Filifiliga o puna sili leisa: pito emission semiconductor laser Vaega Muamua

Filifiliga leleipuna laser: pito emission semiconductor laser
1. Folasaga
Semiconductor laserua vaevaeina tupe meataalo i pito emitting leisa meataalo (EEL) ma luga o le lua i luga emitting leisa meataalo (VCSEL) e tusa ai ma le faagasologa o gaosiga eseese o resonators, ma o latou eseesega fausaga faʻaalia o loʻo faʻaalia i le Ata 1. Faʻatusatusa i luga o le lua i luga ole laisa, pito. emitting semiconductor leisa atinae faatekonolosi e sili atu le matua, faatasi ai ma se lautele galu umi, maualugafaaeletonikafa'aliliuga lelei, malosi tele ma isi fa'amanuiaga, e fetaui lelei mo le fa'aogaina o le laser, feso'ota'iga fa'apitoa ma isi matā'upu. I le taimi nei, o lasers semiconductor mata-emitting o se vaega taua o le alamanuia optoelectronics, ma o latou talosaga ua ufitia alamanuia, fesootaiga, faasaienisi, tagata faatau, militeri ma aerospace. Faatasi ai ma le atinaʻeina ma le alualu i luma o tekinolosi, ua matua faʻaleleia atili le malosi, faʻatuatuaina ma le malosi o le liua o lasers semiconductor edge-emitting, ma o latou faʻamoemoega talosaga e sili atu ma sili atu ona lautele.
O le isi, o le a ou taʻitaʻia oe e faʻafetai atili i le uiga ese o le faʻaogaina o le itusemiconductor lasers.

Ata 1 (tauagavale) leisa fa'avevela semiconductor ma (taumatau) fa'alava tu'usa'o i luga o le ata fa'auluina leisa.

2. Ta'iala galue ole pito emission semiconductorleisa
O le fausaga o le pito-emitting leisa semiconductor e mafai ona vaevaeina i vaega nei e tolu: semiconductor vaega galue, puna puna ma resonator opitika. E ese mai i le resonators o le pito i luga o le pito i luga o le pito i luga-emitting lasers (lea e aofia ai le pito i luga ma lalo Bragg faʻata), o le resonators i pito-emitting semiconductor laser masini e tele lava e aofia ai ata tifaga i itu uma e lua. O le fausaga masani o le masini EEL ma le fausaga o le resonator o loʻo faʻaalia i le Ata 2. O le photon i le pito-emission semiconductor laser masini e faʻateleina e ala i le filifilia o auala i le resonator, ma o le laser ua faia i le itu e tutusa ma le substrate surface. Edge-emitting semiconductor laser masini o loʻo i ai le tele o faʻaogaina o galu umi ma e talafeagai mo le tele o faʻaoga aoga, o lea e avea ai ma se tasi o punaʻoa sili ona lelei.

O fa'ailoga o le iloiloga o fa'atinoga o laisa semiconductor mata-emitting e tutusa ma isi lasers semiconductor, e aofia ai: (1) leisa lasing umi galu; (2) Ith Ith, o lona uiga, o le taimi nei lea e amata ai e le laser diode ona gaosia le laser oscillation; (3) Iop galue i le taimi nei, o lona uiga, o le avetaʻavale o loʻo i ai nei pe a oʻo atu le laser diode i le mana faʻatulagaina, e faʻaaogaina lenei parakalafa i le mamanu ma le faʻaogaina o le taʻavale laser; (4) Fa'ata'atiaga lelei; (5) Fe'ese'esega tu'usa'o Angle θ⊥; (6) Fe'ese'esega fa'asaga i le Angle θ∥; (7) Mataʻituina le Im o loʻo iai nei, o lona uiga, o le tele o loʻo iai nei o le semiconductor laser chip i le mana faʻatulagaina.

3. Su'esu'ega alualu i luma o GaAs ma GaN fa'avae pito emitting semiconductor lasers
O le laser semiconductor e faʻavae i luga o mea semiconductor GaAs o se tasi lea o tekinolosi laser semiconductor sili ona matua. I le taimi nei, GAAS-fa'avae latalata-infrared bands (760-1060 nm) pito-emitting semiconductor lasers ua fa'aaogaina fa'apisinisi. I le avea ai o le lona tolu o augatupulaga semiconductor mea ina ua uma Si ma GaAs, GaN ua matua popole i suesuega faasaienisi ma alamanuia ona o lona tulaga lelei faaletino ma vailaau. Faatasi ai ma le atinaʻeina o masini optoelectronic faʻavae GAN ma taumafaiga a tagata suʻesuʻe, GAN-faʻavae moli-emitting diodes ma pito-emitting lasers ua faʻapisinisi.
