Even so, the instability sometimes accompanied by mode hoping of the lasing wavelength of the fgesl, and the instability of output power have been experimentally observed. the objective of this work is just to explain these experimental phenomena and explore the physical mechanism hidden in these phenomena
盡管fgesl具有這些優點，但是由於其本質上還是屬于外腔激光器，因此仍具有外腔激光器通常存在的激射波長不穩定、跳模及輸出功率不穩定等現象。 -
( 3 ) with the increase of the injected current, the lasing wavelength of fgesl appears fluctuation, the side mode suppression ratio ( smsr ) increases accompanied by an oscillation, and the p - i curve distorts slightly
Fgesl的激射波長隨ld的注入電流的增大而發生波動;邊模抑制比（ smsr ）隨注入電流的增大總體上呈現上升趨勢，但其變化過程並不平滑而是有較大的波動; fgesl的p一i曲線有微小的扭曲。 -
The work mechanism of the novel laser is introduced, and the math expression of efficiency is given, and the lasing mode and the distribution of the optical field are simulated. it proves that for the novel laser, the inner quantum efficiency is larger than l, and at the same injecting current compared with the normal laser ; the output optical power is higher

In this work, based on the threshold condition of the fiber grating external cavity semiconductor laser ( fgesl ) which the phase of the fiber grating has been included, the effect of the temperature variation and the fg external cavity length on the lasing wavelength of the fgesl has been investigated theoretically. in addition, we have used the phase condition of fgesl to get the longitudinal mode distribution of fgesl, then the influence of the injected current on the output characteristics of fgesl has been studied
基於此，本文中利用陽實際的反射相位分佈，計及半導體激光器（ ld ） 、外腔及光纖光柵（ fg ）三者的共同作用，根據fgesl滿足的閩值條件，從理論上研究了溫度及外腔長度的變化對fgesl激射波長的影響;根據fgesl中縱模所滿足的相位條件得到其縱模分佈后，利用fgesl滿足的多模速率方程，研究了ld的注入電流對fgesl輸出特性的影響。 -
Numerical simulations show that : ( 1 ) owing to the temperature variation resulting in the change of the refractive index of both the semiconductor medium and the fi ber, and further inducing the shift of the longitudinal modes of the fgesl, the lasing wavelength of the fgesl has a shift tendency to longer wavelengths with the increase of the temperature ; the mode hopping happens for a short external cavity and disappears for a long external cavity
數值模擬的結果表明:由於溫度變化造成半導體介質和光纖的折射率發生變化從而導致fgesl的縱模發生移動，因此fgesl的激射波長隨著溫度的升高將存在向長波長方向發生移動的趨勢，對于短外腔， fgesl的縱模間距較大，半導體介質折射率隨溫度的變化程度大於光纖折射率隨溫度的變化程度，因而存在模式跳躍現象;對于長外腔，由子fgesl的縱模間隔很小，因而不存在明顯的模式跳躍現象。
