Design optimization of band-pass filter based on parity-time symmetry coupled-resonant

Autor: Lu, Xinda, Chen, Nuo, Zhang, Boqing, Yang, Haofan, Chen, Yuntian, Zhang, Xinliang, Xu, Jing

Integrated optical filter based on microring resonators plays a critical role in many applications, ranging from wavelength division multiplexing and switching to channel routing. Bandwidth tunable filters are capable of meeting the on-demand flexibl

Stability analysis of generalized Lugiato-Lefever equation with lumped filter for Kerr optical soliton generation in anomalous dispersion regime

Autor: Chen, Nuo, Zhang, Boqing, Yang, Haofan, Lu, Xinda, He, Shiqi, Hu, Yuhang, Chen, Yuntian, Zhang, Xinliang, Xu, Jing

We raise a detuning-dependent loss mechanism to describe the soliton formation dynamics when the lumped filtering operation is manipulated in anomalous group velocity dispersion regime, using stability analysis of generalized Lugiato-Lefever equation

Second harmonic generation in modal phase-matched AlGaAs-on-insulator waveguides

Autor: Lu Xinda, Zheng Yi, Ye Chaochao, Yvind Kresten, Pu Minhao

Publikováno v: EPJ Web of Conferences, Vol 287, p 06006 (2023)

We utilize modal phase matching and type-I configuration to achieve second harmonic generation in AlGaAs-on-insulator waveguides. We demonstrate an overall normalized conversion efficiency of 200% W-1 cm-2 at a pump wavelength of 1587 nm in a 1-mm-lo
