Ihame ryakazi rya laser ya semiconductor

Ihame ry'akazi ryasemiconductor laser

Mbere ya byose, ibipimo bisabwa kuri semiconductor lasers byatangijwe, cyane cyane harimo ibi bikurikira:
.
2. Ibipimo byubaka: nkubunini bwa luminous na gahunda, ibisobanuro byanyuma byo gukuramo, ingano yububiko nubunini bwerekana.
3. Uburebure bwumurongo: Uburebure bwumurambararo wa semiconductor laser ni 650 ~ 1650nm, kandi ukuri ni hejuru.
4. Umuyoboro wa Threshold (Ith) hamwe nubushakashatsi bugezweho (lop): Ibipimo byerekana imiterere yo gutangira nuburyo bukora bwa laser ya semiconductor.
5. Imbaraga na voltage: Mugupima imbaraga, voltage numuyoboro wa semiconductor laser kumurimo, PV, PI na IV umurongo urashobora gukururwa kugirango wumve ibiranga akazi.

Ihame ry'akazi
1. Muri semiconductor, ingufu za electron zigaragazwa nuruhererekane rwingufu zikomeza. Kubwibyo, umubare wa electroni hepfo yumurongo wogutwara mumashanyarazi menshi ugomba kuba munini cyane kuruta umubare wibyobo hejuru yumurongo wa valence mumbaraga nkeya hagati yuturere twombi twingufu kugirango tugere kuri inversion ya inomero. Ibi bigerwaho mugukoresha kubogama kwiza kuri homojunction cyangwa heterojunction no gutera inshinge zikenewe murwego rukora kugirango ushimishe electron ziva mumashanyarazi yo hepfo ya valence kumurongo wo hejuru utwara ingufu. Iyo umubare munini wa electron mubice byahinduwe byabaturage bigahurira hamwe nibyobo, imyuka ihumanya iba.
2. Kugirango ubone imirasire ikangura, imirasire ikangurwa igomba kugaburirwa inshuro nyinshi muri resonator ya optique kugirango ihindurwe na lazeri, resonator ya lazeri ikorwa nubuso busanzwe bwa kirisiti ya kirimbuzi nkindorerwamo, mubisanzwe ushyizwe kumpera yumucyo hamwe na firime ndende ya dielectric yerekana ibintu byinshi, kandi ubuso bunoze bushyizwe hamwe na firime yagabanutse. Kuri cavit ya Fp (Fabry-Perot cavity) ya semiconductor laser, cavit ya FP irashobora kubakwa byoroshye ukoresheje indege ya clavage naturel perpendicular kuri indege ya pn ihuza kirisiti.
. umurima woroshye mu cyuho. Ibi bigomba kugira inshinge zikomeye zihagije, ni ukuvuga ko hariho umubare uhagije wimibare ihindagurika, niko urwego rwo hejuru rwimibare ihindagurika, niko inyungu nyinshi, ni ukuvuga, ibisabwa bigomba kuba byujuje ibyangombwa byateganijwe. Iyo lazeri igeze kumuryango, urumuri rufite uburebure bwihariye burashobora kumvikana mu cyuho kandi rukongerwamo imbaraga, hanyuma rugakora lazeri kandi ikomeza gusohoka.

Ibisabwa
1. Imbere yahinduwe imbere (laser yahinduwe) ikwiranye nimirima itandukanye mu itumanaho rya fibre optique kubera kohereza umuvuduko mwinshi hamwe nigiciro gito.
2. Ibiranga Spectral nibiranga modulation: Semiconductor yagabanije ibitekerezo (Laser) babaye isoko yingenzi yumucyo mubitumanaho bya fibre optique no gutumanaho umwanya wa optique kuberako biranga ibintu byiza cyane biranga ibintu.
3. Igiciro n’umusaruro rusange: Lazeri ya Semiconductor igomba kuba ifite ibyiza byigiciro gito n’umusaruro mwinshi kugirango uhuze ibikenerwa n’umusaruro munini n’ibisabwa.
