Mugihe ingufu za lazeri zikoreshwa cyane zikomeje kwaguka, utubari twa laser diode twabaye ingenzi mubice nko kuvoma laser, gutunganya inganda, ibikoresho byubuvuzi, nubushakashatsi bwa siyansi. Nimbaraga zabo nziza cyane, ubunini bwa modular, hamwe nubushobozi buke bwa electro-optique, ibyo bikoresho nibyingenzi bya sisitemu nyinshi zigezweho. Nyamara mubintu byinshi byerekana imikorere ya laser diode bar, ikintu kimwe gikunze kwirengagizwa ariko ni ngombwa cyane: impande zinyuranye. Iyi ngingo iragaragaza ibiranga, inkomoko yumubiri, ningaruka zimpande zinyuranye mu tubari twa laser diode - nuburyo igishushanyo mbonera gishobora kugicunga neza.
1. Inguni yo Gutandukana Niki?
Inguni yo gutandukana isobanura uburyo urumuri rwa lazeri rukwirakwira mu mwanya wubusa. Irerekana urugero urumuri rwaguka ruva mu kirere. Mu tubari twa laser diode, impande zinyuranye zerekana asimmetrie ikomeye mubyerekezo bibiri byingenzi:
Axis yihuta: Perpendicular kumurongo wumurongo. Agace kangiza imyuka ni nto cyane (mubisanzwe 1-2 µm), biganisha ku mpande nini zitandukanye, akenshi 30 ° –45 ° cyangwa zirenga.
Buhoro buhoro: Buringaniye n'uburebure bwumurongo. Agace kangiza imyuka ni nini cyane (microni amagana), bigatuma impande zinyuranye zitandukana, mubisanzwe hafi 5 ° –15 °.
Uku gutandukana kwa asimmetricike nikibazo gikomeye cyo gushushanya sisitemu yo guhuza ibice bya laser diode.
2. Inkomoko yumubiri yo gutandukana
Inguni yo gutandukana igenwa cyane cyane nimiterere ya waveguide nubunini bwibisohoka:
Muburyo bwihuse, imyuka ihumanya ni nto cyane. Ukurikije ibitekerezo bitandukanya, aperture ntoya itera gutandukana kwinshi.
Muri buhoro buhoro, urumuri rwaguka muburebure bwumurongo hejuru y’ibisohoka byinshi, bikavamo inguni ntoya.
Nkigisubizo, utubari twa laser diode dusanzwe twerekana gutandukana kwinshi murwego rwihuta no gutandukana kworoheje.
3. Uburyo Inguni Itandukana igira ingaruka kuri sisitemu
Cost Igiciro kinini cyo gukusanya hamwe no gushiraho ibiti
Bitewe na asimmetrie yo hejuru yibiti bibisi, hagomba gukoreshwa optique ya FAC (Yihuta ya Axis Yihuta) na SAC (Slow Axis Collimation). Ibi byongera sisitemu igoye kandi isaba kwishyiriraho hejuru neza hamwe nubushyuhe bwumuriro.
Gukora neza kwa Fibre
Iyo uhuza laser bar muri fibre nyinshi, sisitemu ya optique, cyangwa lensike ya aspheric, itandukaniro rinini ryihuta ryihuta rishobora kuganisha kumurongo "kumeneka," bikagabanya gukora neza. Gutandukana nisoko nyamukuru yo gutakaza optique.
Quality Ubwiza bwibiti muburyo bwo gutondeka
Mubice byinshi byegeranye modules, kugenzurwa nabi gutandukana birashobora gutera urumuri rutaringaniye cyangwa kugoreka kure-kure, bigira ingaruka kumyumvire no gukwirakwiza ubushyuhe.
4. Uburyo bwo Kugenzura no Guhindura Gutandukana muri Bare ya Laser Diode
Nubwo gutandukana ahanini bisobanurwa nuburyo bwibikoresho, ingamba nyinshi zo murwego rwa sisitemu zirashobora gukoreshwa muburyo bwiza:
①Gukoresha Lens
Gushyira lens-yihuta yo gukusanya hafi yuruhande rusohoka bigabanya urumuri kandi bikagabanya gutandukana mumurongo wihuse - ibi nibyingenzi mubishushanyo byinshi.
②SAC Lens yo Kwiyongera
Nubwo buhoro-buhoro gutandukana ni bito, gushiraho biracyakenewe mumirongo cyangwa umurongo-wumucyo kugirango ugere kumusaruro umwe.
③Igishushanyo mbonera hamwe nuburyo bwiza bwo gushushanya
Gukoresha micro-lens array, lens ya silindrike, cyangwa optique yubatswe irashobora gufasha gushiraho imirongo myinshi ya laser mumucyo mwinshi-mwinshi, ibisohoka bimwe.
④Igikoresho-Urwego Waveguide Optimisation
Guhindura igicucu cyibikorwa byububiko, igishushanyo mbonera, hamwe nuburyo bwo gusya birashobora kurushaho kunonosora itandukaniro ryihuse kuva kurwego rwa chip.
5. Kugenzura Gutandukana Mubyukuri-Isi Porogaramu
①Inkomoko ya pompe
Muri sisitemu ikomeye-ikomeye cyangwa fibre laser sisitemu, utubari twa laser diode ikora nkisoko ya pompe. Kugenzura itandukaniro-cyane cyane mu muvuduko wihuse - bitezimbere guhuza hamwe no kwibanda kumurongo.
②Ibikoresho byo kwa muganga
Kuri sisitemu nka lazeri yo kuvura no kuvanaho umusatsi, gucunga itandukaniro bitanga uburyo bumwe bwo gutanga ingufu hamwe no kuvura neza, kuvura neza.
③Gutunganya ibikoresho byinganda
Mu gusudira laser no gukata, uburyo bwiza bwo gutandukana bugira uruhare runini rwimbaraga, kwibanda neza, hamwe no gutunganya neza.
6. Umwanzuro
Inguni yo gutandukana ya laser diode bar ni ingingo yingenzi yinzibacyuho - kuva mikoro ntoya ya chip physique kugeza kuri macro-nini ya optique sisitemu.
Ikora nkibipimo byerekana ubuziranenge hamwe nimbibi yo gushushanya. Nkuko porogaramu isaba hamwe na sisitemu igoye ikomeza kwiyongera, gusobanukirwa no kugenzura itandukaniro biba ubushobozi bwibanze kubakora laser hamwe nababishyira hamwe - cyane cyane mugutezimbere imbaraga zisumba izindi, umucyo, no kwizerwa.
