Guhitamo isoko nziza ya laser: laser ya semiconductor isohora imirasire igice cya mbere

Guhitamo ikintu cyizaisoko ya laser: laser ya semiconductor isohora imirasire y'izuba
1. Intangiriro
Leza ya semiconductorUduce duto dugabanyijemo uduce duto twa laser dutanga imirasire y'izuba (EEL) n'uduce duto twa laser dutanga imirasire y'izuba (VCSEL) hakurikijwe uburyo butandukanye bwo gukora resonators, kandi itandukaniro ryazo ryihariye rigaragazwa ku Ishusho ya 1. Ugereranyije na laser itanga imirasire y'izuba ihagaze, iterambere ry'ikoranabuhanga rya laser ya semiconductor itanga imirasire y'izuba rimaze igihe kinini, rifite uburebure bunini bw'uburebure, kandi rifite uburebure bwinshi.electro-opticalIngufu zo guhindura ibintu, ingufu nini n'izindi nyungu, zikwiriye cyane mu gutunganya laser, itumanaho ry'amatara n'izindi nzego. Kuri ubu, laser za semiconductor zisohora ibintu mu ntera ni igice cy'ingenzi cy'inganda za optoelectronics, kandi ikoreshwa ryazo ryagiye rikorerwa inganda, itumanaho, siyansi, abaguzi, igisirikare n'indege. Bitewe n'iterambere n'iterambere ry'ikoranabuhanga, imbaraga, ubwizerwe n'ubushobozi bwo guhindura ingufu za laser za semiconductor zisohora ibintu mu ntera byarushijeho kuba byiza, kandi amahirwe yo kuzikoresha ari menshi cyane.
Ibikurikira, ndaguyobora kurushaho kwishimira ubwiza budasanzwe bwo gutanga ibintu ku ruhandelaser za semiconductor.

Ishusho ya 1 (ibumoso) ya laser semiconductor isohora uruhande n'ishusho (iburyo) y'imiterere ya laser isohora ubuso buhagaze

2. Ihame ry'imikorere ya semiconductor yo mu ntera yo gusohora umwukalaser
Imiterere ya laser semiconductor isohora imipaka ishobora kugabanywamo ibice bitatu bikurikira: akarere gakora ka semiconductor, isoko ya pompe na resonator y'amajwi. Bitandukanye na resonator za laser zisohora imipaka hejuru n'inyuma (zigizwe n'indorerwamo za Bragg zo hejuru n'izo hasi), resonator mu bikoresho bya laser semiconductor isohora imipaka zigizwe ahanini na filime z'amajwi ku mpande zombi. Imiterere isanzwe y'igikoresho cya EEL n'imiterere ya resonator bigaragazwa ku Ishusho ya 2. Foton iri mu gikoresho cya laser semiconductor isohora imipaka yongerwamo uburyo bwo guhitamo muri resonator, kandi laser ikorwa mu cyerekezo gihuye n'ubuso bw'ubutaka. Ibikoresho bya laser semiconductor isohora imipaka bifite uburebure bwinshi bw'uburebure bw'umurambararo kandi bikwiranye n'ikoreshwa ry'ibintu byinshi, bityo biba bimwe mu bikomoka kuri laser byiza.

Ibipimo by'isuzuma ry'imikorere ya laser za semiconductor zisohora imirasire y'impande nabyo bihuye n'izindi laser za semiconductor, harimo: (1) ubunini bw'umurambararo wa laser; (2) Umuyoboro w'amashanyarazi Ith, ni ukuvuga umuyoboro wa laser diode itangira gukora oscillation ya laser; (3) Umuyoboro w'amashanyarazi Iop ikora, ni ukuvuga umuyoboro w'amashanyarazi iyo laser diode igeze ku ngufu z'umusaruro, iyi parametre ikoreshwa ku gishushanyo n'impinduka z'uruziga rwa laser; (4) Ingufu z'umurambararo; (5) Inguni yo gutandukana ihagaze θ⊥; (6) Inguni yo gutandukana itambitse θ∥; (7) Kugenzura Im y'umuyoboro, ni ukuvuga ingano y'umuyoboro wa laser ya semiconductor ku ngufu z'umusaruro zihagaze.

3. Iterambere ry'ubushakashatsi kuri GaAs na GaN based edge emit semiconductor lasers
Laser ya semiconductor ishingiye ku bikoresho bya semiconductor bya GaAs ni imwe mu ikoranabuhanga rya laser ya semiconductor ikuze cyane. Kuri ubu, laser za semiconductor zikoresha GAAS hafi ya infrared band (760-1060 nm) zikoresha impande zikoreshwa cyane mu bucuruzi. Nk'ibikoresho bya semiconductor byo mu gisekuru cya gatatu nyuma ya Si na GaAs, GaN yakomeje kwita cyane ku bushakashatsi bwa siyansi n'inganda kubera imiterere yayo myiza ya fiziki n'imiti. Hamwe n'iterambere ry'ibikoresho bya optoelectronic bishingiye kuri GAN n'imbaraga z'abashakashatsi, diode zikoresha urumuri zishingiye kuri GAN na laser zikoresha impande zikoreshwa byateye imbere mu nganda.
