4. Ọnọdụ ngwa nke laser semiconductor emission nke dị n'akụkụ
N'ihi oke ogologo ya na ike dị elu ya, ejirila laser semiconductor na-ewepụta n'akụkụ mee ihe nke ọma n'ọtụtụ ebe dịka ụgbọala, nkwukọrịta anya nalaserọgwụgwọ ahụike. Dịka Yole Developmentpement, ụlọ ọrụ nyocha ahịa ama ama n'ụwa niile si kwuo, ahịa laser nke na-aga n'ihu ruo na mwepụta ga-eto ruo ijeri $7.4 na 2027, yana ọnụego uto kwa afọ nke 13%. Mmụba a ga-aga n'ihu na-akwalite site na nkwukọrịta anya, dị ka modulu optical, amplifiers, na ngwa mmetụta 3D maka nkwukọrịta data na nkwukọrịta. Maka ihe dị iche iche achọrọ maka ngwa, emepụtala atụmatụ nhazi EEL dị iche iche na ụlọ ọrụ ahụ, gụnyere: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, external cavity laser laser (ECL) semiconductor lasers, distributed feedback semiconductor lasers (Laser DFB) , lasers semiconductor nke quantum cascade (QCL), na diode laser sara mbara (BALD).

Ka ọchịchọ maka nkwukọrịta anya na-arị elu, ngwa nchọpụta 3D na mpaghara ndị ọzọ na-abawanye, ọchịchọ maka laser semiconductor na-amụbakwa. Na mgbakwunye, laser semiconductor na-ewepụta n'akụkụ na laser semiconductor na-ewepụta n'elu oghere kwụ ọtọ na-arụkwa ọrụ n'imeju adịghị ike nke ibe ha na ngwa ndị na-apụta, dịka:
(1) N'ihe gbasara nkwukọrịta anya, a na-ejikarị 1550 nm InGaAsP/InP Distributed Feedback ((DFB laser) EEL na 1300 nm InGaAsP/InGaP Fabry Pero EEL eme ihe n'ebe dị anya site na kilomita 2 ruo kilomita 40 na ọnụego nnyefe ruo 40 Gbps. Agbanyeghị, na ebe dị anya site na mita 60 ruo mita 300 na obere ọsọ nnyefe, VCsels dabere na 850 nm InGaAs na AlGaAs bụ ndị kacha.
(2) Laser ndị na-ewepụta oghere dị n'elu oghere kwụ ọtọ nwere uru nke obere nha na ogologo ogologo dị warara, yabụ ejirila ha nke ọma n'ahịa eletrọniki ndị ahịa, na uru nke ìhè na ike nke laser semiconductor na-ewepụta n'akụkụ na-eme ka ụzọ dị mfe maka ngwa nchọpụta anya na nhazi ike dị elu.
(3) Enwere ike iji laser semiconductor nke na-ewepụta n'akụkụ na laser semiconductor nke na-ewepụta n'elu oghere kwụ ọtọ maka obere na ọkara-oke liDAR iji nweta ngwa ndị dị mkpa dịka nchọpụta ntụpọ kpuru ìsì na ọpụpụ ụzọ.

5. Mmepe n'ọdịnihu
Laser semiconductor nke na-ewepụta ihe n'ọnụ nwere uru dị na ntụkwasị obi dị elu, obere mmepụta na nnukwu njupụta ike na-enwu enwu, ma nwee nnukwu ohere itinye ya n'ọrụ na nkwukọrịta anya, liDAR, ahụike na ngalaba ndị ọzọ. Agbanyeghị, ọ bụ ezie na usoro mmepụta nke laser semiconductor nke na-ewepụta ihe n'ọnụ adịla mma, iji mezuo ọchịchọ na-eto eto nke ahịa ụlọ ọrụ mmepụta ihe na ndị ahịa maka laser semiconductor nke na-ewepụta ihe n'ọnụ, ọ dị mkpa ka teknụzụ, usoro, arụmọrụ na akụkụ ndị ọzọ nke laser semiconductor nke na-ewepụta ihe n'ọnụ mgbe niile, gụnyere: ibelata njupụta ntụpọ dị n'ime wafer; Belata usoro usoro; Mepụta teknụzụ ọhụrụ iji dochie usoro ịkpụ wiil na agụba ọdịnala nke na-ebute ntụpọ; Mee ka usoro epitaxial ka mma iji melite arụmọrụ nke laser nke na-ewepụta ihe n'ọnụ; Belata ọnụ ahịa mmepụta, wdg. Na mgbakwunye, n'ihi na ọkụ mmepụta nke laser nke na-ewepụta ihe n'ọnụ dị n'akụkụ nke chip laser semiconductor, ọ na-esiri ike inweta obere ngwugwu chip, yabụ usoro nkwakọ ngwaahịa metụtara ya ka kwesịrị ịgbasa ọzọ.
