Flexible dispersion engineering using polymer patterning in nanophotonic waveguides
Scientific Reports, 2023 We demonstrate the engineering of waveguide dispersion by lithographically patterning the polymer cladding on silicon nitride waveguide resonators. Both normal and anomalous dispersion, ranging from − 462 to 409 ps/nm/km, can be achieved for the same ...

Optical Precursor of a Single Photon [PDF]
Physical Review Letters, 2011 We report the direct observation of optical precursors of heralded single photons with step- and square-modulated wave packets passing through cold atoms. Using electromagnetically induced transparency and the slow-light effect, we separate the single-photon precursor, which always travels at the speed of light in vacuum, from its delayed main wave ...

Hyperspectral screen-image-synthesis meter with scattering-noise suppression
Scientific Reports, 2023 The screen image synthesis (SIS) meter was originally proposed as a high-speed measurement tool, which fused the measured data from multiple sample-rotational angles to produce a whole-field measurement result. However, it suffered from stray light noise

Femtosecond tunable solitons up to 4.8 µm using soliton self-frequency shift in an InF3 fiber
Scientific Reports, 2022 A tunable ultrashort soliton pulse source reaching up to 4.8 µm is demonstrated based on a 2.8 µm femtosecond fiber laser coupled to a zirconium fluoride fiber amplifier followed by a small core indium fluoride fiber.
