Experimental Investigation of Multi-mode Fiber Laser Cutting of Cement Mortar [PDF]
Materials (Basel), 2018 This study successfully applied multi-mode laser cutting with the variation of the laser cutting speed to cement mortar for the first time. The effects of the amount of silica sand in the cement mortar on laser cutting are tested and analyzed.

Design of flexible multi-mode fiber endoscope.
Optics Express, 2015 Multi-mode fiber (MMF) endoscopes are extremely thin and have higher spatial resolution than conventional endoscopes; however, all current MMF endoscope designs require either that the MMF remain rigid during insertion and imaging or that the orientation

Ultra-thin rigid endoscope: Two-photon imaging through a graded-index multi-mode fiber [PDF]
Optics Express, 2015 Rigid endoscopes like graded-index (GRIN) lenses are known tools in biological imaging, but it is conceptually difficult to miniaturize them. In this letter, we demonstrate an ultra-thin rigid endoscope with a diameter of only 125 microns.

Efficient mode coupling between a few-mode fiber and multi-mode photonic chip with low crosstalk.
Optics Express, 2022 The mode-division multiplexing technology has been developing slowly in the field of fiber-chip-fiber optical interconnects, mainly limited by the inefficient mode coupling between few-mode fiber and multi-mode photonic chip. Here we propose and design a
