Low-timing-jitter mode-locked fiber laser based on graphene oxide pva thin film as saturable absorber
We demonstrate a mode-locked fiber laser based on graphene oxide saturable absorber at 1550nm. The laser has a timing jitter of 53fs (100Hz to 100kHz). The contribution from the slow saturable absorber is also investigated.
Simple and compact reflective refractometer based on tilted fiber Bragg grating inscribed in thin-core fiber
A simple and compact reflective refractometer based on a tilted fiber Bragg grating (TFBG) inscribed in an ultra-high photon-sensitive thin-core fiber is proposed and experimentally demonstrated. The reflective refractometer ...
