Kugwira Mfundo Ya Semiconductor Laser

Mfundo Yogwira Ntchito yaSemiconductor laser

Choyamba, zofuna za magawo a semiconduct a Selector zimayambitsidwa, makamaka kuphatikizapo izi:
1.
2. Magawo opanga: monga kukula kochepa ndi makonzedwe, kutulutsa kumapeto kwake, kukula kwa mapangidwe ndi kukula kwa ulesi.
3.
4.
5. Mphamvu ndi magetsi: Mwa kuyeza mphamvu, magetsi ndi mapiko a semiconduct pa ntchito, PV, Pinves amatha kukopeka kuti amvetsetse zomwe akuchita.

Mfundo
1. Pezani zikhalidwe: Kugawa kosinthika kwa onyamula mu lasing sing'anga (yogwira dera) imakhazikitsidwa. Mu semiconductor, mphamvu yamagetsi imayimiriridwa ndi mndandanda wambiri wopitilira malire. Chifukwa chake, kuchuluka kwa ma elekitoni pansi pa gulu lowonjezera mu mphamvu yayikulu kuyenera kukhala lalikulu kwambiri kuposa kuchuluka kwa mabowo pamwamba pa zigawo ziwiri zamphamvu zapakati pa zigawo za kuchuluka kwa tinthu. Izi zimatheka pogwiritsa ntchito njira yabwino kwambiri yothandizira kapena kuyika jakisoni ndi jekesening zovomerezeka kuti zikondweretse ma elekitikidwe kuchokera ku gulu lamphamvu lamphamvu kwambiri kupita ku gulu lowonjezera lamphamvu. Pamene ambiri ma elekitoni mu tinthu tating'onoting'ono tinthu tomwe timabwezera mabowo, kutulutsa kolimbikitsa kumachitika.
2. Kwa fp yamkati (kuphatikiza-setch-seti) semiconductor laser, fp carch ikhoza kupangidwa mosavuta pogwiritsa ntchito chilengedwe cha cleavager perpecticy ku ndege ya kN.
. Izi zikuyenera kukhala ndi jakisoni wamphamvu yapano, ndiye kuti, pali gawo lokwanira la kuchuluka kwa tinthu, chiwerengero chachikulu cha tinthu, chiwerengero chachikulu chomwe chingachitike, ndicho, chofunikirachi chiziyenera kukwaniritsa chiwongola dzanja. Nyengo ikafika pakhomo, kuwala ndi mawonekedwe enaake kumatha kuchepetsedwa m'matumba ndikukulitsidwa, kenako ndikupanga laser ndikutulutsa.

Zofunikira
1. Kusintha kwa Bandwidth ndi Mtengo wa Semiconduct Lasers ndipo ukadaulo wawo wosinthira zilibe kanthu, ndipo kusinthitsa ma bwindth ndi kuwuka kumakhudza mwachindunji. Mafuta osankhidwa mkati (mwachindunji laser) Ndioyenera magawo osiyanasiyana mu kulumikizana kwamitengo yamitseko chifukwa cha kuchuluka kwake kwapamwamba komanso mtengo wotsika.
2. Makhalidwe a Squrarral ndi Zosintha Kusintha: Semiconductor adagawana ma LasersDfb laser) Popeza ndi gwero lofunikira mu kulumikizana kwa masamba ndi kulumikizana kwamaso chifukwa cha mawonekedwe ndi mitundu yawo yabwino.
3. Mtengo wowerengeka: Semicoctor a Semicouctor assers ayenera kukhala ndi maubwino a mtengo wotsika ndi zakudya kuti akwaniritse zosowa zazikulu zopanga ndi mapulogalamu.
4. Kugwiritsa ntchito mphamvu ndi kudalirika: mu malo ogwiritsira ntchito monga malo opangira deta, a Semicoctor a Semicoctor amafunikira kugwiritsa ntchito mphamvu zochepa komanso kudalirika kwakukulu kuti akwaniritse ntchito yokhazikika.
