Izinto okufanele uzicabangele ngokuklamai-laser ye-semiconductor enamandla aphezulu
Lesi sihloko sizochaza ngokuhlelekile izinto eziyinhloko ezicatshangelwayo zokuklama kanye nezindlela zokusebenzisa i-semiconductor enamandla amakhulu.i-laserNgokusekelwe emcabangweni ojwayelekile "wokwandisa umkhawulo wamandla aphezulu ngokwandisa ivolumu ekhanyayo, ukuthuthukisa izindlela zokuguqulwa kwamandla kanye nokuhlakazeka ngenkathi kugwenywa umonakalo omkhulu wokukhanya (i-COD)", kwenziwa ukuhlaziywa okujulile kusuka ezicini ezingu-9 ezibalulekile:
1. Indawo yokukhipha ugesi ebanzi: Ngokusebenzisa isakhiwo sendawo ebanzi (njengokwandisa ububanzi bendawo yokukhipha ugesi W kusuka kuma-micrometer ambalwa kuya kuma-micrometer angu-50-200), amandla okukhipha aphezulu angakhushulwa ngokuqondile, okuyindlela eyisisekelo yokuthola ukukhishwa kweshubhu elilodwa ezingeni lama-watt noma ngisho namashumi ama-watt, kodwa kunciphisa ikhwalithi yokukhanya.
2. Umgodi omude: Ukwandisa ubude bomgodi kuyisihluthulelo sokuthuthukisa ukusebenza kokushisa kukagesi nokufeza ukusebenza okuphumelelayo nokunamandla aphezulu. Ingqikithi yayo isekelwe ekunciphiseni ngempumelelo ukumelana nokushisa kanye nokumelana kwedivayisi, ngaleyo ndlela icindezele ukunyuka kwezinga lokushisa kwe-active region junction, inciphise imiphumela yokugcwala kwamandla, kanye nokuthuthukisa amandla okukhipha kanye nokusebenza kahle.
3. Ukwandisa ama-waveguides kanye nemigodi ye-optical engalingani: Ngokwandisa ukusatshalaliswa kwensimu ye-optical (njengokusebenzisa izakhiwo ze-optical ezingalingani), ukugqagqana phakathi kwensimu ye-optical kanye nezindawo zokulahlekelwa okukhulu kokumuncwa kungancishiswa, kunciphise kakhulu ukulahlekelwa kwangaphakathi, kuthuthukise ukusebenza kahle kwe-quantum, futhi kunciphise ukukhiqizwa kokushisa. Ngesikhathi esifanayo, ikhwalithi ye-beam ohlangothini oluqondile nayo ingathuthukiswa.
4. Isici Sokugcwalisa: Kumadivayisi ebha, isici sokugcwalisa (isilinganiso sobubanzi obuphelele beyunithi ekhipha ukukhanya nobubanzi obuphelele bebha) yipharamitha eyinhloko yokulinganisa ubukhulu bamandla okukhipha kanye nobunzima bokuphathwa kokushisa. Isici sokugcwalisa okuphezulu kuletha ubunzima bamandla aphezulu kodwa sidinga ukushabalaliswa kokushisa okuphezulu kakhulu, kuyilapho isici sokugcwalisa esincane sisiza kakhulu ekuphathweni kokushisa futhi sithuthukisa ukuthembeka.
6. Ubuchwepheshe bokuvikela ubuso: Ukuthuthukisa umkhawulo womonakalo wesibuko obonakalayo oyingozi (i-COMD) wobuso bokuphela kuyisihluthulelo sokudabula imbobo yamandla. Lesi sihloko sichaza kabanzi ngobuchwepheshe obuthathu obuyinhloko:
6.1 Ukwembozwa kanye nokwembozwa kobuso besikhala: Ngokubeka izendlalelo zokwembozwa kanye nokwembozwa kwamafilimu okubonakalisa okuphezulu/okumelana nokukhanya, amaphutha obuso besikhala ayasuswa, ukuhlanganiswa okungenamisebe kuyacindezelwa, futhi umkhawulo we-COMD uthuthukiswa kakhulu.
6.2 Ubuchwepheshe befasitela elingamunci: Ukusebenzisa i-quantum well hybridization kanye namanye amasu ukwakha indawo yefasitela ecacile ebusweni bokugcina ukuze kuncishiswe ukumuncwa kokukhanya futhi kuvinjelwe i-COMD.
