摘 要
本文利用波長975 nm之雷射二極體及(975±0.5 )nm之布拉格光纖光柵(Fiber Bragg Grating;FBG)所組成之複合式雷射激發摻鉺光纖,以產生波長範圍在1500 nm至1600 nm之寬頻超螢光光源。
摻鉺超螢光光纖光源(Erbium-Doped Superfluorescent Fiber Source;Er-doped SFS)的平均波長有隨溫度變化而漂移的現象,而導航級光纖感測器之光源須為高精度之光纖光源,所以本文利用長週期光纖光柵(Long Period Fiber Grating;LPG)之溫度補償特性,補償光源平均波長因溫度產生之變量,能有效的將光源平均波長對溫度之變異量由(6.2±0.2) pm/°C降至(0.2±0.1) pm/°C,達到穩定光纖光源波長之目的,以符合高精度光纖感測器之需求。
Abstract
In this thesis, we use a hybrid laser to excite the Erbium-doped fiber to form a broadband superfluorescent fiber source (SFS) which region is from 1500 nm to 1600 nm that as a source of high precision fiber optic sensor. And the hybrid laser is a laser diode combined with a fiber Bragg grating (FBG).
The mean wavelength of Erbium-doped superfluorescent fiber source (Er-doped SFS) shifts with temperature. However, it would affect the sensitivity of the fiber optic sensor. For the high precision fiber optic sensor, the source mean wavelength must be with high stability. So we use the temperature compensation characteristic of long period fiber grating (LPG) to compensate for the variation of mean wavelength that shifts by temperature. Now we have reduced the variable that produce by temperature from (6.2±0.2) pm/°C to (0.2±0.1) pm/°C and improved the mean wavelength stability for the fiber source to achieve the requirements for high precision fiber optic sensor.
