Visual observation of optical Floquet-Bloch oscillations
Zhen Zhang, Yuan Li, Xiankai Sun +1
Bloch oscillations, an important transport phenomenon, have extensively been studied in static systems but remain largely unexplored in Floquet systems. Here, we propose a new type…
Comprehensive fabrication of SNAP microresonators by a femtosecond laser
Qi Yu, Zhen Zhang, Xuewen Shu
Surface nanoscale axial photonics (SNAP) microresonators with nanoscale effective radius variation (ERV) along optical fiber axis can be fabricated by inscribing axially oriented l…
Rectangular SNAP microresonator fabricated with a femtosecond laser
Qi Yu, Sajid Zaki, Yong Yang +3
SNAP microresonators, which are fabricated by nanoscale effective radius variation (ERV) of the optical fiber with sub-angstrom precision, can be potentially used as miniature clas…
An optical all-pass filter realized by using self-compensation of loss
Lu Xu, Yuan Yu, Xiaolong Liu +2
Filters are key devices in optical systems and are usually applied to signal suppression or selection based on their amplitude frequency responses. Different from amplitude filteri…
Distributed delay-line interferometer based on a Bragg grating in transmission mode
Miguel A. Preciado, Atalla El-Taher, Xuewen Shu +1
A novel approach for a delay line interferometer (DLI) based purely on forward Bragg scattering is proposed. We have numerically and experimentally demonstrated that a Bragg gratin…
Fabrication of surface nanoscale axial photonics (SNAP) structures with a femtosecond laser
Fangcheng Shen, Xuewen Shu, Lin Zhang +1
Surface nanoscale axial photonics (SNAP) structures are fabricated with a femtosecond laser for the first time. The inscriptions introduced by the laser pressurize the fiber and ca…
