4. Ngwa ọnọdụ nke ihu-emission semiconductor lasers
N'ihi oke ogologo ogologo ya na ike dị elu, a na-etinye laser semiconductor lasers nke ọma n'ọtụtụ mpaghara dịka ụgbọ ala, nkwurịta okwu anya nalaserọgwụgwọ ọgwụgwọ. Dabere na Yole Developement, ụlọ ọrụ nyocha ahịa ama ama n'ụwa niile, ahịa laser nke na-emepe emepe ga-eto $ 7.4 ijeri na 2027, yana ọnụ ọgụgụ uto kwa afọ nke 13%. A ga-aga n'ihu na-akwalite uto a site na nkwukọrịta ngwa anya, dị ka modul anya, amplifiers, na ngwa nhụta 3D maka nkwukọrịta data na nkwukọrịta. Maka ngwa dị iche iche a chọrọ, a na-emepụta atụmatụ nhazi EEL dị iche iche na ụlọ ọrụ ahụ, gụnyere: Fabripero (FP) lasers semiconductor lasers, Bragg Reflector (DBR) nkesa nkesa, laser cavity laser (ECL), laser semiconductor lasers, na-ekesa nzaghachi semiconductor lasers.DFB laser) , quantum cascade semiconductor lasers (QCL), na obosara mpaghara laser diodes (BALD).

Site na mmụba na-arịwanye elu maka nkwurịta okwu anya, ngwa nhụta 3D na mpaghara ndị ọzọ, ọchịchọ maka lasers semiconductor na-abawanye. Tụkwasị na nke ahụ, lasers semiconductor lasers na vertical-cavity surface-emitting semiconductor lasers na-ekerekwa òkè n'imejupụta mmejọ ibe ha na ngwa ndị na-apụta, dị ka:
(1) N'ihe gbasara nkwukọrịta ngwa anya, 1550 nm InGaAsP / InP Distributed Feedback (DFB laser) EEL na 1300 nm InGaAsP / InGaP Fabry Pero EEL na-ejikarị na ebe nnyefe nke 2 km na 40 km na ọnụego nnyefe ruo ruo 40 Gbps, Otú ọ dị, na 60 m ruo 300 m nnyefe anya na obere nnyefe ọsọ, VCsels dabeere na 850 nm InGaAs na AlGaAs bụ ndị kasị.
(2) Vetikal oghere elu-emitting lasers nwere uru nke obere nha na warara wavelength, ya mere, a na-eji ha n'ọtụtụ ebe n'ahịa eletrọnịkị ndị na-azụ ahịa, na nchapụta na uru ike nke ihu na-emitting semiconductor lasers na-emeghe ụzọ maka ngwa nhụta anya na nhazi ike dị elu.
(3) Enwere ike iji lasers semiconductor abụọ na-emitting ọnụ na oghere oghere elu-emitting semiconductor lasers maka mkpụmkpụ - na ọkara liDAR iji nweta ngwa ụfọdụ dị ka nchọpụta ntụpọ kpuru na ọpụpụ ụzọ.

5. Ọdịnihu mmepe
Igwe na-egosiputa semiconductor laser nwere uru nke ntụkwasị obi dị elu, miniaturization na njupụta ike dị elu, ma nwee atụmanya ngwa sara mbara na nkwukọrịta ngwa anya, liDAR, ahụike na mpaghara ndị ọzọ. Otú ọ dị, ọ bụ ezie na usoro mmepụta nke laser semiconductor lasers na-emepe emepe ka tozuru oke, iji mezuo ọchịchọ na-arịwanye elu nke ụlọ ọrụ mmepụta ihe na ndị ahịa maka lasers semiconductor lasers, ọ dị mkpa iji nọgide na-ebuli teknụzụ, usoro, arụmọrụ na ndị ọzọ. akụkụ nke lasers semiconductor nke na-ekupụ ọnụ, gụnyere: ibelata njupụta ntụpọ n'ime wafer; Belata usoro usoro; Zụlite teknụzụ ọhụrụ iji dochie wiilịgharị ọdịnala ọdịnala na usoro igbutu agụba na-adịkarị mfe iwebata ntụpọ; Na-ebuli ihe owuwu epitaxial iji melite arụmọrụ nke laser eti-emitting; Belata ụgwọ ọrụ mmepụta ihe, wdg. Tụkwasị na nke ahụ, n'ihi na ọkụ mmepụta nke laser na-egbuke egbuke dị n'akụkụ akụkụ nke mgbawa laser semiconductor, ọ na-esiri ike iji nweta obere ngwugwu mgbawa, ya mere usoro nkwakọ ngwaahịa metụtara ka kwesịrị ịdị. agbajikwa ọzọ.
