An optical micro/nanofiber (MNF) is a quasi-one-dimensional free-standing optical
waveguide with a diameter close to or less than the vacuum wavelength of light. Combining …

The conversion-efficiency for second-harmonic (SH) in optical fibers is significantly limited
by extremely weak second-order nonlinearity of fused silica, and pulse pump lasers with …

Recent advances in laser technology demand more-effective measurement of ultrashort
optical pulses in fiber optics and nanophotonics devices. Here we propose an in-fiber …

A widely tunable third-harmonic generation (THG) in a mid-infrared step-index tellurite
optical fiber was investigated in this work. By pumping a 3 cm-long tellurite optical fiber …

Quantum light sources are the core resources for photonics-based quantum information
processing. We investigate the spectral engineering of photon triplets generated by third …
