Sarudzo YezvakanakaLaser Source: Edge EmissionSemiconductor LaserChikamu Chechipiri

4. Mamiriro ekushandisa edge-emission semiconductor lasers
Nekuda kwehupamhi hwayo hwewavelength renji uye simba repamusoro, edge-emitting semiconductor lasers yakashandiswa zvinobudirira muminda yakawanda senge mota, optical kutaurirana uye.laserkurapwa. Sekureva kwaYole Developpement, kambani ine mukurumbira pasi rese yemusika wekutsvagisa, musika-ku-emit laser musika uchakura kusvika pamabhiriyoni manomwe nemazana mana emadhora muna 2027, uine huwandu hwekukura kwepagore hwe13%. Uku kukura kucharamba kuchifambiswa nekufambiswa kwekuonana kwemaziso, senge optical modules, amplifiers, uye 3D sensing application yekutaurirana nenhare. Kune akasiyana mashandisirwo ezvinodiwa, akasiyana EEL chimiro dhizaini zvirongwa zvakagadziridzwa muindasitiri, kusanganisira: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, ekunze cavity laser (ECL) semiconductor lasers, akagovera mhinduro semiconductor lasers (DFB laser), quantum cascade semiconductor lasers (QCL), uye yakafara nzvimbo laser diodes (BALD).

Nekuwedzera kuri kuda kwekutaurirana kwemaziso, 3D sensing application uye mamwe minda, kudiwa kwema semiconductor lasers kuri kuwedzerawo. Pamusoro pezvo, edge-emitting semiconductor lasers uye vertical-cavity surface-emitting semiconductor lasers vanoitawo basa mukuzadza zvikanganiso zvemumwe nemumwe mumashandisirwo ari kubuda, akadai se:
(1) Mundima ye optical communications, iyo 1550 nm InGaAsP/InP Distributed Feedback ( (DFB laser) EEL uye 1300 nm InGaAsP/InGaP Fabry Pero EEL inowanzoshandiswa pakufambisa madaro e2 km kusvika 40 km uye transmission rates kusvika ku 40 m, 0 m. kuderera kwekutapurirana kumhanya, VCsels yakavakirwa pa850 nm InGaAs uye AlGaAs inotonga.
(2) Vertical cavity surface-emitting lasers ine zvakanakira saizi diki uye nhete yavelength, saka yakashandiswa zvakanyanya mumusika wemagetsi evatengi, uye kupenya uye simba rakanakira edge emitting semiconductor lasers inovhura nzira yekunzwa kureba maapplication uye yakakwirira-simba kugadzirisa.
(3) Ese ari maviri eed-emitting semiconductor lasers uye vertical cavity surface-emitting semiconductor lasers anogona kushandiswa kwenguva pfupi - uye yepakati-renji liDAR kuita chaiwo maapplication akadai sekuona mapofu uye kusimuka kwenzira.

5. Kubudirira kweramangwana
Iyo yekumucheto emitting semiconductor laser ine zvakanakira kuvimbika kwepamusoro, miniaturization uye yakakwira inopenya simba density, uye ine yakafara tarisiro yekushandisa mu optical kutaurirana, liDAR, zvekurapa nezvimwe minda. Nekudaro, kunyangwe iyo nzira yekugadzira yeedge-emitting semiconductor lasers yave yakakura, kuitira kuti isangane nekukura kuri kuda kwemaindasitiri nevatengi misika yeedge-emitting semiconductor lasers, zvinodikanwa kuenderera mberi nekukwirisa tekinoroji, maitiro, mashandiro uye zvimwe zvinhu zveedge-emitting semiconductor lasers, kusanganisira: kudzikisa mukati meiyo density. Kuderedza maitiro ekugadzirisa; Gadzira matekinoroji matsva ekutsiva echinyakare vhiri uye blade wafer yekucheka maitiro ayo anowanzo kuunza hurema; Gadzirisa iyo epitaxial chimiro kuti uvandudze kugona kwe edge-emitting laser; Deredza mari yekugadzira, nezvimwe. Pamusoro pekuwedzera, nekuti chiedza chinobuda chemupendero-emitting laser chiri padivi remupendero we semiconductor laser chip, zvakaoma kuwana diki-saizi chip packaging, saka iyo inoenderana yekurongedza nzira ichiri kuda kuwedzeredzwa.
