Thaum lub laser diode txhaj thaum cov dej ntws hauv qab ntawm qhov tseem ceeb tam sim no ntom ntom, luminescence mechanism yog qhov txawv txav emission, qhov ntau qhov kev pom ntawm qhov dav, qhov dav dav ntawm txog 100 txog 500 angstroms (PSV=10-1 nano, yog ib qho ntawm ntau Atomic diameters ntawm kev txiav txim ntawm qhov ntau ntawm PSV. Tab sis thaum qhov ceev tam sim no dhau ntawm qhov tseem ceeb tus nqi, pib tsim oscillations, thaum kawg tsuas yog tso tes ntawm modal, thiab bandwidth txo mus rau 30 angstroms. Ntxiv mus, laser diode lub zog noj yog qhov tsawg heev, hauv ob-heterostructure laser. , piv txwv li, qhov ntsuas hluav taws xob ntau yog feem ntau tsawg dua 2 volts, qhov kev nkag ntawm tam sim no yog nruab nrab ntawm 15 txog 100 Ma, kev siv hluav taws xob tsawg dua ib zaug watt ntau tshaj kaum tawm ntawm Watts tso zis hluav taws xob.
Cov yam ntxwv ntawm laser diode, ib qho ntawm cov kev hloov tawm mus ncaj qha los ntawm lub zog tam sim no ntawm lub teeb. Vim tias lub zog tsim tawm thiab feem ntau txoj kev sib raug zoo ntawm cov tswv yim tam sim no, laser diodes tuaj yeem siv cov lus piv txwv lossis digital ncaj qha kev tsim tawm ntawm lub teeb pom kev siv tam sim no, tshem tawm cov khoom kim heev, yog li cov nqi pheej yig dua diode kev siv.
