Guhitamo isoko nziza ya laser: inkomoko yohereza imyuka ya semiconductor laser Igice cya mbere

Guhitamo icyizaInkomoko: inkombe yohereza imyuka ya semiconductor laser
1. Intangiriro
Amashanyarazichip igabanyijemo ibice bisohora lazeri (EEL) hamwe nubuso bwa veritike yubusa isohora ibyuma bya lazeri (VCSEL) ukurikije uburyo butandukanye bwo gukora resonator, kandi itandukaniro ryihariye ryimiterere ryerekanwe mubishusho 1. Ugereranije nubuso bwa veritike ihagaritse gusohora laser, inkombe gusohora semiconductor laser tekinoroji yiterambere irakuze cyane, hamwe nuburebure bwagutse, hejuruamashanyaraziGuhindura imikorere, imbaraga nini nibindi byiza, bikwiranye cyane no gutunganya laser, itumanaho ryiza nibindi bice. Kugeza ubu, ibyuma bisohora ibyuma bisohora igice ni igice cyingenzi mu nganda za optoelectronics, kandi ibyo basabye byibanze ku nganda, itumanaho, siyanse, abaguzi, igisirikare n’ikirere. Hamwe niterambere niterambere ryikoranabuhanga, imbaraga, kwiringirwa hamwe ningufu zo guhindura ingufu za lazeri zoherejwe na semiconductor lazeri zaratejwe imbere cyane, kandi ibyifuzo byabo ni byinshi kandi binini.
Ibikurikira, nzakuyobora kugirango urusheho gushima igikundiro kidasanzwe cyo gusohora impandeicyuma gikoresha.

Igishushanyo 1 (ibumoso) cyohereza igice cya semiconductor laser na (iburyo) vertical cavity surface isohora laser structure igishushanyo

2. Ihame ryakazi ryumusemburo uhumanya ikirerelaser
Imiterere ya lazeri isohora igice cya kabiri kirashobora kugabanywamo ibice bitatu bikurikira: igice gikora igice cyakarere, isoko ya pompe na optique ya resonator. Bitandukanye na resonator ya vertical cavity surface-isohora lazeri (igizwe nindorerwamo zo hejuru na hepfo ya Bragg), resonator mubikoresho byohereza ibyuma bisohora ibyuma bya laser bigizwe ahanini na firime optique kumpande zombi. Ibikoresho bisanzwe bya EEL hamwe nuburyo bwa resonator byerekanwe mubishusho 2. Photon iri mumashanyarazi ya semiconductor ya laser yamashanyarazi yongerewe uburyo bwo guhitamo muri resonator, kandi lazeri ikorwa mubyerekezo bisa nubuso bwubutaka. Ibikoresho byohereza ibyuma bya semiconductor laser bifite intera nini yuburebure bwumurongo kandi birakwiriye mubikorwa byinshi bifatika, bityo bigahinduka imwe mumasoko meza ya laser.

Imikorere yo gusuzuma ibipimo byerekana ibyuma bisohora ibyuma bisohora ibyuma nabyo birahuza nibindi byuma byifashishwa, harimo: (1) laser lasing wavelength; . . (4) Gukora neza; (5) Gutandukana guhagaritse Inguni θ⊥; (6) Gutandukana gutambitse Inguni θ∥; .

Lazeri ya semiconductor ishingiye kuri GaAs ibikoresho bya semiconductor ni kimwe mu bikoresho bya tekinoroji ya semiconductor ikuze. Kugeza ubu, GAAS ishingiye hafi ya-infrarafarike (760-1060 nm) ibyuma bisohora ibyuma bisohora ibyuma byifashishwa mu bucuruzi. Nkibisekuru bya gatatu ibikoresho bya semiconductor nyuma ya Si na GaAs, GaN yahangayikishijwe cyane nubushakashatsi bwa siyansi ninganda kubera imiterere myiza yumubiri na chimique. Hamwe niterambere ryibikoresho bishingiye kuri optoelectronic GAN hamwe nimbaraga zabashakashatsi, diode itanga urumuri rwa GAN hamwe na lazeri zisohora inkombe.
