Saj zawg zog bipolartheem modulator

Nyob rau hauv lub arena ntawm high-speed optical kev sib txuas lus thiab quantum technology, tsoos modulators tab tom ntsib kev ua tau zoo bottlenecks! Tsis txaus cov teeb liab purity, inflexible theem tswj, thiab lub zog siv zog ntau dhau - cov teeb meem no cuam tshuam kev txhim kho thev naus laus zis.

Bipolarelectro-optical theem modulatortuaj yeem ua tiav ob-theem txuas mus ntxiv ntawm theem ntawm cov teeb liab kho qhov muag. Lawv muaj kev sib koom ua ke siab, tsis tshua muaj qhov tsis zoo, kev hloov pauv siab bandwidth, qis ib nrab-yoj voltage, thiab siab puas tsuaj rau lub zog kho qhov muag. Lawv tsuas yog siv rau kho qhov muag chirp tswj nyob rau hauv high-speed optical kev sib txuas lus systems thiab entangled lub xeev tiam nyob rau hauv quantum tseem ceeb tis systems. Cov tiam ntawm sidebands nyob rau hauv ROF systems thiab txo ntawm stimulated Brillouin scattering (SBS) nyob rau hauv analog optical fiber kev sib txuas lus systems, ntawm lwm yam teb.

Covbipolar theem modulatorua tiav cov kev tswj xyuas meej ntawm cov theem ntawm cov teeb liab kho qhov muag los ntawm ob-theem txuas ntxiv theem hloov kho, thiab tshwj xeeb tshaj yog ua kom pom tus nqi tshwj xeeb hauv kev sib txuas lus kho qhov muag ceev thiab quantum tseem ceeb faib.

1. Kev sib koom ua ke siab thiab kev puas tsuaj loj: Nws txais kev tsim qauv monolithic, compact loj, thiab txhawb kev puas tsuaj rau optical zog. Nws tuaj yeem ua tau ncaj qha nrog cov khoom siv hluav taws xob muaj zog laser thiab tsim nyog rau lub sijhawm ua haujlwm zoo ntawm millimeter-wave sidebands hauv ROF (Optical Wireless) systems.

2. Chirp suppression thiab SBS tswj: Nyob rau hauv high-speed coherent kis tau tus mob, lub linearity ntawmtheem modulationtuaj yeem cuam tshuam cov chirp ntawm optical signals. Hauv kev sib txuas lus analog optical fiber ntau, los ntawm kev ua kom zoo dua qhov tob ntawm theem kev hloov kho, qhov cuam tshuam Brillouin tawg (SBS) tuaj yeem txo qis, yog li txuas ntxiv qhov sib kis.

Nyob rau hauv quantum key faib (QKD), lub xeev entangled ntawm photon khub ua hauj lwm ua "quantum key" rau kev ruaj ntseg kev sib txuas lus - qhov tseeb ntawm nws cov kev npaj ncaj qha txiav txim qhov tsis-eavesdropping khoom ntawm tus yuam sij. Qhov "yooj yim" ntawm bipolar theem modulator yog xav txog hauv nws lub peev xwm los kho cov theem tsis zoo kom hloov mus rau ib puag ncig cuam tshuam ntawm qhov sib txawv ntawm cov fiber ntau txuas (xws li kub hloov pauv thiab theem drift tshwm sim los ntawm cov neeg kho tshuab kev ntxhov siab), ua kom muaj kev ua haujlwm siab ntawm entangled photon khub. Qhov "kev ruaj ntseg" yog ua tiav los ntawm kev tswj qhov kub thiab txias thiab theem-txheej zaus thev naus laus zis, uas txwv tsis pub lub suab nrov hauv qab ntawm quantum nrov txwv thiab tiv thaiv decoherence ntawm quantum xeev thaum sib kis. Qhov ob lub ntsiab lus ntawm "kev yoog raws + kev ruaj ntseg" tsis tsuas yog txhim kho tus nqi ntawm kev sib kis luv luv hauv cheeb tsam hauv nroog network (xws li kev ua yuam kev me ntsis tsawg dua 1% nyob rau hauv 50 kilometers), tab sis kuj txhawb kev ncaj ncees ntawm cov yuam sij hauv kev sib kis mus ntev hauv kev sib txuas sib txuas (xws li tshaj li ib puas kilometers thoob plaws lub nroog), ua lub hauv paus tseem ceeb hauv lub tsev. kev sib txuas lus network.
