Cov kev tshwm sim tshiab hauvLiNbO3 modulator
Tsis ntev los no, cov kws tshawb fawb Suav tau tso tawm daim ntawv pov thawj tsim khoom tseem ceeb ntawm PDH laser zaus xauv thev naus laus zis. Lub kaw lus PDH laser zaus xauv raws li nonlinear SOA (Semiconductor Optical Amplifier) los tsim cov kab sib txuas. Daim ntawv pov thawj no lub hom phiaj yog los daws ntau qhov teeb meem tseem ceeb hauv PDH (Pound-Drever-Hall) laser zaus xauv system ib txwm muaj vim yog kev siv lithium niobate (LiNbO3 modulator) thiab lwm yamelectro-optic modulator.
1. Cov teeb meem tseem ceeb ntawm cov kev daws teeb meem ib txwm muaj xws li:
1.1 Tus nqi siab thiab cov qauv nyuaj: Cov modulators electro-optic ib txwm xav tau kev tsav tsheb RF thiab cov voj voog bias nyuaj.
1.2 Kev rhiab heev ntawm ib puag ncig: Kev rhiab heev rau qhov kub thiab txias hloov pauv, yooj yim rau qhov tsis zoo ntawm lub xeev polarization.
1.3 Qhov cuam tshuam ntawm qhov seem amplitude modulation (RAM): Qhov no ua rau DC bias ntawm lub teeb liab yuam kev, ua rau lub laser locking point tsis txav thiab cuam tshuam loj heev rau kev ruaj khov ntawm lub system mus sij hawm ntev.
2. Cov kev daws teeb meem tshiab uas pab pawg tshawb fawb tau hais yog:
Tso tseg tag nrho cov qauv hluav taws xob-optic modulator thiab txais yuav kev tsim qauv sib koom tes ntawmsemiconductor optical amplifier(SOA amplifier) ua ke nrog ob txoj kev acousto-optic zaus shifters. Lub hauv paus ntsiab lus ua haujlwm tshwj xeeb yog: Tom qab faib cov noob laser, nws yog qhov tseeb zaus-hloov los ntawm ob txoj kev dual-txoj kev acousto-optic zaus shifters, tsim kom muaj qhov sib txawv zaus, thiab tom qab ntawd ob txoj kev ntawm lub teeb tau sib xyaw ua ke thiab txhaj rau hauv SOA amplifier hauv lub xeev nce saturation. Los ntawm kev siv cov teebmeem nonlinear xws li plaub-yoj sib xyaw (FWM) ntawmSOA amplifier, cov teeb liab ntau sab uas xav tau rau PDH zaus xauv tau tsim tawm zoo.
3. Cov thev naus laus zis no coj cov txiaj ntsig zoo hauv qab no:
3.1 Kov yeej qhov teeb meem RAM thiab ua tiav qhov ruaj khov ntev ntev: Lub cuab yeej SOA amplifier (feem ntau yog hauv pob npauj npaim) sib xyaw ua ke tswj qhov kub thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig, zam qhov teeb meem RAM los ntawm lub cev thiab ua tiav qhov ntev ntawm qhov cavity locking precision zoo dua 5 × 10⁻¹¹ / hnub.
3.2 Kev sib phim meej ntawm cov sidebands, kev txhim kho tseem ceeb hauv qhov sib piv ntawm lub teeb liab thiab lub suab nrov: Los ntawm kev tswj hwm tus nqi hloov pauv ntawm ob lub dual-path acousto-optic frequency shifters (100 MHz - 200 MHz) los ntawm ob lub voltage-controlled oscillators (VCO), lub sijhawm zaus ntawm cov sidebands tsim tuaj yeem phim zoo kawg nkaus nrog qhov ntau yam dawb spectral (FSR) ntawm qhov chaw siv, yog li txhim kho qhov sib piv ntawm lub teeb liab thiab lub suab nrov ntawm lub teeb liab yuam kev.
3.3 Kev txo nqi thiab kev txhim kho kev ua haujlwm zoo, uas ua rau lub kaw lus me me: Yog tsis muaj lub tshuab hluav taws xob kim thiab cov voj voog nyuaj, SOA optical amplifier tsuas yog xav tau kev tsav tsheb tam sim no yooj yim, ua rau tag nrho lub kaw lus me dua, tus nqi qis dua, thiab tsim nyog dua rau kev siv laser sab nraud thiab kev ua kom me me.
3.4 Cov kev cia siab dav dav rau kev siv thiab kev xav tau ntawm kev ua lag luam ntawm cov thev naus laus zis no suav nrog:
Qhov chaw thiab lub tsheb optical moos: Nws cov yam ntxwv tiv thaiv kev cuam tshuam zoo kawg nkaus ua tau raws li qhov yuav tsum tau ua ntawm aerospace thiab unmanned tsheb teb.
Cov ntsuas quantum gravimeters thiab cov ntsuas atomic txias: Siv tau rau kev tshawb nrhiav geological siab thiab kev caij nkoj hauv qab dej.
Kev ntsuas fiber ntau thiab coherent phased array radar (LiDAR): Muaj peev xwm muab cov kab dav dav heev, tsis muaj kev cuam tshuam.
Nyob rau hauv qhov sib txawv ntawm qhov thib ob thoob ntiaj teb quantum revolution thiab miniaturization ntawm quantum sensors, kev thov ua lag luam rau autonomous controllable, pheej yig, thiab ruaj khov zaus-stabilized laser module modules tau nce siab heev, thiab cov thev naus laus zis patent no ua tau raws li qhov sib txawv ntawm kev ua lag luam no.
