The first order weakly - guiding approximation for the eigenvalue equation of hybrid modes in a step - index optical fiber 階躍光纖中混合模式特征方程的一階弱導(dǎo)近似
This paper enclose the mode and the density distribution property of the step - index optical fiber after plane wave coupled into it 本文研究均勻平面波本經(jīng)階躍光纖的傳播特性和輸出光強(qiáng)分布特性。
The second part is the mode transition property and the energy occupation of each mode in step - index optical fiber according to the mode solution 結(jié)果表明, te _ ( 11 )模是階躍光纖中傳播的基模,并占有總能量的大部分。
Third , the mode solution is obtained using the separation of variables . the last , the mode transition property is discussed when the plane wave transmit in the step - index optical fiber 再次,利用分離變量法推導(dǎo)出平面波在階躍光纖中傳播的模式表達(dá)式,討論了光波在光纖中傳播的模式特性。
