Qhia txog kev ntim khoom ntawm cov khoom siv optoelectronic

Optoelectronic ntaus ntawv system ntimOptoelectronic ntaus ntawvntim system yog txheej txheem kev sib koom ua ke los ntim cov khoom siv optoelectronic, cov khoom siv hluav taws xob thiab cov khoom siv ua haujlwm. Optoelectronic ntaus ntawv ntim yog dav siv nyob rau hauvoptical kev sib txuas lussystem, cov ntaub ntawv chaw, muaj laser, civil optical zaub thiab lwm yam teb. Nws tuaj yeem muab faib ua cov ntim ntim hauv qab no: nti IC qib ntim, ntim khoom, ntim khoom ntim, txheej txheej pawg ntim ntim, subsystem sib dhos thiab kev sib koom ua ke.

Optoelectronic li txawv ntawm cov khoom siv semiconductor, ntxiv rau cov khoom siv hluav taws xob, muaj cov txheej txheem kho qhov muag, yog li cov qauv pob ntawm cov cuab yeej yog qhov nyuaj dua, thiab feem ntau yog tsim los ntawm qee cov khoom sib txawv. Cov sub-components feem ntau muaj ob lub qauv, ib qho yog laser diode,photodetectorthiab lwm qhov chaw raug ntsia rau hauv lub pob kaw. Raws li nws daim ntawv thov tuaj yeem muab faib ua cov qauv kev lag luam thiab cov neeg siv khoom xav tau ntawm pob khoom. Cov txheej txheem lag luam tuaj yeem muab faib ua coaxial TO pob thiab pob npauj npaim.

1.TO pob Coaxial pob yog hais txog cov khoom siv kho qhov muag (laser nti, lub teeb pom kev rov qab) hauv lub raj, lub lens thiab txoj kev kho qhov muag ntawm cov fiber ntau txuas sab nraud yog nyob rau tib lub axis. Lub laser nti thiab backlight detector nyob rau hauv lub coaxial pob ntaus ntawv yog mounted rau lub thermal nitride thiab txuas nrog rau sab nraud Circuit Court los ntawm cov hlau lead kub. Vim tias tsuas muaj ib lub lens hauv pob coaxial, qhov kev sib txuas ua haujlwm tau zoo dua piv nrog cov pob npauj npaim. Cov khoom siv rau TO tube plhaub feem ntau yog stainless hlau lossis Corvar alloy. Tag nrho cov qauv yog tsim los ntawm lub hauv paus, lub lens, sab nraud txias thaiv thiab lwm yam, thiab cov qauv yog coaxial. Feem ntau, TO pob lub laser hauv lub laser nti (LD), backlight detector nti (PD), L-bracket, thiab lwm yam. Yog hais tias muaj ib qho kev tswj qhov kub thiab txias xws li TEC, sab hauv thermistor thiab tswj nti kuj xav tau.

2. Npauj npaim pob Vim tias cov duab zoo li npauj npaim, daim ntawv pob no hu ua npauj npaim pob, raws li pom hauv daim duab 1, cov duab ntawm npauj npaim sealing optical ntaus ntawv. Piv txwv li,npauj npaim SOA(npauj npaim semiconductor optical amplifier). Nws muaj qee tus yam ntxwv, xws li qhov chaw loj hauv pob npauj npaim, yooj yim rau mount lub semiconductor thermoelectric txias, thiab paub txog qhov sib xws ntawm kev tswj qhov kub thiab txias; Qhov cuam tshuam laser nti, lens thiab lwm yam khoom yog yooj yim rau kev teeb tsa hauv lub cev; Cov yeeb nkab ob txhais ceg raug faib rau ob sab, yooj yim kom paub txog kev sib txuas ntawm lub voj voog; Cov qauv yog yooj yim rau kev sim thiab ntim. Lub plhaub feem ntau yog cuboid, cov qauv thiab kev ua haujlwm feem ntau yog qhov nyuaj, tuaj yeem ua rau hauv tub yees, lub dab dej kub, ceramic puag thaiv, nti, thermistor, saib xyuas lub teeb, thiab tuaj yeem pab txhawb kev sib koom ua ke ntawm tag nrho cov khoom saum toj no. Lub plhaub loj cheeb tsam, zoo cua sov dissipation.
