An important goal for microcombs is self-referencing, which requires octave-spanning bandwidths to detect and stabilize the comb carrier envelope offset frequency. Further, detection and locking of the comb spacings are often achieved using frequency division by electro-optic modulation. The thin-film...
aCalculated normalized gain spectrum at a pump wavelength of 2.4 μm for a bulk ZnGeP2(ZGP) crystal, at various phase match (PM) angles. A PM angle ofθ = 48.3° is designed as marked by the orange dashed line to generate the broadest gain bandwidth.bSimulated electric field distrib...
We report on infrared supercontinuum generation extending over more than one octave of bandwidth, from 850nm to 2.35μm, produced in a single spatial mode from a robust, compact, composite chalcogenide glass nanotaper. A picosecond laser at 1.55μm pumps a high-index-contrast, all-solid nanota...
The obstacle posed by TPA has indeed pushed octave-spanning SC research into the long wavelength region23–27. For example, octave- spanning SC in SOI has been demonstrated in the shortwave infrared (SWIR)23 (−30 dB bandwidth), albeit with absorption losses beyond 2.5 μm in the presence...
Octave-spanning spectra directly from a two-foci Ti:sapphire laser with enhanced self-phase modulation Recent efforts in this field provided pulses in the two-cycle regime with bandwidths below one octave. In our work we refined the intracavity approach ... R Ell,U Morgner,F Krtner,... -...
Full tunability of the generated frequency comb over a bandwidth exceeding an entire free spectral range is demonstrated. This allows positioning of a frequency comb mode to any desired frequency within the comb bandwidth. The ability to derive octave spanning spectra from microresonator comb generators...
Here we report the achievement of a 4.3 GHz octave-spanning laser frequency comb.To achieve an octave at the direct output of the laser, optimization of the different elements of the cavity is required. A combination of broad bandwidth chirped mirrors and an additional fused silica plate are ...

Usually, the efficiency and bandwidth of the resonant process are interdependent due to stringent phase matching requirements leading to limitation of the bandwidth of the spectrum generated for a given pump power. We demonstrate a continuous-wave low-threshold resonant optical parametric oscillator with...
