Incamake ya modulatori enye zisanzwe

Uru rupapuro rutangiza uburyo bune bwa module (guhindura laser amplitude muri nanosecond igihe ntarengwa cya domein) ikoreshwa cyane muri sisitemu ya fibre laser. Muri byo harimo AOM (uburyo bwa acousto-optique), eom (eop-optic modulation), som /Soa(Semiconductor yoroshye yoroshye kandi azwi nka semiconductor modulation), kandiGuhindura Ladse. Muri bo, AOM,Eom, Som ni iy'amoko yo hanze, cyangwa guhindura itaziguye.

1.. Modulator ya Acousto-Optique (AOM)

Guhinduranya Acousto-optique ni inzira yumubiri ikoresha acousto-optique kugirango yishyure amakuru kumurongo wa optique. Iyo modulating, ibimenyetso by'amashanyarazi (amplitution modulation) byakoreshejwe bwa mbere kuri electro-acoustic transducer, bihindura ibimenyetso by'amashanyarazi mu murima ultrasonic. Iyo umuraba wicyo unyuze muri acousto-optique, umwikorezi wa optique arahinduka kandi agahinduka ubukana bwamoko atwara amakuru kubera ibikorwa bya acousto-optic

2. Modutor ya electro-optique(EOM)

Modutor ya electro-optique ni modulator ikoresha ingaruka za electro-optique ziterwa na kaburimbo zimwe na zimwe za etage ya electique, nka lithium ariobate (Linb03), Gaas) na lita03). Ingaruka ya electro-optique ni uko voltage ikoreshwa kuri electro-optique ya electal ya electro-optique izahinduka ibiranga urumuri, kandi bituma icyiciro cya kirimbuzi kizahinduka mubiranga urumuri rwicyo.

Igishushanyo: Iboneza ryumuzunguruko wa EOH

3. Semiconductor Modulator Modulator / Semiconductor Oplifier Amplifier (Som / Soa)

Semiconductor Oplifier Amplifier (SOA) isanzwe ikoreshwa kubimenyetso bya optufication, bifite akamaro ka chip, ingufu zamashanyarazi, etc., Kandi ni ejo hazaza kuri Amplifiers gakondo nka EDFA (Erbium-Iperereza rya fibre). Semiconductor modulator ya optique (som) nigikoresho kimwe nka semiconductor amplifier ya oplifier, ariko ibipimo bikoreshwa mugihe bikoreshwa mugihe gikoreshwa nka modulator gakondo itandukanijwe gato nibikoreshwa nka amplifier. Iyo ukoreshwa kubimenyetso bya optufication, ubusanzwe gutwara ibinyabiziga bihamye bihabwa Saa kugirango tumenye neza ko soa ikora mukarere ka Liyar; Iyo ikoreshwa muguhindura optique optique, biragukomeza ibimenyetso bya optique kuri soa, bikoresha amashanyarazi kugirango ugenzure moteri ya soa kurubu, hanyuma ugenzure ibisohoka kuri soa uko byanze bikunze / kwiyongera. Gukoresha ibirango bya SPLIC hamwe nibiranga ubushake, ubwo buryo bwa modulation bwakoreshwa buhoro buhoro kubisabwa, nka fibre ya optique twumva, lidar, ibitekerezo byubuvuzi byakwakira nibindi bice. Cyane cyane kubitekerezo bimwe bisaba amajwi menshi, gukoresha imbaraga no kugabanyirizwa.

4. Laser modulation irashobora kandi guhindura ibimenyetso bya optique no kugenzura itaziba rya laser Birashobora kugaragara ko hari spike mu ntangiriro ya pulse, izanwa no kwidagadura kwa uwitwara neza. Niba ushaka kubona pulse ya Pitoseconds 100 picoseconds, urashobora gukoresha iyi spike. Ariko mubisanzwe ntidushaka kugira ibi.

Inzego

AOM irakwiriye kuvunika amashanyarazi ya Optique muri Watts nke kandi ifite imikorere yo guhinduranya. Eom yihuta, ariko disiki yoroshye ni ndende kandi igipimo kizimangana. Som (soa) nigisubizo cyiza cya GHZ cyihuta cya Ghz hamwe nigipimo cyimikorere kinini, hamwe namashanyarazi make, miniturution nibindi biranga. Diosed ya lases itaziguye nicyo gisubizo cyiza, ariko umenye impinduka mubitekerezo byiza. Buri gahunda yo guhinduranya ifite ibyiza byayo nibibi, kandi ni ngombwa kumva neza ibyangombwa bisabwe mugihe uhitamo ibyiza nibibi bya buri gishushanyo, hanyuma uhitemo gahunda ikwiye. Kurugero, mugukwirakwiza fibre yuzuye, aom nibyingenzi, ariko mubishushanyo bishya bya sisitemu, imigambi mishya ya SHAKA ikoresha vuba, muri gahunda nshya yumuyaga, igabanya ubunini bwa Aom, no kunoza ubunini bwa Aom Muri sisitemu yitumanaho, sisitemu yihuta isanzwe yemeza gahunda itaziguye, kandi sisitemu yihuta isanzwe ikoresha gahunda ya elegitori-optique.
