Ukunemba Komshini Wezingxenye
Izihlungi ze-High-Q zidinga ukunemba okuphezulu kakhulu ekusetshenzisweni kwezingxenye. Ngisho nokuphambuka okuncane ngobukhulu, ukuma, noma isikhundla kungathinta kakhulu ukusebenza kwesihlungi kanye ne-Q-factor. Isibonelo, kuzihlungi ze-cavity, ubukhulu kanye nokungaguquguquki kobuso be-cavity kuthinta ngqo i-Q-factor. Ukuze kufezwe i-Q-factor ephezulu, izingxenye kumele zenziwe ngomshini ngokunemba okuphezulu, ngokuvamile kudinga ubuchwepheshe bokukhiqiza obuthuthukisiwe njengokusebenza kwe-CNC ngokunemba noma ukusika nge-laser. Ubuchwepheshe bokukhiqiza obungeziwe njengokuncibilikisa i-laser ekhethiwe busetshenziswa futhi ukuthuthukisa ukunemba kwezingxenye kanye nokuphindaphindwa kwazo.

Ukukhethwa Kwezinto Ezibalulekile Nokulawulwa Kwekhwalithi
Ukukhethwa kwezinto zokuhlunga ze-high-Q kubalulekile. Izinto ezinokulahleka okuncane kanye nokuqina okuphezulu ziyadingeka ukuze kuncishiswe ukulahlekelwa amandla nokuqinisekisa ukusebenza okuzinzile. Izinto ezivamile zifaka phakathi izinsimbi ezihlanzekile kakhulu (isb., ithusi, i-aluminium) kanye ne-dielectrics ezilahlekelwa kancane (isb., i-alumina ceramics). Kodwa-ke, lezi zinto zivame ukubiza kakhulu futhi ziyinselele ukuzicubungula. Ngaphezu kwalokho, ukulawulwa kwekhwalithi okuqinile kuyadingeka ngesikhathi sokukhethwa kwezinto nokucubungula ukuqinisekisa ukuhambisana kwezakhiwo zezinto. Noma yikuphi ukungcola noma amaphutha ezintweni kungaholela ekulahlekelweni kwamandla kanye nokwehla kwe-Q-factor.

Ukuqonda Kokuhlanganisa Nokuhlela
Inqubo yokuhlanganisaizihlungi ze-high-Qkumele kube nembambo kakhulu. Izingxenye zidinga ukufakwa kahle futhi zihlanganiswe ukuze kugwenywe ukungalungi kahle noma izikhala, okungonakalisa ukusebenza kwesihlungi. Kuma-filter aphezulu e-Q alungisekayo, ukuhlanganiswa kwezindlela zokulungisa nomgodi wesihlungi kuletha izinselele ezengeziwe. Isibonelo, kuma-filter e-dielectric resonator anezindlela zokulungisa ze-MEMS, usayizi wama-actuator e-MEMS mncane kakhulu kune-resonator. Uma ama-actuator e-resonator nama-actuator e-MEMS enziwa ngokwehlukana, inqubo yokuhlanganisa iba yinkimbinkimbi futhi ibiza kakhulu, futhi ukungalungi okuncane kungathinta ukusebenza kokulungisiwa kwesihlungi.

Ukufinyelela i-bandwidth eqhubekayo kanye nokulungiselelwa
Ukuklama isihlungi esilungisekayo se-high-Q esine-bandwidth engaguquki kuyinselele. Ukuze kugcinwe i-bandwidth engaguquki ngesikhathi sokulungisa, i-Qe elayishiwe yangaphandle kumele ihluke ngqo ngemvamisa ephakathi, kuyilapho ama-coupling e-inter-resonator kumele ahluke ngokuphambene nemvamisa ephakathi. Iningi lezihlungi ezilungisekayo ezibikwe ezincwadini zibonisa ukuwohloka kokusebenza kanye nokwehluka kwe-bandwidth. Amasu afana nama-coupling kagesi kanye ne-magnetic alinganisiwe asetshenziswa ukuklama izihlungi ezilungisekayo ze-bandwidth engaguquki, kodwa ukufeza lokhu ngokusebenzayo kusalokhu kunzima. Isibonelo, isihlungi se-cavity se-TE113 esilungisekayo sabikwa ukuthi sifinyelele i-Q-factor ephezulu engu-3000 ngaphezu kobubanzi baso bokulungisa, kodwa ukwehluka kwaso kwe-bandwidth kusafinyelele ku-±3.1% ngaphakathi kobubanzi obuncane bokulungisa.

Amaphutha Okukhiqiza Nokukhiqizwa Okukhulu
Ukungapheleli kokwenziwa okufana nesimo, usayizi, kanye nokuphambuka kwesimo kungangenisa umfutho owengeziwe kumodi, okuholela ekuhlanganisweni kwemodi ezindaweni ezahlukene esikhaleni se-k kanye nokudalwa kweziteshi ezengeziwe zokukhanya, ngaleyo ndlela kuncishiswe i-Q-factor. Kumadivayisi e-nanophotonic esikhala esikhululekile, indawo enkulu yokwenziwa kanye neziteshi eziningi ezilahlekile ezihlotshaniswa nama-array e-nanostructure kwenza kube nzima ukufeza ama-Q-factor aphezulu. Ngenkathi impumelelo yokuhlola ibonise ama-Q-factor aphezulu njengo-10⁹ kuma-microresonator aku-on-chip, ukwenziwa okukhulu kwezihlungi ze-high-Q kuvame ukubiza futhi kuthatha isikhathi. Amasu afana ne-grayscale photolithography asetshenziselwa ukwakha ama-array e-wafer-scale filter, kodwa ukufeza ama-Q-factor aphezulu ekukhiqizweni kwesisindo kusalokhu kuyinselele.

Ukuhwebelana Phakathi Kokusebenza Nezindleko
Izihlungi ze-High-Q ngokuvamile zidinga imiklamo eyinkimbinkimbi kanye nezinqubo zokukhiqiza ezinembile kakhulu ukuze kufezwe ukusebenza okuphezulu, okwandisa kakhulu izindleko zokukhiqiza. Ezisetshenzisweni ezisebenzayo, kunesidingo sokulinganisela ukusebenza kanye nezindleko. Isibonelo, ubuchwepheshe be-silicon micromachining buvumela ukwenziwa kwe-batch eshibhile yama-resonator alungisekayo kanye nezihlungi kuma-frequency band aphansi. Kodwa-ke, ukufeza ama-Q-factor aphezulu kuma-frequency band aphezulu akukahlolwa. Ukuhlanganisa ubuchwepheshe bokuhlela be-silicon RF MEMS namasu okubumba umjovo angabizi kakhulu kunikeza ikhambi elingaba khona lokukhiqizwa kwezihlungi ze-high-Q ezingakhuliswa, ezingabizi kakhulu ngenkathi kugcinwa ukusebenza okuphezulu.
