Chikamu Machining Precision
Yepamusoro-Q mafirita anoda yakanyanya kurongeka mukugadzira chikamu. Kunyangwe kutsauka kudiki muhukuru, chimiro, kana chinzvimbo kunogona kukanganisa zvakanyanya kuita kwesefa uye Q-factor. Semuyenzaniso, mumafirita emhango, ukuru uye kushata kwepamusoro kwegomba kunobata zvakananga iyo Q-factor. Kuti uwane yakakwira Q-chinhu, zvikamu zvinofanirwa kugadzirwa zvine hunyanzvi hwepamusoro, kazhinji zvinoda matekinoroji ekugadzira epamberi senge chaiyo CNC machining kana laser yekucheka. Yekuwedzera yekugadzira matekinoroji senge yakasarudzika laser kunyungudika inoshandiswawo kuvandudza chikamu chaicho uye kudzokorora.

Kusarudzwa kwezvinhu uye Kudzora Kwemhando
Kusarudzwa kwezvinhu zvepamusoro-Q mafirita kwakakosha. Zvishandiso zvine kurasikirwa kwakaderera uye kugadzikana kwepamusoro kunodiwa kuderedza kurasikirwa kwesimba uye kuve nechokwadi chekuita kwakagadzikana. Zvishandiso zvakajairika zvinosanganisira simbi dzakachena (semuenzaniso, mhangura, aruminiyamu) uye yakaderera-kurasikirwa dielectrics (semuenzaniso, alumina ceramics). Zvisinei, zvinhu izvi zvinowanzodhura uye zvinonetsa kugadzirisa. Pamusoro pezvo, kusimba kwemhando yekudzora kunodiwa panguva yekusarudzwa kwezvinhu uye kugadzirisa kuti ive nechokwadi chekuenderana mune zvezvinhu zvinhu. Chero tsvina kana kukanganisa mune zvigadzirwa zvinogona kutungamirira mukurasikirwa kwesimba uye kuderedza Q-factor.

Gungano uye Tuning Precision
The assembly process forhigh-Q filtersinofanira kuva yakanyatsojeka. Zvikamu zvinofanirwa kuiswa nemazvo uye kuunganidzwa kuti zvidzivise kusarongeka kana mikaha, izvo zvinogona kukanganisa kuita kwesefa. Kune anokwenenzverwa akakwira-Q mafirita, kubatanidzwa kwetuning masisitimu nesefa cavity kunopa mamwe matambudziko. Semuenzaniso, mune dielectric resonator mafirita ane MEMS tuning michina, saizi yeMEMS actuators idiki zvakanyanya pane resonator. Kana iyo resonator neMEMS actuators ikagadzirwa zvakasiyana, maitiro egungano anove akaomarara uye anodhura, uye kushoma misalignments kunogona kukanganisa kuita kwesefa.

Kuwana Constant Bandwidth uye Tunability
Kugadzira yakakwira-Q inotakurika sefa ine inogara bandwidth kunonetsa. Kuti uchengetedze bhanwidth nguva dzose panguva yekugadzirisa, iyo yekunze yakatakura Qe inofanira kusiyanisa zvakananga nechepakati frequency, nepo inter-resonator couplings inofanira kusiyanisa zvakasiyana nepakati frequency. Mazhinji mafirita anokwenenzverwa anoshumwa mumabhuku anoratidza kuderedzwa kwekuita uye kusiyanisa kwebandwidth. Matekinoroji akadai seakaenzana magetsi uye magineti couplings anoshandiswa kugadzira anogara ari bandwidth tunable mafirita, asi kuita izvi mukuita kunoramba kwakaoma. Semuenzaniso, inoturika TE113 dual-mode cavity sefa yakanzi inowana yakakwira Q-factor ye3000 pamusoro peiyo tuning renji, asi kusiyana kwayo kwebandwidth ichiri kusvika ± 3.1% mukati mediki tuning renji.

Manufacturing Defects uye Makuru-Scale Production
Kusakwana kwekugadzira senge chimiro, saizi, uye kutsauka kwenzvimbo kunogona kuunza imwe nhanho kune modhi, zvichitungamira kumodhi yekubatanidza panzvimbo dzakasiyana mu k-nzvimbo uye kugadzirwa kweimwe nzira yemagetsi, nekudaro ichidzikisa iyo Q-factor. Kune yemahara-nzvimbo nanophotonic zvishandiso, iyo yakakura yekugadzira nzvimbo uye yakawanda yakarasika chiteshi inobatanidza nanostructure arrays inoita kuti zviome kuwana yakakwira Q-zvinhu. Kunyange zvazvo kubudirira kwekuedza kwakaratidza Q-zvinhu zvakakwirira se 10⁹ mu-chip microresonators, kugadzirwa kwakakura kwemasefa epamusoro-Q kunowanzodhura uye kunopedza nguva. Matekinoroji akaita segreyscale photolithography anoshandiswa kugadzira wafer-scale mafirita arrays, asi kuwana yakakwirira Q-zvinhu mukugadzirwa kwehuwandu kunoramba kwakaoma.

Kutengeserana Pakati Pekuita uye Mutengo
Mafirita epamusoro-Q anowanzoda dhizaini yakaoma uye yakakwirira-chaiyo magadzirirwo ekugadzira kuti awane mashandiro epamusoro, ayo anowedzera zvakanyanya mutengo wekugadzira. Mumashandisirwo anoshanda, panodiwa kuenzanisa kuita uye mutengo. Semuyenzaniso, silicon micromachining tekinoroji inobvumira yakaderera-mutengo batch kugadzirwa kwe tunable resonators uye mafirita pazasi frequency mabhendi. Nekudaro, kuwana yakakwira Q-zvinhu mumabhendi epamusoro mabhendi anoramba asina kuongororwa. Kubatanidza silicon RF MEMS tuning tekinoroji ine inodhura-inoshanda jekiseni yekuumba matekiniki inopa mhinduro inogona scalable, yakaderera-mutengo wekugadzira yepamusoro-Q mafirita uchichengetedza kushanda kwepamusoro.
