An all-optical modulator based on graphene-photonic crystal fiber (G-PCF) is demonstrated, and the G-PCF is fabricated by directly growing graphene onto inner hole walls of the photonic crystal fiber (PCF) with atmospheric pressure chemical vapor deposition (APCVD). A 1550 nm pump laser is used to induce all-optical intensity modulation of probe light. A G-PCF with a length of 2 cm achieves a significant modulation depth of 2.58 dB under a low pump power of 60 mW at wavelength of 895 nm. The flexible structure and all-optical control enable the G-PCF to have great potential in all-optical devices and photonics.

基于石墨烯-光子晶体光纤的全光调制器

展示了一种基于石墨烯-光子晶体光纤（G-PCF）的全光调制器，通过常压化学气相沉积将石墨烯直接生长到光子晶体光纤（PCF）的内孔壁上来制造G-PCF。 APCVD）。1550 nm 泵浦激光器用于诱导探测光的全光强度调制。长度为 2 cm 的 G-PCF 在 60 mW 的低泵浦功率下在 895 nm 波长下实现了 2.58 dB 的显着调制深度。灵活的结构和全光控制使G-PCF在全光器件和光子学方面具有巨大的潜力。
