work theoretically and experimentally.
We demonstrate a topological transition in the iso-frequency surface of a strongly anisotropic metamaterial and show the potential of this optical topological transition for controlling light-matter interaction.
We demonstrate that the longevity of an optical filament can be drastically increased by prudently surrounding it with a low intensity annular wavefront. Here, we systematically study the dynamics and robustness of such dressed filaments.
Femtosecond Tm-fiber-laser-pumped Ho:YAG room-temperature CPA system delivering scalable multi-mJ multi-kHz pulses with a bandwidth exceeding 12 nm and the average power of 15 W is developed. Recompressed 530-fs pulses are suitable for broadband WL generation in transparent solids.
Aqueous suspensions containing pure gold nanoparticles and silica-gold core-shells are shown to exhibit different polarizibilities, thus allowing self-trapping of long needles of light. The different nonlinear mechanisms behind these processes are investigated.
