Ukuchaneka kweMishini yeCandelo
Izihluzi ze-High-Q zifuna ukuchaneka okuphezulu kakhulu ekusetyenzisweni kwee-component machining. Nokuba ukuphambuka okuncinci ngobukhulu, imo, okanye indawo kunokuchaphazela kakhulu ukusebenza kwesihluzi kunye ne-Q-factor. Umzekelo, kwii-cavity filters, ubukhulu kunye noburhabaxa bomphezulu we-cavity buchaphazela ngokuthe ngqo i-Q-factor. Ukuze kufezekiswe i-Q-factor ephezulu, ii-components kufuneka zenziwe ngomatshini ngobuchule obuphezulu, zihlala zifuna iiteknoloji zokuvelisa eziphambili ezifana noomatshini be-CNC obuchanekileyo okanye ukusika nge-laser. Iiteknoloji zokuvelisa ezongezelelweyo ezifana nokunyibilika kwe-laser ekhethiweyo nazo zisetyenziselwa ukuphucula ukuchaneka kwe-component kunye nokuphindaphinda.

Ukukhethwa kwezinto kunye noLawulo loMgangatho
Ukukhethwa kwezinto ezisetyenzisiweyo kwiifilitha ze-high-Q kubaluleke kakhulu. Izinto ezilahlekileyo nezizinzileyo kakhulu ziyafuneka ukunciphisa ukulahleka kwamandla nokuqinisekisa ukusebenza okuzinzileyo. Izinto eziqhelekileyo ziquka iintsimbi ezicocekileyo kakhulu (umz., ubhedu, i-aluminium) kunye nee-dielectrics ezilahlekileyo kancinci (umz., ii-alumina ceramics). Nangona kunjalo, ezi zinto zihlala zibiza kakhulu kwaye zinzima ukuzisebenzisa. Ukongeza, ulawulo oluqinileyo lomgangatho luyimfuneko ngexesha lokukhetha nokucubungula izinto ukuqinisekisa ukuhambelana kweempawu zezinto. Nakuphi na ukungcola okanye iziphene kwizinto ezisetyenzisiweyo kunokukhokelela ekulahlekelweni kwamandla kunye nokuncipha kwe-Q-factor.

UkuHlanganisa kunye nokuLungisa ngokuchanekileyo
Inkqubo yokuhlanganisaizihluzi ze-high-Qkufuneka zichaneke kakhulu. Izinto ezisetyenzisiweyo kufuneka zibekwe ngokuchanekileyo kwaye zidityaniswe ukuze kuthintelwe ukungalungelelani okanye izithuba, nto leyo enokonakalisa ukusebenza kwesihluzi. Kwizihluzi ze-high-Q ezilungisekayo, ukuhlanganiswa kweendlela zokulungisa kunye nomngxuma wesihluzi kubangela imingeni eyongezelelweyo. Umzekelo, kwiihluzi ze-dielectric resonator kunye neendlela zokulungisa ze-MEMS, ubungakanani bee-actuators ze-MEMS buncinci kakhulu kune-resonator. Ukuba ii-actuators ze-resonator kunye ne-MEMS zenziwe ngokwahlukeneyo, inkqubo yokuhlanganisa iba nzima kwaye ibiza kakhulu, kwaye ukungalungelelani okuncinci kunokuchaphazela ukusebenza kokuhlengahlengiswa kwesihluzi.

Ukufezekisa i-Constant Bandwidth kunye ne-Tunability
Ukuyila isihluzo esinokulungiswa okuphezulu kwe-Q esine-bandwidth engaguqukiyo kunzima. Ukuze kugcinwe i-bandwidth engaguqukiyo ngexesha lokulungiswa, i-Qe elayishiweyo yangaphandle kufuneka yahluke ngokuthe ngqo kwi-center frequency, ngelixa ii-inter-resonator couplings kufuneka zahluke ngokuphambeneyo kwi-center frequency. Uninzi lwezihluzo ezinokulungiswa ezixeliweyo kwincwadi zibonisa ukuwohloka kokusebenza kunye notshintsho lwe-bandwidth. Iindlela ezifana nee-couplings zombane kunye ne-magnetic ezilinganisiweyo zisetyenziswa ukuyila izihluzo ezinokulungiswa kwe-bandwidth engaguqukiyo, kodwa ukufezekisa oku ngokusebenzayo kusanzima. Umzekelo, isihluzo se-TE113 esinokulungiswa kabini-mode cavity sixelwe ukuba sifezekise i-Q-factor ephezulu ye-3000 kuluhlu lwayo lokulungiswa, kodwa utshintsho lwaso lwe-bandwidth lusafikelele kwi-±3.1% kuluhlu oluncinci lokulungiswa.

Iziphene zoMveliso kunye neMveliso enkulu
Iziphene zokwenza izinto ezifana nemilo, ubungakanani, kunye nokuphambuka kwesimo kunokungenisa amandla ongezelelweyo kwimo, nto leyo ekhokelela ekudibaneni kwemo kwiindawo ezahlukeneyo kwisithuba se-k kunye nokudalwa kweendlela zokukhanya ezingaphezulu, ngaloo ndlela kunciphisa i-Q-factor. Kwizixhobo ze-nanophotonic zesithuba esikhululekileyo, indawo enkulu yokwenza izinto kunye neendlela ezininzi ezilahlekileyo ezinxulumene ne-nanostructure arrays zenza kube nzima ukufezekisa ii-Q-factors eziphezulu. Ngelixa impumelelo yovavanyo ibonise ii-Q-factors eziphezulu njenge-10⁹ kwii-microresonators ezikwi-on-chip, ukwenziwa okukhulu kwee-high-Q filters kudla ngokubiza kakhulu kwaye kuthatha ixesha. Iindlela ezifana ne-grayscale photolithography zisetyenziselwa ukwenza ii-wafer-scale filter arrays, kodwa ukufezekisa ii-Q-factors eziphezulu kwimveliso yobuninzi kusaqhubeka kungumngeni.

Utshintshiselwano phakathi kokusebenza kunye neendleko
Izihluzi ze-High-Q zihlala zifuna uyilo oluntsonkothileyo kunye neenkqubo zokwenza ezichanekileyo ukuze kufezekiswe ukusebenza okuphezulu, nto leyo enyusa kakhulu iindleko zemveliso. Kwizicelo ezisebenzayo, kukho imfuneko yokulinganisela ukusebenza kunye neendleko. Umzekelo, iteknoloji ye-silicon micromachining ivumela ukwenziwa kwebhetshi engabizi kakhulu yee-resonators ezihlengahlengiswayo kunye nezihluzi kwiibhendi ze-frequency eziphantsi. Nangona kunjalo, ukufezekisa ii-Q-factors eziphezulu kwiibhendi ze-frequency eziphezulu akukahlolwa. Ukudibanisa iteknoloji yokulungisa i-silicon RF MEMS kunye neendlela zokubumba injection ezingabizi kakhulu kunika isisombululo esinokubakho sokwenza ii-filters ze-high-Q ezinokukhuliswa, ezingabizi kakhulu ngelixa kugcinwa ukusebenza okuphezulu.
