However, octave-spanning soliton microcombs are challenging to demonstrate on this platform, largely complicated by strong Raman effects hindering reliable fabrication of soliton devices. Here, we demonstrate entirely connected and octave-spanning soliton microcombs on thin-film lithium niobate. With ...
Parametric nonlinear optical processes allow for the generation of new wavelengths of coherent electromagnetic radiation. Their ability to create radiation that is widely tunable in wavelength is particularly appealing, with applications ranging from spe
The OPG spectral tunability from theχ(2)waveguide with birefringence PM is investigated by scanning the pump wavelength in the range of 2.3–2.7 μm. As shown in Fig.4a, pumped at 2.4 μm, a LWIR idler spectrum centered at 8 μm is obtained. When the pump wavelength is increased to 2...
Octave-spanning infrared supercontinuum generation in robust chalcogenide nanotapers using picosecond pulses 来自 掌桥科研 喜欢 0 阅读量: 59 作者:S Shabahang,MP Marquez,G Tao,MU Piracha,AF Abouraddy 摘要: We report on infrared supercontinuum generation extending over more than one octave of ...
To our knowledge, the highest repetition rate obtained with an octave-spanning Ti:Sapphire ring laser, is 2.166 GHz [4]. 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 ...
Microresonator frequency combs can be an enabling technology for optical frequency synthesis and timekeeping in low size, weight, and power architectures. Such systems require comb operation in low-noise, phase-coherent states such as solitons, with broad spectral bandwidths (e.g., octave-spanning)...
A Ti: sapphire oscillator emitting an octave-spanning spectrum that ranges from 460nm to 1000nm is demonstrated. To our knowledge, it is the first time that a supercontinuum extending beyond 500nm in the blue end is generated from a femtosecond oscillato
Octave-spanning frequency comb generation in a silicon nitride chip. We demonstrate a frequency comb spanning an octave via the parametric process of cascaded four-wave mixing in a monolithic, high-Q silicon nitride microrin... Yoshitomo,Okawachi,Kasturi,... - 《Optics Letters》 被引量: 271发...
In this work, we demonstrate the generation of an octave-spanning coherent supercontinuum in a silicon waveguide covering the spectral region from the near- to shortwave-infrared. With input pulses of 18 pJ in energy, the generated signal spans the wavelength range from the edge of the silicon ...
