style="text-indent:25px">未來，用作備份的可調(diào)激光器還要求有快的相應(yīng)速度。當(dāng)一個(gè)密集波分復(fù)用信道失效時(shí)，一個(gè)可調(diào)激光器可以自動(dòng)啟用使其恢復(fù)工作。要實(shí)現(xiàn)這個(gè)功能，激光器必須在10毫秒甚至更短的時(shí)間內(nèi)調(diào)到并鎖定在失效的波長(zhǎng)，這樣才能保證整個(gè)恢復(fù)時(shí)間短于同步光網(wǎng)絡(luò)要求的50毫秒以下。在動(dòng)態(tài)應(yīng)用中，要求可調(diào)諧激光器的波長(zhǎng)能在工作中有規(guī)律地變化，以增強(qiáng)光網(wǎng)絡(luò)的靈活性。這種應(yīng)用一般都要求能提供動(dòng)態(tài)的波長(zhǎng)，以便將一個(gè)波長(zhǎng)從一個(gè)網(wǎng)絡(luò)段中加入或提出，以適應(yīng)所要求的變化的容量。人們已經(jīng)提出了一種簡(jiǎn)單且更加靈活的ROADMs結(jié)構(gòu)：這是一個(gè)基于同時(shí)使用可調(diào)激光器和可調(diào)濾波器的架構(gòu)?？烧{(diào)激光器可以給系統(tǒng)加上某些波長(zhǎng)，而可調(diào)濾波器可以從系統(tǒng)中濾掉某些波長(zhǎng)?？烧{(diào)激光器還可以解決光交叉聯(lián)接里面的波長(zhǎng)阻斷問題。目前，大多數(shù)光交叉聯(lián)接在光纖兩端使用光-電-光交換界面來避免這種問題。如果在輸入端使用可調(diào)激光器向OXC輸入，可以選擇一定的波長(zhǎng)來保障光波以一個(gè)清晰的路徑到達(dá)終點(diǎn)。</p><p style="text-indent:25px">由于波長(zhǎng)可調(diào)諧激光器應(yīng)用非常普遍，因此出現(xiàn)的各種結(jié)構(gòu)的可調(diào)諧激光器可以應(yīng)用到不同的系統(tǒng)，各有優(yōu)缺點(diǎn)。外腔半導(dǎo)體激光器由于輸出功率**長(zhǎng)連續(xù)可調(diào)，因而可用于精密測(cè)試儀器中的寬帶可調(diào)光源。從光子集成以及滿足未來全光網(wǎng)的角度來看取樣光柵DBR，超結(jié)構(gòu)光柵DBR及與調(diào)制器、放大器等集成的可調(diào)諧激光器也許可成為有前途的可調(diào)諧光源。光纖光柵外腔可調(diào)諧激光器也是很有前途的一類光源，其結(jié)構(gòu)簡(jiǎn)單、線寬窄、易于光纖耦合，如果腔內(nèi)可集成EA調(diào)制器還可以作為高速可調(diào)諧光孤子源。另外，基于光纖激光器的可調(diào)諧光纖激光器近年來有相當(dāng)大的發(fā)展。可以預(yù)計(jì)，在光通信光源中可調(diào)諧激光器性能將會(huì)進(jìn)一步完善，市場(chǎng)占有份額將逐漸加大，具有非常光明的應(yīng)用前景。光纖光柵外腔可調(diào)諧激光器也是很有前途的一類光源，其結(jié)構(gòu)簡(jiǎn)單、線寬窄、易于光纖耦合。</p><div
