Isha iftiinka hirarka badan ee xaashida fidsan

Dhererka hirarka badanil iftiin lehon xaashi fidsan

Chips indhaha waa dariiqa lama huraanka ah si ay u sii wadaan sharciga Moore ee, waxa uu noqday is-afgaradka tacliinta iyo warshadaha, waxa ay si wax ku ool ah u xalin kartaa xawaaraha iyo dhibaatooyinka isticmaalka awoodda ay la kulmaan chips elektaroonik ah, waxaa la filayaa in ay afgembiso mustaqbalka xisaabinta caqliga leh iyo ultra-xawaaraha sare.isgaarsiinta indhaha. Sanadihii la soo dhaafay, horumar teknooloji oo muhiim ah oo ku saabsan sawir-qaadista silikoon-ku-saleysan waxay diiradda saaraysaa horumarinta shanlooyinka soo noqnoqda ee heerka microcavity soliton indhaha, kaas oo dhalin kara shanlooyinka soo noqnoqda ee isku midka ah iyada oo loo marayo microcavities indhaha. Sababtoo ah faa'iidooyinka ay u leedahay isdhexgalka sare, spectrum ballaaran iyo soo noqnoqoshada sare ee soo noqnoqoshada, heerka chip microcavity soliton light il wuxuu leeyahay codsiyada suurtagalka ah ee isgaarsiinta awoodda weyn, spectroscopy,sawir qaade microwave, cabbirka saxda ah iyo meelaha kale. Guud ahaan, wax ku oolnimada beddelidda microcavity hal soliton shanlada soo noqnoqda indhaha ayaa inta badan xaddidaysa cabbirrada la xidhiidha daloodhka indhaha. Marka la eego awoodda bamka gaarka ah, awoodda wax-soo-saarka ee shanlada soo noqnoqda ee soliton indhaha ayaa inta badan xaddidan. Soo bandhigida nidaamka cod-weyneysiinta indhaha ee dibadda waxay si lama-huraan ah u saameyn doontaa saamiga-is-beddelka dhawaaqa. Sidaa darteed, muuqaalka muuqaalka fidsan ee mikrocavity soliton shanlada soo noqnoqda indhaha ayaa noqotay raadinta goobtan.

Dhawaan, koox cilmi-baaris ah oo ku sugan Singapore ayaa horumar muhiim ah ka sameeyay goobta ilaha iftiinka mowjadaha badan ee xaashida fidsan. Kooxda cilmi-baadhistu waxay soo saareen jajab yar yar oo indhaha ah oo leh fidsan, muuqaal ballaadhan oo u dhow kala firdhinta eber, waxayna si hufan u baakadeeyeen chip-ka indhaha oo leh cidhifyo (khasaarid isku xidhan oo ka yar 1 dB). Iyada oo ku saleysan chip microcavity indhaha, saamaynta kulaylka-optical adag ee microcavity indhaha waxaa ka adkaaday nidaamka farsamo ee bamgareynta double, iyo isha iftiinka multi-wavelength leh wax soo saarka spectral siman waa la xaqiiqsaday. Iyada oo loo marayo nidaamka xakamaynta jawaab-celinta, nidaamka isha-mawjadaha-mawjadaha badan ee soliton wuxuu u shaqayn karaa si deggan wax ka badan 8 saacadood.

Wax soo saarka muuqaalka ee isha iftiinka waa qiyaastii trapezoidal, celceliska soo noqnoqda wuxuu ku saabsan yahay 190 GHz, xajmiga fidsan wuxuu daboolayaa 1470-1670 nm, flatness waxay ku saabsan tahay 2.2 dBm (is weecasho heerka caadiga ah), iyo kala duwanaansho siman oo siman ayaa ku jira 70% oo dhan kala duwanaansho muuqaal ah, oo daboolaya guutada S+C+L+U. Natiijooyinka cilmi-baarista waxaa loo isticmaali karaa isku xirnaanta indhaha ee awoodda sare leh iyo cabbir sareindhahahababka xisaabinta. Tusaale ahaan, nidaamka bandhigga isgaarsiinta awoodda-weyn ee ku salaysan isha shanlada soliton ee microcavity, kooxda shanlada inta jeer ee leh farqiga tamarta weyn ayaa wajahaya dhibaatada SNR hoose, halka isha soliton ee leh wax soo saarka muuqaal siman ay si wax ku ool ah uga gudbi karto dhibaatadan waxayna gacan ka geysaneysaa hagaajinta SNR marka la barbar dhigo habaynta macluumaadka indhaha, kaas oo leh muhiimada injineernimada.

Shaqada, oo cinwaankeedu yahay "Flat soliton microcomb source," ayaa loo daabacay sidii warqadda daboolka ee Sayniska Opto-Electronic iyada oo qayb ka ah arrinta "Digital iyo Intelligent Optics".
