【正文】 距離、大容量的光信息傳輸系統(tǒng)無(wú)不都采用分布反饋式半導(dǎo)體激光器(DFBLD)。半導(dǎo)體激光器的問(wèn)世極大地推動(dòng)了信息光電子技術(shù)的發(fā)展，到如今，它是當(dāng)前光通信領(lǐng)域中發(fā)展最快、對(duì)光纖通信產(chǎn)生了重大影響，并加速了它的發(fā)展。1978年，半導(dǎo)體激光器開始應(yīng)用于光纖通信系統(tǒng)，半導(dǎo)體激光器可以作為光纖通信的光源和指示器以及通過(guò)大規(guī)模集成電路平面工藝組成光電子系統(tǒng)。半導(dǎo)體激光器是成熟較早、進(jìn)展較快的一類激光器，由于它的波長(zhǎng)范圍寬，制作簡(jiǎn)單、成本低、易于大量生產(chǎn)，并且由于體積小、重量輕、壽命長(zhǎng)，因此，品種發(fā)展快，應(yīng)用范圍廣，目前已超過(guò)300種，半導(dǎo)體激光器的最主要應(yīng)用領(lǐng)域是Gb局域網(wǎng)，850nm波長(zhǎng)的半導(dǎo)體激光器適用于1Gb局域網(wǎng)系統(tǒng)；1300nm 1550nm波長(zhǎng)的半導(dǎo)體激光器適用于10Gb局域網(wǎng)系統(tǒng)。of PID. In the whole regulator, the control action of proportion, integral and derivative is associated. Parameters can be adjusted separately, you can use one to twot require an externala light arises. This paper describes the basic structure of semiconductor laser. Lasers are usually posed of three parts: laser work material, the pump source and optical resonant cavity. Although semiconductor laser is a kind solid laser, it uses the way of injection cavity while然后分析了半導(dǎo)體熱電致冷器(TEC)的基本工作原理，它是以帕爾帖效應(yīng)為基礎(chǔ)，當(dāng)電流流過(guò)TEC時(shí)，熱量由TEC的一側(cè)傳送到另一側(cè)，表現(xiàn)為其一端致冷，另一端加熱；接著介紹了PWM驅(qū)動(dòng)原理和PID溫度補(bǔ)償控制的原理，在整個(gè)調(diào)節(jié)器中，比例、積分和微分的控制作用是關(guān)聯(lián)的關(guān)系，參數(shù)可以分別調(diào)節(jié)，也可以只采用其中的一到兩種控制規(guī)律，最后通過(guò)對(duì)幾種驅(qū)動(dòng)原理和PID溫度補(bǔ)償控制原理的學(xué)習(xí)，進(jìn)而對(duì)線性功率管溫控電路、MAXl978構(gòu)成的溫控電路及ADN8830構(gòu)成的溫控電路進(jìn)行了分析。本文首先闡述了半導(dǎo)體激光器的基本結(jié)構(gòu)，通常激光器都是由三部分組成：激光工作物質(zhì)、泵浦源和光學(xué)諧振腔。優(yōu)秀畢業(yè)設(shè)計(jì)半導(dǎo)體激光器的溫控電路分析摘要 半導(dǎo)體激光器是以一定的半導(dǎo)體材料做工作物質(zhì)而產(chǎn)生受激發(fā)射作用的器件。其工作原理是通過(guò)一定的激勵(lì)方式，在半導(dǎo)體物質(zhì)的能帶(導(dǎo)帶與價(jià)帶)之間，或者半導(dǎo)體物質(zhì)的能帶與雜質(zhì)(受主或施主)能級(jí)之間，實(shí)現(xiàn)非平衡載流子的粒子數(shù)反轉(zhuǎn)，當(dāng)處于粒子數(shù)反轉(zhuǎn)狀態(tài)的大量電子與空穴復(fù)合時(shí)，便產(chǎn)生受激發(fā)射作用。半導(dǎo)體激光器雖說(shuō)屬于一種固體激光器，但它是使用注入電流的方法，依靠電流流經(jīng)介質(zhì)產(chǎn)生電子和空穴的復(fù)合過(guò)程形成光輻射，因此，不需要外部的泵浦源。關(guān)鍵詞 溫度控制 熱電致冷器 線性功率管 PID溫度補(bǔ)償控制Temperature control circuit of semiconductor lasersYu DengrongAbstract ：Semiconductor laser are parts of an apparatus which based on certain semiconductor materials as work substance, and it is produced by the stimulated emission, its working principle is by way of certain incentives, between the band of semiconductor material (conduction band and valence band ), or between the band of semiconductor material and impurity band (acceptor or donor), to achieve nonequilibrium carrier population inversion, when the electron which is in the state of inversion of particles and electron mix, the role of stimulated emissioncurrent flows through the mediators and formradiation Therefore, doesn39。pump source, then this paper analyzes the basic working principle of the semiconductor, thermoelectric cooler (TEC). It is based on Peltier effect when the current flows through the TEC, the heat transfers from one side of TEC to the other. One end of the performance of their refrigeration, heating the other end, then, it continues to introduce the PWM driving principle and the principle of temperature pensation controlkinds of control laws of them. Finally, by the study of several deriving principles and the principle of temperature pensation control of PID, then continuing to analyze the temperature control circuit for liner power control, the temperature control circuit formed by MAX1987 and the temperature control circuit posed by ADN8830.Key words：Temperature control Thermoelectric Cooler Linear power transistor Temperature pensation control of PID目 錄中文摘要……………………………………………………………………………………（Ⅰ）英文摘要……………………………………………………………………………………（Ⅱ）第一章 緒論………………………………………………………………………………（1）第二章 半導(dǎo)體激光器的結(jié)構(gòu)……………………………………………………………（3） ………………………………………………………………（3） ……………………………………………………………………（5） …………………………………………………………………………（6）第三章 幾種常用驅(qū)動(dòng)工作原理及PID溫度補(bǔ)償控制原理……………………………（7）
