▲ [7a-PA5-10] 3D Printed Mechanically Induced Long-Period Fiber Grating for Power Attenuation
キーワード:long-period fiber grating, mechanically induced LPFG
A long-period fiber grating (LPFG) has a key ability of mode coupling from fundamental core mode to cladding modes. This can be beneficially used as a fiber optic filter. Mechanically induced LPFG has been developed in recent years for simpler technique comparing with other methods i.e. irradiation by CO2 lasers, arc discharge, and etching discharge. In addition, there are several types of mechanically induced LPFGs. This paper presents the novel 3D printed mechanically induced LPFG, that is printed by a translucent and hard material called RGD720. This mechanically induced LPFG is directly pushed on to the fiber as perturbation point to attenuate the power.
