Zoganizira za kapangidwe kakelaser ya semiconductor yamphamvu kwambiri
Nkhaniyi ifotokoza mwatsatanetsatane za kapangidwe kake ndi njira zogwiritsira ntchito semiconductor yamphamvu kwambiri.laserKutengera lingaliro lonse la "kuwonjezera malire apamwamba a mphamvu mwa kukulitsa voliyumu yowala, kukonza njira zosinthira mphamvu ndi kufalikira kwa magetsi pamene mupewa kuwonongeka kwakukulu kwa kuwala (COD)", kusanthula kwakuya kunachitika kuchokera ku mbali 9 zofunika:
1. Malo otulutsa mpweya wambiri: Pogwiritsa ntchito kapangidwe ka malo otulutsa mpweya wambiri (monga kuwonjezera m'lifupi mwa malo otulutsa mpweya W kuchokera pa ma micrometer ochepa kufika pa ma micrometer 50-200), mphamvu yayikulu yotulutsa mpweya imatha kuwonjezeredwa mwachindunji, yomwe ndi njira yoyambira yopezera kutulutsa kwa chubu chimodzi pamlingo wa watt kapena ngakhale ma watts makumi ambiri, koma imawononga khalidwe la kuwala.
2. Mphepete mwautali: Kukulitsa kutalika kwa mphepete mwautali ndiye chinsinsi chowongolera magwiridwe antchito amagetsi otenthetsera ndikupeza magwiridwe antchito abwino komanso amphamvu kwambiri. Cholinga chake chachikulu ndi kuchepetsa bwino kukana kutentha ndi kukana kwa chipangizocho, potero kuletsa kukwera kwa kutentha kwa malo ogwirira ntchito, kuchepetsa mphamvu yokwanira, ndikukweza mphamvu yotulutsa ndi magwiridwe antchito.
3. Kukulitsa ma waveguide ndi ma cavities a optical osafanana: Mwa kukulitsa kugawa kwa malo owonera (monga kugwiritsa ntchito mapangidwe a cavity a optical osafanana), kuyanjana pakati pa malo owonera ndi malo otaya ma absorption ambiri kungachepe, kuchepetsa kwambiri kutayika kwamkati, kukonza magwiridwe antchito a quantum, ndikuchepetsa kupanga kutentha. Nthawi yomweyo, khalidwe la kuwala kolunjika molunjika likhozanso kukonzedwa.
4. Chida Chodzaza: Mu zipangizo zoyezera, chida chodzaza (chiŵerengero cha m'lifupi wonse wa chipangizo chotulutsa kuwala ndi m'lifupi wonse wa chipangizocho) ndiye chinthu chofunikira kwambiri pakulinganiza kuchuluka kwa mphamvu yotulutsa ndi kuvutika kwa kayendetsedwe ka kutentha. Chida chodzaza kwambiri chimabweretsa kuchuluka kwa mphamvu koma chimafuna kutentha kwambiri, pomwe chida chodzaza chochepa chimalimbikitsa kwambiri kayendetsedwe ka kutentha ndipo chimawonjezera kudalirika.
6. Ukadaulo woteteza nkhope kumapeto: Kukonza malire a kuwonongeka kwa galasi la maso (COMD) pa nkhope kumapeto ndiye njira yofunika kwambiri yotulukira m'malo otsekereza magetsi. Nkhaniyi ikufotokoza za ukadaulo waukulu itatu:
6.1 Kuphimba pamwamba pa dzenje ndi kuphimba: Mwa kuyika zigawo za kuphimba ndi kuphimba mafilimu owonetsa bwino/otsutsa kuwunikira, zolakwika za pamwamba pa dzenje zimakhala zopanda kuwunikira, kubwezeretsanso kosawononga kumachepetsedwa, ndipo malire a COMD amawonjezeka kwambiri.
6.2 Ukadaulo wa zenera losayamwa: Kugwiritsa ntchito njira zosakaniza chitsime cha quantum ndi njira zina zopangira dera lowonekera la zenera kumapeto kuti muchepetse kuyamwa kwa kuwala ndikuletsa COMD.
