We present an all-fiber coherent supercontinuum spanning the spectral range of 1.7–5.0 µ m from a cascade of silica, ZBLAN, and chalcogenide (ChG) nonlinear fibers (NLFs). Coherence is maintained by the combined use of femtosecond pump pulses as w

Alloys of sulfur, selenium and tellurium, often referred to as chalcogenide semiconductors, offer a highly versatile, compositionally-controllable material platform for a variety of passive and active photonic applications. They are optically nonline

We demonstrate photonic generation of chirped microwave pulses (CMPs) using an integrated distributed Fabry-Pérot cavity (DFPC) in silicon-on-insulator as a spectral shaper. The DPFC is based on a pair of spatially offset chirped Bragg gratings and

We demonstrate alternate wavelength switching in a widely tunable, dual-wavelength Tm3+-doped fiber laser operating at 1900 nm. A comb filter based on a Sagnac loop incorporating a length of high-birefringence fiber is used to define the lasing wavel

We demonstrate the fabrication and use of a 10-cm-long-PMMA microwire with ultrahigh waveguide nonlinearity γ= 176 W-1 m-1 that is fully compatible with standard single-mode silica fibers. The fabrication of this microtaper is simplified with respec

We present a soliton order preservation mechanism leading to broad tunability with high energy conversion efficiency (ECE) from a fiber-based soliton self-frequency shift (SSFS) system. Here, a pulse compressing fiber, placed before the Raman shiftin
We formulate the energy conversion efficiency from a high-order soliton to fundamental solitons by including the influence of interpulse Raman scattering in the fission process. The proposed analytical formula agrees closely with numerical results of

We report a single-end forward-pumped fiber laser with a record high output power of 3 kW. The laser is assembled exclusively from commercially widespread components such as the Yb-doped fiber with core/cladding diameter of 20/400 µm, pump laser dio

Fiber optical parametric oscillators (FOPOs) are compact optical sources of coherent and broadly tunable light compatible with operation in unconventional spectral bands. Highly nonlinear silica fibers have enabled the development of FOPOs in the tel
