Intangiriro kuri Laser Isohora Umucyo (EEL)

Intangiriro kuri Laser Isohora Umucyo (EEL)
Kugira ngo haboneke umusaruro wa laser ya semiconductor ifite imbaraga nyinshi, ikoranabuhanga ririho ubu ni ugukoresha imiterere y’imyotsi yo mu nkombe. Resonator ya laser ya semiconductor ikora mu nkombe igizwe n’ubuso bw’umwimerere bwa kristu ya semiconductor, kandi urumuri rusohoka ruturutse ku mpera y’imbere ya laser. Laser ya semiconductor yo mu bwoko bwa emission yo mu nkombe ishobora gutanga umusaruro mwinshi, ariko aho isohora ni nk’ibara ry’umurambararo, ubwiza bw’urumuri ni bubi, kandi imiterere y’urumuri igomba guhindurwa hakoreshejwe sisitemu yo gushushanya urumuri.
Ishusho ikurikira igaragaza imiterere ya laser ya semiconductor isohora imipaka. Umwobo w'urumuri wa EEL uteganye n'ubuso bwa chip ya semiconductor kandi usohora laser ku nkengero za chip ya semiconductor, ishobora gutanga umusaruro wa laser ku ngufu nyinshi, umuvuduko mwinshi n'urusaku ruto. Ariko, umusaruro wa laser wa EEL muri rusange ufite igice cy'urumuri kidasa n'urusaku runini, kandi ubushobozi bwo guhuza fibre cyangwa ibindi bice by'urumuri ni buke.

Ubwiyongere bw'ingufu zisohoka za EEL bugengwa no kwibumbirana kw'ubushyuhe bw'imyanda mu gace kari mu bikorwa ndetse no kwangirika kw'urumuri ku buso bwa semiconductor. Mu kongera agace kayobora umuraba kugira ngo ugabanye ukwibumbirana kw'ubushyuhe bw'imyanda mu gace kari mu bikorwa kugira ngo hongerwe uburyo ubushyuhe bukwirakwira, kongera agace karasohokamo urumuri kugira ngo ugabanye ubucucike bw'ingufu zisohoka z'urumuri kugira ngo hirindwe kwangirika kw'urumuri, imbaraga zisohoka zigera kuri miliwati amagana zishobora kugerwaho mu buryo bumwe bwa transverse mode waveguide.
Kuri 100mm waveguide, laser imwe isohora imipaka ishobora kugera kuri watts icumi z'ingufu zo gusohora, ariko muri iki gihe waveguide ifite uburyo bwinshi cyane ku murongo wa chip, kandi igipimo cy'umuvuduko w'umuvuduko nacyo kigera kuri 100: 1, gisaba sisitemu igoye yo gushushanya imirasire.
Dushingiye ku kuba nta terambere rishya ririho mu ikoranabuhanga ry’ibikoresho n’ikoranabuhanga ryo gukura kwa epitaxial, uburyo bw’ingenzi bwo kunoza imbaraga zo gusohora za chip imwe ya laser ya semiconductor ni ukongera ubugari bw’umurongo w’agace k’urumuri rwa chip. Ariko, kongera ubugari bw’umurongo hejuru cyane biroroshye gutanga oscillation yo mu buryo bwo hejuru no oscillation nk’iya filament, bizagabanya cyane uburinganire bw’urumuri, kandi imbaraga zo gusohora ntiziyongere ukurikije ubugari bw’umurongo, bityo imbaraga zo gusohora za chip imwe ni nke cyane. Kugira ngo wongere cyane imbaraga zo gusohora, ikoranabuhanga rya array riratangira kubaho. Iri koranabuhanga rihuza ibice byinshi bya laser kuri substrate imwe, ku buryo buri gice gitanga urumuri gishyizwe ku murongo nk’umurongo umwe mu cyerekezo gito, igihe cyose ikoranabuhanga rya optique isolation rikoreshwa mu gutandukanya buri gice gitanga urumuri muri array, kugira ngo bitabangamirana, bigatuma habaho multi-aperture lasing, ushobora kongera imbaraga zo gusohora za chip yose wongera umubare w’ibice bitanga urumuri byahujwe. Iyi chip ya laser ya semiconductor ni chip ya laser ya semiconductor array (LDA), izwi kandi nka bar ya laser ya semiconductor.
