Ubwoko bwa modulator ya laser

Ubwa mbere, modulation yimbere hamwe no guhinduranya hanze
Ukurikije isano ugereranije hagati ya Modulator na laser, theGuhindura Ladulationirashobora kugabanywamo modulation yimbere no guhinduranya hanze.

01 Guhindura imbere
Ikimenyetso cya modulation kikorwa mugikorwa cya laser osserlation, ni ukuvuga ibipimo bya laser oscacition yahinduwe nkuko amategeko yicyicaro cyahinduwe, kugirango ahindure ibiranga ibisohoka bya laser no kugera ku moko.

02 Guhindura hanze
Guhindura byo hanze ni ugutandukana kw'ibisekuru bya laser no guhinduranya. Bivuga gupakira ibimenyetso bya modulation nyuma yo gushiraho laser, ni ukuvuga, modulator ishyizwe muburyo bwa optique hanze ya resenator ya laser.
Imyitwarire ya modulation yongewe kuri modulator kugirango igaragaze ibiranga umubiri icyiciro cya modulator, kandi iyo laser inyuzemo, bimwe mu bipimo byumucyo bihindura, bityo bitwara amakuru bigomba kwanduzwa. Kubwibyo, modulation yo hanze ntabwo igomba guhindura ibipimo bya laser, ahubwo ni guhindura ibipimo byibisohoka laser, nkimbaraga, inshuro, inshuro, nibindi.

Icya kabiri,Modulator ya Lasergutondekanya
Nk'uko byakoranye gahunda ya modulator, birashobora gushyirwa mu byiciroGuhindura electro-optique, modulation ya acoustoptic, magneto-optique modulation no guhindura itaziguye.

01 Guhindura neza
Gutwara imodoka yaSemiconductor LaserCyangwa diode yoroshye yoroheje iragushukwa hejuru yikimenyetso cyamashanyarazi, kugirango urumuri rusohoka ruhindurwe nimpinduka yikimenyetso cyamashanyarazi.

(1) Guhindura TTL muburyo butaziguye
Ikimenyetso cya TTL cyongeweho kumashanyarazi ya laser, kugirango umusekeri wa laser ushobore kugenzurwa ibimenyetso byo hanze, hanyuma ibisohoka laser inshuro nyinshi birashobora kugenzurwa.

(2) Guhindura Anamalog muburyo butaziguye
Usibye gutanga amashanyarazi ya laser ibimenyetso (amplitude bitarenze 51 bihindura ibimenyetso byo hanze), birashobora gukora ibimenyetso byo hanze byinjizamo voltage itandukanye ijyanye na lases ihuye na laser

02 electro-optique ya modulation
Modulation ukoresheje ingaruka za electro-optro-optique zitwa elegito-optique. Urufatiro rwumubiri rwa elegique ningaruka za electro-optique, ni ukuvuga mubikorwa byumurima wamashanyarazi uzahinduka, kandi iyo imyanya ya kirisiti izahinduka, kandi iyo imyanya yumucyo izahinduka, kandi iyo imyanya yumucyo izahinduka, kandi iyo imurikagurisha ryanyuze muri ubu buryo, ihindura izagira ingaruka kandi ihinduka.

03 acousto-optique modulation
Urufatiro rwa Acousto-optique ni ingaruka za acousto-optique, bivuga ibintu byerekana ko imiraba yoroheje iratandukanye cyangwa ikwirakwizwa numurima udasanzwe mugihe ubanza gukwirakwiza hagati. Iyo indangagaciro ikwiye ihinduka riciriritse buri gihe kugirango ifate indangagaciro igaragarira mugihe gikwirakwiza iyo umuvurungano woroheje mubiciriritse, kandi ubukana, inshuro nicyerekezo cyumucyo utandukanye kizahinduka hamwe nimpinduka zumurima wa supergenerated.
Guhinduranya Acousto-optique ni inzira yumubiri ikoresha ikintu cya acousto-optique kugirango yishyure amakuru ku mutwara neza. Ikimenyetso cyahinduwe cyashyizwe kuri electro-acoustic transducer muburyo bwikimenyetso cyamashanyarazi (amplitution modulation), hamwe nisonga amashanyarazi yahinduwe muburasirazuba bwa ultrasosonic. Iyo umucyo wicyo unyuze mubiciriritse-optique, umwikorezi wa optique ahinduka kandi agahinduka ubukana bwagutse wave "itwara" amakuru.

04 magneto-optique moduction
Magneto-optic modulation ni ugusaba electronagneti ya faraday neza. Iyo urumuri rwinshi rwamamaza runyuze muri magneto-optique hagati yicyerekezo cyumurima wa rukuruzi, phenomenon yo kuzenguruka indege ya polarique yumucyo wijimye witwa magneti yitwa magneti izunguruka.
Umurima uhoraho wa magnetic ukoreshwa mubufasha kugirango ugere ku bwuzu bwa magneti. Icyerekezo cyumurongo wa rukuruzi wumuzunguruko uri mu cyerekezo cyacyo cya giciriritse, kandi kuzunguruka kwa faraday biterwa n'umurima wa magneti. Kubwibyo, nukugenzura ikiriri cya metero ndende-inshuro nyinshi kandi uhindura imbaraga za magnetiki yerekana ibimenyetso bya axial, inguni yindege ya optimation yindege ya oplikique irashobora kugenzurwa, kugirango urumuri ruhindurwe nimpinduka za θ inguni.
