A Ti:sapphire oscillator emitting an octave-spanning spectrum that ranges from 460 to 1000 nm is demonstrated. To our knowledge, it is the first time that a supercontinuum as a whole measured after the Output coupler extending beyond 500 nm in the blue end is generated from a femtosecond Ti...

We demonstrate a prism-based pulse shaping setup that enables the shaping of ultrashort pulses with octave-spanning spectra. In contrast to gratings prisms allow for a high throughput and large bandwidths. The second-order dispersion of the prism material is precompensated by a fused silica prism...
spectrum remains challenging. Here we take a different approach to spectral broadening of mid-infrared frequency combs and investigate CMOS-compatible highly nonlinear dispersion-engineered silicon nanophotonic waveguides on a silicon-on-insulator chip. We record octave-spanning (1,500–3,300 nm) ...
Octave-spanning spectrum of femtosecond Yb:fiber ring laser at 528 MHz repetition rate in microstructured tellurite fiber The octave-spanning spectrum was generated in a tellurite glass based microstructured fiber pumped by a 528 MHz repetition rate Yb:fiber ring laser without...

The octave-spanning spectrum is generated by reducing the repetition rate of a microcomb from its initial repetition rate of 25.6 GHz using a pulse picking setup that transmits every n-th pulse with an electro-optic modulator. This generates pulse trains with repetition rates between 20 MHz and...

Here, using specially designed optical fibers that support OAM modes whose group velocity can be tailored, we demonstrate Raman solitons in OAM modes as well as the first supercontinuum spanning more than an octave (630 nm to 1430 nm), with the entire spectrum in the same polarization as well...
