Lithium Tantalate (ltoi) Umuvuduko mwinshi wa electro-optic modulator

Lithium tantalate (ltoi) umuvuduko mwinshiModutor ya electro-optic

Ibinyabiziga byisi yose birakomeje kwiyongera, bitwarwa no kwambere kwambere mu ikoranabuhanga rishya nka 5G ndetse n'ubwenge bw'ibihimbano (AI), bitera ingorane zikomeye kubagororwa mu nzego zose za optique. By'umwihariko, igisekuru gikurikira electro-optique modulator ikoranabuhanga risaba kwiyongera kw'ibiciro byo kohereza amakuru kuri 200 mu muyoboro umwe mu gihe hagabanywa ibiciro n'ibiciro. Mu myaka mike ishize, tekinoroji ya Photonics yakoreshejwe cyane mu isoko rya Transceiver, ahanini bitewe nuko Fesics ya Silicon ishobora kuba misa ikoreshwa muburyo bwa CMO zikuze. Nyamara, soi electro-optique modulators zishingiye kuri dinderier itandukanya ibibazo bikomeye muri karwidth, kubikoresha amashanyarazi, kwinjiza imbaraga, kwinjiza nabi no kutabogama. Izindi nzira yikoranabuhanga mu nganda zirimo Impyisi, Filime ntoya niobate litiro, electro-optique polymers, hamwe nibindi byinshi-byinshi-bihuriza hamwe ibisubizo byo guhuza ibikorwa byo kwishyira hamwe. Lnoi ifatwa nkigisubizo gishobora kugera kubikorwa byiza muri ultra-umuvuduko mwinshi hamwe nububasha bwo hasi, ariko, kuri ubu, ifite ibibazo mubijyanye na misa nibiciro. Vuba aha, itsinda ryatangije filime yoroheje lithium (ltoi) ihuriro rya photosic hamwe na photerictée nini hamwe ninzeko nini ya fototelectric. Ariko, kugeza ubu, igikoresho cyibanze cyaItumanaho ryiza, ultra-umuvuduko mwinshi wa electro-optic modulator, ntabwo yagenzuwe muri ltoi.

Muri ubu bushakashatsi, abashakashatsi ba mbere bateguye modulator ya rezo ya electique, imiterere yerekana ishusho ya buri gice cya lithium.Modutor ya electro-optiquebiramenyekana. Mu rwego rwo kugabanya gutakaza inkomoko ya Microwave, abashakashatsi bo muri uyu murimo basabye bwa mbere gukoresha ifeza nk'ibikoresho byiza, kandi ifeza electrode ifite ubuzima bwiza na 82% ugereranije na zahabu yakoreshejwe na zahabu yakoreshejwe.

Igishushanyo 1 ltoi electro-optic modulator yimiterere, igishushanyo mbonera cyicyiciro, Microwave Electrode igihome cyo gutakaza.

Igishushanyo 2 yerekana ibikoresho byubushakashatsi nibisubizo bya Ltoi Electro-optic modulator yaubukana bwa moduitedGutahura bitaziguye (IMDD) muri sisitemu yo gutumanaho neza. Ubushakashatsi bwerekana ko modulator ya electro-optique irashobora kwanduza ibimenyetso bya Pam8 ku gipimo cya 176 GBD hamwe na bene yapimwe ya 3.8 × 10⁻² munsi ya 25% sd-fec. Kuri 200 GBD Bom4 na 208 GBD Pam2, Ber yari make cyane kurenza urwego rwa 15% sd-fec na 7% HD-FEC. Ijisho n'ibisubizo bya hestogramu ku gishushanyo cya 3 byerekana mu buryo bwerekana ko modulator ya electro-optique irashobora gukoreshwa muri sisitemu yo kwihuta hamwe n'umurongo muremure n'ikosa rito.

Igishushanyo Ubushakashatsi 2 ukoresheje ltoi electro-optic modulator yaUbukana bwa moduitedKumenya neza (IMDD) muri sisitemu yo gutumanaho Optique (a) igikoresho; . . .

Uyu murimo ugaragaza umuvuduko wambere ltoi electro-optic modulator hamwe na 3 db bandwidth ya 110 ghz. Muburyo bwa module igabanya ubukana bwa IMDD, igikoresho kigera ku mukoresha umwe wa 405 Gutta-s, s, igereranywa n'imikorere myiza ya postro-optique na plasma. Mu bihe biri imbere, ukoresheje byinshi bigoyeIQ ModulatorIbishushanyo cyangwa byinshi byateye imbere Ubuhanga bwo gukosora, cyangwa gukoresha igihombo cyo hasi ya microwave nka quartz scantrates, biteganijwe ko biteganijwe ko ibikoresho bya quartz bizagera ku gipimo cy'itumanaho cya 2 tbit / s cyangwa hejuru. Ihujwe nibyiza byihariye bya LTOI, nko kurwara hasi hamwe ningaruka zo gupima kubera porogaramu ya RF izatanga ikiguzi gikuru, ingufu-yihuta ya sisitemu yihuta na sisitemu ya microwave.
