Mid-infrared optical frequency comb generation from a chi-2 optical superlattice box resonator
Kunpeng Jia, Xiaohan Wang, Xin Ni +8
Optical frequency combs (OFCs) at Mid-Infrared (MIR) wavelengths are essential for applications in precise spectroscopy, gas sensing and molecular fingerprinting, because of its re…
Generation of optical frequency comb in a chi-2 sheet micro optical parametric oscillator via cavity phase matching
Xinjie Lv, Xin Ni, Zhenda Xie +7
Chi-3 micro resonators have enabled compact and portable frequency comb generation, but require sophisticated dispersion control. Here we demonstrate an alternative approach using…
Diffraction Interference Induced Superfocusing in Nonlinear Talbot Effect
Dongmei Liu, Yong Zhang, Jianming Wen +6
We report a simple, novel sub-diffraction method, i.e. diffraction interference induced super-focusing in second-harmonic (SH) Talbot effect, to achieve focusing size of less than…
Wave-front engineering by Huygens-Fresnel principle for nonlinear optical interactions in domain engineered structures
Yi-qiang Qin, Chao Zhang, Yong-yuan Zhu
The wave-front engineering for nonlinear optical interactions was discussed. Using Huygens-Fresnel principle we developed a general theory and technique for domain engineering with…
