Intangiriro Kuri Edge Emitting Laser (EEL)

Intangiriro Kuri Edge Emitting Laser (EEL)
Kugirango tubone imbaraga nyinshi za semiconductor laser isohoka, tekinoroji iriho ni ugukoresha imiterere y’ibyuka bihumanya. Rezonator ya lazeri isohora igice cya semiconductor igizwe nubuso busanzwe bwo gutandukana bwa kirisiti ya semiconductor, kandi urumuri rusohoka rusohoka ruva kumpera yimbere ya lazeri. Ubwoko bwa semiconductor lazeri burashobora kugera kumasoko menshi, ariko aho busohokera ni elliptique, ubwiza bwibiti bukenera guhinduka.
Igishushanyo gikurikira cyerekana imiterere ya lazeri isohora igice cya kabiri. Umuyoboro wa optique wa EEL urasa nubuso bwa chip ya semiconductor kandi ugasohora lazeri kumpera ya chip ya semiconductor, ishobora kumenya umusaruro wa laser ufite imbaraga nyinshi, umuvuduko mwinshi n urusaku ruke. Nyamara, laser beam isohoka na EEL mubusanzwe ifite ibice bitamenyerewe kandi bitandukanijwe, kandi guhuza neza hamwe na fibre cyangwa ibindi bikoresho bya optique biri hasi.

Ubwiyongere bwimbaraga za EEL bugarukira kubushuhe bwimyanda mukarere gakorera hamwe no kwangirika kwa optique hejuru yubutaka. Mu kongera agace ka waveguide kugirango ugabanye ubushyuhe bwimyanda mukarere gakora kugirango iterambere ryogukwirakwiza ubushyuhe, kongera ubuso bwumucyo kugirango ugabanye ingufu za optique yumurambararo kugirango wirinde kwangirika kwa optique, ingufu ziva kuri miliwatt zigera kuri magana zirashobora kugerwaho muburyo bumwe bwo guhinduranya uburyo bwo guhinduranya.
Kuri 100mm ya waveguide, lazeri imwe isohora impande zose zishobora kugera kuri watt mirongo yingufu zisohoka, ariko muriki gihe umurongo wa waveguide ni uburyo bwinshi cyane ku ndege ya chip, kandi igipimo cy’ibice bisohoka nacyo kigera kuri 100: 1, bisaba sisitemu yo gushiraho ibiti bigoye.
Hashingiwe ko nta terambere rishya ryakozwe mu ikoranabuhanga ry’ibikoresho ndetse n’ikoranabuhanga ryiyongera rya epitaxial, inzira nyamukuru yo kuzamura ingufu ziva mumashanyarazi imwe ya semiconductor laser ni ukongera ubugari bwibice by'akarere ka chip. Nyamara, kongera ubugari bwumurongo muremure cyane biroroshye kubyara transvers yo murwego rwohejuru rwuburyo bwo guhindagurika hamwe na filament imeze nka oscillation, bizagabanya cyane uburinganire bwumucyo usohoka, kandi imbaraga zisohoka ntiziyongera ugereranije nubugari bwumugozi, bityo imbaraga zisohoka za chip imwe ni nto cyane. Kugirango tunoze cyane imbaraga zisohoka, tekinoroji ya array ibaho. Ikoranabuhanga rihuza ibice byinshi bya lazeri kumurongo umwe, kuburyo buri gice gisohora urumuri rutondekanye nkumurongo umwe ugizwe nicyerekezo cyerekezo cyihuta, mugihe cyose tekinoloji ya optique yo kwigunga ikoreshwa mugutandukanya buri gice cyohereza urumuri mumurongo, kugirango bitavangavanga hagati yacyo, bigakora imbaraga nyinshi ziva mumashanyarazi. Iyi semiconductor laser chip ni chip ya semiconductor laser array (LDA) chip, izwi kandi nka semiconductor laser bar.
