Abstract: High-stability doughnut beams propagating in the fibers are characterized as high-order modes, which have been widely exploited for optical tweezers, high-capacity fiber communication, and precision metrology. We experimentally demonstrate bending-insensitive doughnut beam generation based on… read more here.
