摘要:	本論文從理論出發，透過光纖模態可以計算得到色散和非線性係數。再藉由非線性薛丁格方程式的模擬結果制定錐形光纖的規格，發現光纖直徑在到具有最寬的光譜。接著根據數值模擬所設計的參數來製作錐形光纖，且對錐形光纖與正常光纖作光學量測，可得知錐形光纖的光譜較正常光纖寬。說明對於光譜展寬，製作錐形光纖的有效性與必要性。最後並進一步嘗試應用在同調反史托克拉曼散射顯微術的架設。; Theoretically, dispersion and nonlinear coefficient can be calculated through fiber modes. To achieve appropriate spectral broadening, we determine the specifications of tapered fiber based on the numerical simulations of the NLS equation. The widest spectral width occurs when the diameter of the fiber lying between and . We fabricate the tapered fiber following the results of numerical simulations and compare the output spectrum of tapered fiber and that of a normal fiber. The width of output spectrum of tapered fiber is wider than normal fiber. This indicates that the tapered fiber is useful and essential for spectral broadening. Furthermore, we also apply the tapered fiber to the coherent anti-Stokes Raman scattering setup.