6.3 Ubuchwepheshe bendawo engajovi ebusweni besikhala: Faka indawo yamanje engajovi eduze kobuso besikhala ukuze unciphise ukugcwala komthwali kanye nokuhlangana okungashisi kwemisebe ebusweni besikhala.
7. Umklamo wokukhanya okuphezulu: Kuqalwa amasu amabili okuthola ukukhanya okuphezulu ukuze kuxazululwe inkinga yekhwalithi yokukhanya ephansi ku-laser yendawo ebanzi:
7.1. Isakhiwo sekhoni: Ngokuhlanganisa "indawo yembewu" ye-waveguide encane engxenyeni engaphambili kanye "nendawo yokukhulisa ikhoni" engxenyeni engemuva, ikhwalithi yogongolo eseduze nomkhawulo wokuphambuka iyagcinwa ngenkathi kwandiswa amandla.
7.2 Ukulawula imodi: Ukwethula izakhiwo ezincane ngaphakathi kobubanzi obubanzi ukuze kwandiswe ngokukhetha ukulahleka kwezindlela eziguquguqukayo eziphezulu, ngaleyo ndlela kuthuthukiswe ikhwalithi yemisebe.
8. Umthombo we-quantum wokucindezela kanye nesinxephezelo sokucindezeleka: Ukwethula ukucindezeleka esifundeni esisebenzayo somthombo we-quantum kungenza ngcono isakhiwo sebhendi, kuthuthukise inzuzo yokwehluka, ngaleyo ndlela kuncishiswe umkhawulo wamanje, kuthuthukiswe ukusebenza kahle, futhi kuthuthukiswe izici zokushisa okuphezulu. Ubuchwepheshe bokunciphisa ukucindezeleka buvimbela ukuqongelela kokucindezeleka kanye nokukhubazeka ngokukhulisa izingqimba zezithiyo ezinokucindezeleka okuphambene, kuqinisekiswe ikhwalithi yezinto ezibonakalayo.
9. Ukuphathwa kokushisa okuthuthukisiwe kanye nokupakisha okuphansi kokucindezeleka: Ngokuphendula izinselele zokushabalalisa ukushisa ezilethwa ukuminyana kwamandla aphezulu, lesi sihloko sethula izinto ezintsha zokushisisa ukushisa (njengezinto ezihlanganisiwe zedayimane), ama-microchannel coolers, kanye nobuchwepheshe bokupakisha kusetshenziswa izinto eziphansi zokuxhumeka ukuze kufezwe amandla okushisa aphezulu kakhulu futhi kuthuthukiswe ukuthembeka.
10. Umhlahlandlela we-wave osabalalisiwe: Njengesikimu sokuphathwa kokushisa okungaphakathi kwe-chip level, lesi sakhiwo sihlukanisa umhlahlandlela we-ridge ube yindawo yokuvuselela kanye nendawo yokusabalalisa ukushisa engashintshi ngobude bomgodi, futhi sakha isiteshi sokushisa esiphambene ngaphakathi kwe-chip ukuze sisuse ukushisa ngempumelelo, sidabule imikhawulo yezindlela zendabuko zokusabalalisa ukushisa.
Isifinyezo kanye nombono obonakalayo kukhomba ukuthi ukwakheka kwamandla aphezului-laser ye-semiconductorkuyinkinga yokwenza ngcono enezinhloso eziningi ehilela ugesi, i-optics, i-thermodynamics, kanye nokuthembeka. Kuyadingeka ukufeza ibhalansi engcono kakhulu phakathi kwemiklamo emithathu eyisisekelo yendawo ebanzi yokukhipha ugesi, umgodi omude, kanye nomhlahlandlela wamagagasi obanzi, kanye nobuchwepheshe obubhekana nezinselele ezintathu ezinkulu zokuphathwa kokushisa, umonakalo wobuso bokuphela, kanye nekhwalithi yokukhanya. Ukuthuthukiswa okuqhubekayo kokusebenza kwesikhathi esizayo kuzoncika ekuthuthukisweni kwezinto ezintsha, izindlela ezintsha zomzimba, kanye nezinqubo ezintsha zokukhiqiza.