6.3 Ukadaulo wa malo osagwiritsa ntchito jakisoni pamwamba pa malo obowola: Yambitsani malo obowola omwe sagwiritsa ntchito jakisoni pafupi ndi malo obowola kuti muchepetse kuchuluka kwa chonyamulira ndi kubwezeretsanso kwa malo obowola omwe sagwiritsa ntchito radiation pamwamba pa malo obowola.
7. Kapangidwe ka kuwala kwambiri: Njira ziwiri zopezera kuwala kwakukulu zayambitsidwa kuti zithetse vuto la kuwala koipa mu laser yapafupi:
7.1. Kapangidwe ka kononi: Pogwiritsa ntchito "malo a mbewu" opapatiza omwe ali kutsogolo ndi "malo okulitsa kononi" omwe ali kumbuyo, khalidwe la kuwala pafupi ndi malire a diffraction limasungidwa pamene mphamvu ikuwonjezeka.
7.2 Kuwongolera njira: Kuyambitsa ma microstructures mkati mwa mitundu yosiyanasiyana kuti muwonjezere kutayika kwa njira zapamwamba zopingasa, potero kukonza ubwino wa kuwala.

8. Chitsime cha quantum chophwanyika ndi kulimbitsa mphamvu: Kuyika kulimbitsa mphamvu m'dera logwira ntchito la chitsime cha quantum kungathandize kukonza kapangidwe ka gululo, kukulitsa phindu losiyana, motero kuchepetsa mphamvu yamagetsi, kukonza magwiridwe antchito, ndikuwonjezera mawonekedwe a kutentha kwambiri. Ukadaulo wolimbitsa mphamvu umaletsa kusonkhanitsa kupsinjika ndi zolakwika mwa kukulitsa zigawo zotchinga ndi kupsinjika kosiyana, kuonetsetsa kuti zinthuzo ndizabwino.
9. Kusamalira kutentha kwapamwamba komanso kulongedza zinthu zochepa: Poyankha mavuto okhudzana ndi kutayikira kutentha omwe amabwera chifukwa cha kuchuluka kwa mphamvu, nkhaniyi ikubweretsa zipangizo zatsopano zotenthetsera kutentha (monga zida za diamondi), zoziziritsira za microchannel, ndi ukadaulo wolongedza zinthu pogwiritsa ntchito zipangizo zochepa kuti zikwaniritse mphamvu yotayikira kutentha kwambiri komanso kulimbitsa kudalirika.
10. Distributed waveguide: Monga njira yoyendetsera kutentha kwa chip level, kapangidwe kameneka kamagawaniza ridge waveguide kukhala malo otulutsira kutentha ndi malo otulutsira kutentha osagwiritsa ntchito kutentha mozungulira kutalika kwa dzenje, ndipo amapanga njira yodutsa kutentha mkati mwa chip kuti ichotse kutentha bwino, ndikudutsa malire a njira zachikhalidwe zotulutsira kutentha.
Chidule ndi malingaliro zikusonyeza kuti kapangidwe ka mphamvu zazikululaser ya semiconductorNdi vuto la kukonza zinthu m'njira zosiyanasiyana lomwe limakhudza magetsi, kuwala, kutentha kwa dziko, ndi kudalirika. Ndikofunikira kuti pakhale mgwirizano wabwino pakati pa mapangidwe atatu oyambira a malo otulutsa mpweya wambiri, malo otseguka, ndi mafunde otambasuka, ndi ukadaulo womwe umalimbana ndi mavuto atatu akuluakulu okhudza kasamalidwe ka kutentha, kuwonongeka kwa nkhope, ndi mtundu wa kuwala. Kupititsa patsogolo magwiridwe antchito mtsogolo kudzadalira pakupanga zipangizo zatsopano, njira zatsopano zakuthupi, ndi njira zatsopano zopangira.
