Umgomo Wokusebenza Kwe-Semidenductor Laser

Ukusebenza komgomo weI-Semiconductor Laser

Okokuqala, izidingo zamapharamitha zama-semiconductor lasers zethulwa, ikakhulukazi kufaka phakathi izici ezilandelayo:
1. Ukusebenza kwe-PhotoElectric: kufaka phakathi isilinganiso sokuqothulwa, i-Dynamic LineWidth namanye amapharamitha, la mapharamitha athinta ngokuqondile ukusebenza kwama-Semiconductor Lasers ezinhlelweni zokuxhumana.

I-5. Amandla kanye namavola: Ngokulinganisa amandla, ama-voltage kanye namanje we-semiconductor laser emsebenzini, i-PV, ama-PI kanye nama-iv curves angadonswa ukuze aqonde izici zawo zokusebenza.

Umgomo Wokusebenza
1. Thola imibandela: Ukusatshalaliswa kwe-Inversion Carriers ku-Lasing Medium (Isifunda Esisebenzayo) kusunguliwe. Ku-semiconductor, amandla ama-elektroni amelelwa uchungechunge lwamazinga acishe abe aqhubekayo. Ngakho-ke, inani lama-elektroni ezansi kwebhande le-conduction e-High Energy State kumele libe likhulu kunenombolo yezimbobo phezulu kwebhendi eliphansi elisezingeni eliphakeme le-Energy Band Provion phakathi kwenombolo yezinhlayiyana. Lokhu kutholakala ngokusebenzisa ukukhetha okuhle ekusebenziseni noma ekusebenzeni kwe-heterojujunbs futhi kufakwe izithwali ezidingekayo kungqimba esebenzayo ukuze kujabulise ama-elektroni aqhamuka ebhendi eliphansi lamandla ebhendi ephakeme. Lapho inani elikhulu lama-elektroni esihlaseli esibuyiselwe esihlahleni sabantu ababuyisiwe babuya kabusha ngezimbobo, ukuphuma okuvuselelayo kwenzeka.
2. Ukuze empeleni uthole imisebe ehambisanayo evuselelayo, imisebe evuselelwayo kufanele yondliwe ibuye kaninginingi ku-resonator ye-Laser ye-Cleavage ye-Cleavage ye-Cleavage ye-Cleavage ye-Miconductor Drilayer Disclector Discilayer file, futhi i-smooth suppect ispection ekhanyayo Ifilimu. Nge-FP Cavity (Fabry-Perot Cavity) i-Semiconductor Laser, i-FP Cavity ingakhiwa kalula ngokusebenzisa indiza yemvelo ye-Cleavage Perpendicular iplanethi ye-PN Junction yekristali.
. Lokhu kumele kube nomjovo onamandla wamanje, okungukuthi, kunezinhlayiya zenombolo eyanele, kukhuphuka izinga lokuphambuka kwenombolo, okukukhulu kakhulu, okungukuthi, okudingekayo kufanele kuhlangane nesimo esithile sevembo. Lapho i-laser ifinyelela umkhawulo, ukukhanya okune-wavelength ethile kungahle kube khona emgodini futhi kwandiswa, ekugcineni kwakha i-laser nokuphuma okuqhubekayo.

Isidingo sokusebenza
1 I-laser ye-laser yangaphakathi (i-laser elungisiwe ngokuqondile) Ilungele izinkambu ezahlukahlukene ekuxhumaneni kwe-fiber optical ngenxa yokudluliselwa kwayo okuphezulu kanye nezindleko eziphansi.
2. Izici ezibukekayo kanye nezimpawu zokushintshanisa:I-DFB laser) Ube ngumthombo obalulekile wokukhanya ekuxhumaneni kwe-fiber okubonakalayo nokukhulumisana kwesikhala ngenxa yezimpawu zazo ezinhle kakhulu zokubukeka nezimpawu zokushintshana.
I-3. Izindleko kanye nokukhiqizwa kwesisindo
4. Ukusetshenziswa kwamandla kanye nokwethenjwa
