Component Machining Precision
High-Q lim yuav tsum tsis tshua muaj siab precision hauv Cheebtsam machining. Txawm tias qhov sib txawv me me ntawm qhov loj me, cov duab, lossis txoj haujlwm tuaj yeem cuam tshuam rau cov lim dej ua haujlwm thiab Q-factor. Piv txwv li, nyob rau hauv kab noj hniav lim, qhov ntev thiab nto roughness ntawm kab noj hniav ncaj qha cuam tshuam rau Q-factor. Yuav kom ua tiav qhov Q-factor siab, cov khoom yuav tsum tau ua nrog kev ua haujlwm siab, feem ntau xav tau cov cuab yeej tsim khoom xws li precision CNC machining lossis laser txiav. Additive manufacturing technologies xws li xaiv laser melting kuj yog siv los txhim kho cov khoom precision thiab repeatability.

Kev xaiv khoom thiab kev tswj xyuas zoo
Kev xaiv cov khoom siv rau high-Q lim yog qhov tseem ceeb. Cov ntaub ntawv uas tsis muaj kev poob qis thiab kev ruaj ntseg siab yuav tsum tau ua kom txo qis zog thiab ua kom ruaj khov. Cov ntaub ntawv muaj xws li cov hlau purity siab (piv txwv li, tooj liab, txhuas) thiab cov khoom siv hluav taws xob tsawg (xws li alumina ceramics). Txawm li cas los xij, cov ntaub ntawv no feem ntau kim thiab nyuaj rau kev ua haujlwm. Tsis tas li ntawd, kev tswj xyuas nruj yog tsim nyog thaum xaiv cov khoom siv thiab ua kom ntseeg tau tias muaj kev sib xws hauv cov khoom siv. Txhua yam impurities lossis tsis xws luag hauv cov ntaub ntawv tuaj yeem ua rau lub zog poob thiab txo Q-factor.

Sib dhos thiab Tuning Precision
Kev sib dhos txheej txheem rauhigh-Q limyuav tsum yog qhov tseeb heev. Cov Cheebtsam yuav tsum tau muab tso rau hauv qhov tseeb thiab sib sau ua ke kom tsis txhob muaj qhov tsis zoo lossis qhov khoob, uas tuaj yeem ua rau lub lim dej ua haujlwm tsis zoo. Rau tunable high-Q cov ntxaij lim dej, kev sib koom ua ke ntawm kev kho cov txheej txheem nrog cov kab noj hniav lim ua rau muaj teeb meem ntxiv. Piv txwv li, nyob rau hauv dielectric resonator lim nrog MEMS tuning mechanisms, qhov luaj li cas ntawm MEMS actuators yog ntau me dua li resonator. Yog hais tias lub resonator thiab MEMS actuators yog fabricated nyias, cov txheej txheem los ua ke yuav complex thiab kim, thiab me ntsis misalignments yuav cuam tshuam rau lub lim tuning kev ua tau zoo.

Ua tiav qhov Bandwidth tas li thiab Tunability
Tsim kom muaj lub siab-Q tunable lim nrog qhov bandwidth tas li yog qhov nyuaj. Yuav kom tswj tau qhov bandwidth tsis tu ncua thaum lub sij hawm tu, sab nraud loaded Qe yuav tsum sib txawv ncaj qha nrog rau qhov chaw zaus, thaum inter-resonator couplings yuav tsum sib txawv inversely nrog qhov chaw zaus. Feem ntau cov tunable lim tau tshaj tawm hauv cov ntaub ntawv nthuav tawm kev ua haujlwm tsis zoo thiab kev hloov pauv bandwidth. Cov txuj ci xws li cov hluav taws xob sib npaug thiab sib nqus sib nqus tau ua haujlwm los tsim cov lim bandwidth tunable tas li, tab sis ua tiav qhov no hauv kev xyaum tseem nyuaj. Piv txwv li, lub tunable TE113 dual-mode kab noj hniav lim tau tshaj tawm kom ua tiav Q-factor siab ntawm 3000 dhau nws qhov kev sib tw, tab sis nws qhov kev hloov pauv bandwidth tseem mus txog ± 3.1% nyob rau hauv ib qho me me tuning ntau.

Manufacturing Defects thiab Loj-Scale Production
Fabrication imperfections xws li cov duab, qhov loj me, thiab qhov sib txawv ntawm qhov chaw tuaj yeem qhia lub zog ntxiv rau hom, ua rau cov qauv sib txuas ntawm cov ntsiab lus sib txawv hauv k-chaw thiab tsim cov kab hluav taws xob ntxiv, yog li txo qis Q-factor. Rau qhov chaw pub dawb nanophotonic cov khoom siv, qhov chaw tsim khoom loj dua thiab ntau qhov kev poob qis uas cuam tshuam nrog nanostructure arrays ua rau nws nyuaj rau kev ua tiav Q-factors siab. Thaum cov kev sim ua tiav tau pom tias Q-factors siab li 10⁹ hauv on-chip microresonators, loj-scale fabrication ntawm high-Q lim feem ntau kim thiab siv sij hawm. Cov txuj ci zoo li greyscale photolithography yog siv los tsim cov wafer-scale lim arrays, tab sis ua tiav qib Q-yam hauv kev tsim khoom loj tseem yog qhov nyuaj.

Kev lag luam tawm ntawm Kev Ua Haujlwm thiab Tus Nqi
High-Q cov ntxaij lim dej feem ntau xav tau cov qauv tsim thiab cov txheej txheem ua haujlwm siab kom ua tiav qhov kev ua tau zoo, uas ua rau nce nqi ntau lawm. Hauv kev siv tswv yim, yuav tsum muaj kev sib npaug ntawm kev ua haujlwm thiab tus nqi. Piv txwv li, silicon micromachining thev naus laus zis tso cai rau cov nqi qis ntawm cov khoom siv tunable resonators thiab cov ntxaij lim dej ntawm cov zaus qis. Txawm li cas los xij, kev ua tiav qib siab Q-qhov tseem ceeb hauv ntau zaus bands tseem tsis tau tshawb nrhiav. Kev sib koom ua ke ntawm silicon RF MEMS tuning thev naus laus zis nrog cov txiaj ntsig zoo txhaj tshuaj molding cov tswv yim muaj peev xwm ua kom muaj peev xwm ua tau zoo, raug nqi qis ntawm high-Q lim thaum tswj kev ua haujlwm siab.
