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. Rononator ya lazeri isohora igice cya semiconductor laser igizwe nubuso busanzwe bwo gutandukana bwa kirisiti ya semiconductor, kandi urumuri rusohoka rusohoka kuva kumpera yimbere ya lazeri. Ubwoko bwa semiconductor lazeri burashobora kugera kumasoko menshi, ariko Ibisohoka ni elliptique, ubwiza bwibiti ni bubi, kandi imiterere yibiti igomba guhinduka hamwe na sisitemu yo gushiraho ibiti.
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 utezimbere ubushyuhe, kongera urumuri rusohoka kugirango ugabanye ingufu za optique yumurambararo kugirango wirinde kwangirika kwa optique, ingufu zisohoka zigera kuri miliwatt magana zirashobora kugerwaho muburyo bumwe bwo guhinduranya imiterere ya waveguide.
Kuri 100mm ya waveguide, lazeri imwe isohora impande zose zishobora kugera kuri watts icumi zingufu ziva hanze, ariko muriki gihe umurongo wogide ni uburyo bwinshi cyane muburyo bwindege ya chip, kandi igipimo cyibisohoka nacyo kigera kuri 100: 1, bisaba sisitemu igoye.
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 no guhindagurika nka filament, bizagabanya cyane uburinganire bwumucyo usohoka, kandi imbaraga zisohoka ntiziyongera ugereranije nubugari bwumurongo, bityo imbaraga zisohoka za chip imwe imwe ni nto cyane. Kugirango tunoze cyane imbaraga zisohoka, tekinoroji ya array ibaho. Ikoranabuhanga rihuza ibice byinshi bya lazeri kumurongo umwe, kuburyo buri gice cyohereza urumuri gitondekanye nkumurongo umwe ugereranya icyerekezo cyihuta, mugihe cyose tekinoroji yo kwigunga ikoreshwa mugutandukanya buri gice gisohora urumuri murwego , kugirango batabangamirana, bagakora laseri nyinshi-aperture, urashobora kongera imbaraga ziva muri chip yose wongera umubare wibice bisohora urumuri. Iyi semiconductor laser chip ni chip ya semiconductor laser array (LDA) chip, izwi kandi nka semiconductor laser bar.
