Component Machining Precision
Izihluzi eziphezulu ze-Q zifuna ukuchaneka okuphezulu kakhulu kumatshini wecandelo. Nokuba ukutenxa kuncinci kubungakanani, imilo, okanye indawo kunokuchaphazela kakhulu ukusebenza kwesihluzi kunye ne-Q-factor. Umzekelo, kwizihluzi zecavity, imilinganiselo kunye noburhabaxa bomphezulu bombhobho buchaphazela ngqo i-Q-factor. Ukufezekisa i-Q-factor ephezulu, amacandelo kufuneka enziwe ngoomatshini ngokuchaneka okuphezulu, ahlala efuna itekhnoloji yokuvelisa ephucukileyo efana nokuchaneka kweCNC machining okanye ukusika i-laser. Itekhnoloji eyongezelelweyo yokuvelisa efana nokunyibilika kwelaser ekhethiweyo nayo isetyenziselwa ukuphucula ukuchaneka kwecandelo kunye nokuphindaphinda.

Ukukhethwa kwezinto eziphathekayo kunye noLawulo loMgangatho
Ukukhethwa kwezinto eziphathekayo kwizihluzi eziphezulu ze-Q kubalulekile. Izinto eziphathekayo ezinokulahlekelwa okuphantsi kunye nokuzinza okuphezulu zifunekayo ukunciphisa ukulahlekelwa kwamandla kunye nokuqinisekisa ukusebenza okuzinzile. Izinto eziqhelekileyo ziquka iintsimbi ezicocekileyo (umzekelo, ubhedu, i-aluminiyam) kunye nelahleko ephantsi ye-dielectrics (umzekelo, iiseramikhi zealumina). Nangona kunjalo, ezi zixhobo zihlala zibiza kakhulu kwaye kunzima ukuzilungisa. Ukongezelela, ulawulo olungqongqo lwekhwalithi luyimfuneko ngexesha lokukhethwa kwezinto kunye nokucubungula ukuqinisekisa ukuhambelana kwiipropati eziphathekayo. Nakuphi na ukungcola okanye iziphene kwizinto eziphathekayo kunokukhokelela ekulahlekelweni kwamandla kunye nokunciphisa i-Q-factor.

INdibano kunye nokuTyunwa kokuChaneka
Inkqubo yendibano yeizihluzi eziphezulu ze-Qkufuneka ichaneke kakhulu. Amalungu kufuneka abekwe ngokuchanekileyo kwaye adityaniswe ukuthintela ukungahambi kakuhle okanye izithuba, ezinokuthi zithobe ukusebenza kwesihluzi. Kwizihluzi eziphezulu ze-Q eziguqulekayo, ukudityaniswa kweendlela zokulungisa kunye ne-cavity yokucoca kubangela imingeni eyongezelelweyo. Ngokomzekelo, kwiifilitha ze-dielectric resonator kunye neendlela zokulungisa i-MEMS, ubungakanani bee-activators ze-MEMS buncinci kakhulu kune-resonator. Ukuba i-resonator kunye ne-MEMS actuator zenziwe ngokwahlukeneyo, inkqubo yokuhlanganisa iba nzima kwaye ixabisa kakhulu, kwaye ukulungelelaniswa okuncinci kunokuchaphazela ukusebenza kokucoca.

Ukufezekisa iBandwidth rhoqo kunye nokuQebeleka
Ukuyila i-high-Q enokuguqulelwa isihluzi esine-bandwidth eqhubekayo ngumngeni. Ukugcina i-bandwidth eqhubekayo ngexesha lokulungiswa, i-Qe elayishiwe yangaphandle kufuneka ihluke ngokuthe ngqo kunye ne-frequency center, ngelixa i-inter-resonator couplings kufuneka ihluke ngokungafaniyo kunye ne-frequency center. Uninzi lwezihluzi eziguqulekayo ezichazwe kuncwadi zibonisa ukuthotywa kokusebenza kunye nokwahluka kobubanzi bomda. Ubuchwephesha obufana nokudityaniswa kombane kunye nemagnethi zisetyenzisiwe ukuyila izihluzi eziguquguqukayo ze-bandwidth, kodwa ukufezekisa oku ekusebenzeni kuhlala kunzima. Umzekelo, i-TE113 enokutyibilikayo yokucoca imowudi yemowudi ephindwe kabini yaxelwa ukuba ifikelele kwi-Q-factor ephezulu ye-3000 ngaphezulu koluhlu lwayo lokulungisa, kodwa ukuhluka kwayo kwebhanwidth kusafike ku ± 3.1% ngaphakathi koluhlu oluncinci lokulungisa.

Iziphene zokuVelisa kunye neMveliso eNkulu
Ukungafezeki kokwenziwa okufana nokumila, ubungakanani, kunye nokuphambuka kwesikhundla kunokwazisa umfutho owongezelelweyo kwimowudi, ekhokelela ekudibaneni kwemowudi kwiindawo ezahlukeneyo kwi-k-space kunye nokudalwa kweziteshi ezongezelelweyo ze-radiative, ngaloo ndlela ukunciphisa i-Q-factor. Kwizixhobo ze-nanophotonic ze-free-space, indawo enkulu yokuvelisa kunye nemijelo elahlekileyo ehambelana ne-nanostructure arrays yenza kube nzima ukufezekisa izinto eziphezulu ze-Q. Ngelixa impumelelo yovavanyo ibonise ii-Q-factors ziphezulu njenge-10⁹ kwi-on-chip microresonators, ukwenziwa komgangatho omkhulu wezihluzi ze-Q zihlala zibiza kwaye zidla ixesha. Ubuchwephesha obufana ne-grayscale photolithography isetyenziselwa ukwenza uluhlu lwesihluzi se-wafer-scale, kodwa ukufumana izinto eziphezulu ze-Q kwimveliso yobuninzi kuhlala kungumngeni.

Urhwebo phakathi kokuSebenza kunye neNdleko
Izihluzi eziphezulu ze-Q zifuna ukuyila okunzima kunye neenkqubo ezichanekileyo zokuvelisa ukuphumeza ukusebenza okuphezulu, okwandisa kakhulu iindleko zemveliso. Kwizicelo eziphathekayo, kukho imfuneko yokulinganisa ukusebenza kunye neendleko. Umzekelo, itekhnoloji ye-silicon micromachining ivumela ukwenziwa kwebhetshi ephantsi kwexabiso eliphantsi kweeresonators ezinokutya kunye nezihluzi kwiibhendi ezisezantsi. Nangona kunjalo, ukufezekisa izinto eziphezulu ze-Q kwiibhendi eziphezulu zefrikhwensi kuhlala kungahlolisiswa. Ukudibanisa i-silicon RF MEMS itekhnoloji yokulungisa kunye neendlela zokubumba iinaliti ezingabizi kakhulu zibonelela ngesisombululo esinokubakho sokwenziwa kwe-scalable, ngexabiso eliphantsi lokwenziwa kwezihluzi eziphezulu ze-Q ngelixa kugcinwa ukusebenza okuphezulu.
