Cov thev naus laus zis ntawm cov tshuab hluav taws xob uas siv hluav taws xob ntau ntawm cov tshuab hluav taws xob muaj xws li tshuab kev loj hlob ntawm cov khoom siv hluav taws xob semiconductor laser chips, ntim thiab kho qhov muag kom pom tseeb ntawm semiconductor laser chips, laser beam shaping technology thiab laser technology kev sib xyaw.
Lub epitaxial txoj kev loj hlob technology ntawm semiconductor laser tej daim, cov kev tshawb fawb thiab tsim ntawm epitaxial nti lug ua si ib qho tseem ceeb heev luag hauj lwm nyob rau hauv txoj kev loj hlob ntawm high-power semiconductor lasers, thiab yog li ntawd yog cov ua kom pom tseeb ntawm kev tshawb fawb nyob rau hauv high-power semiconductor laser tshuab.
Nyob rau hauv xyoo tsis ntev los, cov kws txawj muaj ntxiv dag zog rau cov kev tshawb fawb nyob rau hauv peev no technology thiab ua muaj kev nruam ntej.
Nws cov kev tshawb fawb tsis ntev los no feem ntau tau hais raws li hauv qab no:
1 Kev siv cov khoom siv aluminium-thaj chaw ua hauj lwm zoo ua kom muaj qhov muaj zog ntawm lub qhov muag pom kev puas tsuaj ntawm qhov teeb meem kev puas tsuaj lub laser kawg lub ntsej muag, kom lub zog tsim tawm thiab kev pab cuam lub neej ntawm lub cuab yeej laser tau zoo dua;
2 Siv lub strained quantum zoo qauv, lub photoelectric kev kawm ntawm cov muaj hwj huam semiconductor laser yog zoo zoo, cov emission wavelength khwv ntawm lub GaAs-raws li cov ntaub ntawv uas system txhab, thiab tus Harbor tam sim no ceev ntawm lub ntaus ntawv yog txo;
3 Cov kab noj hniav loj kho qhov muag ua qauv tsim qauv siv dav waveguide ua rau lub nqaj loj hauv qhov chaw ze, uas txo cov zis laser fais fab ntom ntom ntawm lub cuab yeej, ua rau kom muaj zog tawm thiab tawm zog ntawm lub laser, thiab tseem ua rau lub cuab yeej lub neej txuas ntxiv.
Tam sim no, kev hloov pauv ntawm electro-optical ua tau zoo ntawm kev ua lag luam semiconductor laser chips tau mus txog 60%, thiab lub tshuab hluav taws xob electro-optical hloov dua siab tshiab ntawm cov khoom siv hauv chav kuaj mob tau ncav ntau dua 70%. Nws yog ntseeg hais tias nrog lub ntxiv kev txhim kho ntawm nws cov technology. Tsis ntev tom ntej no, kev siv hluav taws xob ntawm kev siv hluav taws xob ntau ntawm semiconductor laser chips yuav ncav cuag ntau dua 85%.
