Ukunemba kwe-Component Machining
Izihlungi ze-High-Q zidinga ukunemba okuphezulu kakhulu ekwenzeni ingxenye. Ngisho nokuchezuka okuncane ngosayizi, umumo, noma indawo kungathinta kakhulu ukusebenza kwesihlungi kanye ne-Q-factor. Isibonelo, ezihlungini ze-cavity, ubukhulu kanye nobukhulu obungaphezulu be-cavity kuthinta ngokuqondile i-Q-factor. Ukuze kuzuzwe i-Q-factor ephezulu, izingxenye kufanele zenziwe ngomshini ngokunemba okuphezulu, ngokuvamile okudinga ubuchwepheshe bokukhiqiza obuthuthukisiwe obufana nokunemba kwe-CNC machining noma ukusika i-laser. Ubuchwepheshe bokukhiqiza okungeziwe njengokuncibilika kwe-laser okukhethiwe nakho kusetshenziselwa ukuthuthukisa ukunemba kwengxenye nokuphindaphinda.

Ukukhetha Izinto kanye Nokulawula Ikhwalithi
Ukukhethwa kwempahla yezihlungi ze-Q ephezulu kubalulekile. Izinto ezinokulahlekelwa okuncane nokuzinza okuphezulu ziyadingeka ukuze kuncishiswe ukulahlekelwa kwamandla nokuqinisekisa ukusebenza okuzinzile. Izinto ezivamile zihlanganisa izinsimbi ezihlanzeke kakhulu (isb., ithusi, i-aluminium) kanye nama-dielectrics alahleka kancane (isb., izitsha zobumba ze-alumina). Kodwa-ke, lezi zinto zivame ukubiza futhi kube inselele ukuzicubungula. Ukwengeza, ukulawulwa kwekhwalithi okuqinile kuyadingeka ngesikhathi sokukhethwa nokucutshungulwa kwezinto ezibonakalayo ukuze kuqinisekiswe ukuhambisana kwezakhiwo zezinto ezibonakalayo. Noma yikuphi ukungcola noma amaphutha ezintweni kungaholela ekulahlekelweni kwamandla kanye nokuncipha kwe-Q-factor.

Ukunemba Kokuhlanganisa Nokushuna
Inqubo yokuhlanganisa yeizihlungi eziphezulu ze-Qkufanele inembe kakhulu. Izingxenye zidinga ukumiswa kahle futhi zihlanganiswe ukuze kugwenywe ukungaqondani kahle noma izikhala, ezingehlisa isithunzi ukusebenza kwesihlungi. Kuzihlungi ze-high-Q eziguqulekayo, ukuhlanganiswa kwezinqubo zokushuna ne-cavity yesihlungi kubangela izinselele ezengeziwe. Isibonelo, kuzihlungi ze-dielectric resonator ezinemishini yokushuna ye-MEMS, usayizi wama-activator we-MEMS mncane kakhulu kuneresonator. Uma i-resonator nama-activator e-MEMS enziwa ngokuhlukana, inqubo yokuhlanganisa iba yinkimbinkimbi futhi ibize, futhi ukungaboni ngaso linye okuncane kungase kuthinte ukusebenza kwesihlungi.

Ukuzuza Umkhawulokudonsa Oqhubekayo kanye Nokuthunazeka
Ukudizayina isihlungi esifundekayo se-Q esiphezulu esinomkhawulokudonsa ongashintshi kuyinselele. Ukuze kugcinwe umkhawulokudonsa oqhubekayo ngesikhathi sokushuna, i-Qe elayishiwe yangaphandle kufanele ihluke ngokuqondile nemvamisa emaphakathi, kuyilapho ukuxhumanisa kwe-inter-resonator kufanele kuhluke ngokuphambene nemvamisa yesikhungo. Izihlungi eziningi eziguqulekayo ezibikwe ezincwadini zibonisa ukwehla kokusebenza nokuhluka komkhawulokudonsa. Amasu anjengokuhlangana kukagesi kanye nozibuthe asetshenziswa ukuze adizayine izihlungi ezingaguquki zomkhawulokudonsa, kodwa ukufeza lokhu ngokwenza kusalokhu kunzima. Isibonelo, isihlungi esisebenzisekayo se-TE113 semodi embaxambili ye-cavity kubikwe ukuthi sifinyelele ku-Q-factor ephezulu engu-3000 phezu kobubanzi baso bokushuna, kodwa ukuhluka komkhawulokudonsa waso kusafinyelele ku-±3.1% phakathi kwebanga elincane lokushuna.

Amaphutha Okukhiqiza Nokukhiqiza Okukhulu
Ukungapheleli kokwenziwayo okunjengomumo, usayizi, kanye nokuchezuka kwendawo kungangenisa umfutho owengeziwe kumodi, okuholela ekuhlanganeni kwemodi ezindaweni ezihlukene ku-k-space nokudalwa kwamashaneli emisebe engeziwe, ngaleyo ndlela kwehlise i-Q-factor. Kumadivayisi e-nanophotonic esikhala samahhala, indawo enkulu yokwenziwa kanye neziteshi ezilahlekelwa kakhulu ezihlotshaniswa ne-nanostructure arrays kwenza kube nzima ukufeza izici eziphezulu ze-Q. Nakuba impumelelo yokuhlolwa ibonise ama-Q-factors aphakeme ngokungu-10⁹ kuma-on-chip microresonators, ukwakhiwa kwesilinganiso esikhulu sezihlungi ze-Q ephezulu kuvame ukubiza futhi kudla isikhathi. Amasu afana ne-grayscale photolithography asetshenziselwa ukwakha izihlungi zesikali se-wafer, kodwa ukuzuza ama-Q-factors aphezulu ekukhiqizeni ngobuningi kuseyinselele.

Ukuhwebelana Phakathi Kokusebenza Nezindleko
Izihlungi ze-High-Q ngokuvamile zidinga imiklamo eyinkimbinkimbi nezinqubo zokukhiqiza ezinembayo ukuze kuzuzwe ukusebenza okuphakeme, okwandisa kakhulu izindleko zokukhiqiza. Kuzinhlelo zokusebenza ezingokoqobo, kunesidingo sokulinganisa ukusebenza kanye nezindleko. Isibonelo, ubuchwepheshe be-silicon micromachining buvumela ukwenziwa kwenqwaba yezindleko eziphansi zamaresonator aguqulekayo nezihlungi kumabhendi aphansi. Kodwa-ke, ukuzuza ama-Q-factors aphezulu kumabhendi emvamisa ephezulu kuhlala kungahlolisiswa. Ukuhlanganisa ubuchwepheshe bokushuna be-silicon RF MEMS nezindlela zokubumba umjovo ezingabizi kakhulu kunikeza isisombululo esingaba khona sokukhiqiza okuhlasimulisayo, okungabizi kakhulu kwezihlungi ze-Q ephezulu kuyilapho kugcinwa ukusebenza okuphezulu.
