Igishushanyo cya optique yinshyi kunanuka ishingiyeMZM modulator

Ikwirakwizwa rya optique rishobora gukoreshwa nka liDARisoko yumucyogusohora icyarimwe gusikana no gusikana mubyerekezo bitandukanye, kandi birashobora no gukoreshwa nkumucyo mwinshi wumucyo wa 800G FR4, ukuraho imiterere ya MUX.Mubisanzwe, urumuri rwinshi rwumucyo isoko yaba imbaraga nke cyangwa ntizipakiwe neza, kandi hariho ibibazo byinshi.Gahunda yatangijwe uyumunsi ifite ibyiza byinshi kandi irashobora koherezwa kubisobanuro.Igishushanyo cyacyo cyerekanwe kuburyo bukurikira: Imbaraga-zo hejuruLaserInkomoko yumucyo ni CW urumuri mugihe cyagenwe nuburebure bumwe bwumurongo.Nyuma yo kunyura amodulatorhamwe na modulisiyo runaka ya fRF, umurongo wo kuruhande uzabyara, kandi intera yo kuruhande ni modulisiyo ya moderi ya fRF.Modulator ikoresha moderi ya LNOI ifite uburebure bwa 8.2mm, nkuko bigaragara ku gishushanyo b.Nyuma yicyiciro kirekire-imbaraga-nyinshiicyiciro, modulisiyo yinshuro nayo ni fRF, kandi icyiciro cyayo gikeneye gukora igikonjo cyangwa inkono yikimenyetso cya RF hamwe nimpanuka yumucyo ugereranije nundi, bikavamo urusaku runini, bikavamo amenyo menshi ya optique.Kubogama kwa DC hamwe no guhindura uburebure bwa modulator birashobora kugira ingaruka kumurongo wa optique ya optique.

Imibare, ikimenyetso nyuma yumucyo uhindurwa na modulator ni:
Birashobora kugaragara ko ibisohoka optique yumurima ari optique ya optique ikwirakwizwa hamwe nintera yinshyi ya wrf, kandi ubukana bwinyo ya optique yo gukwirakwiza amenyo bifitanye isano nimbaraga za optique ya DFB.Mugereranya ubukana bwurumuri runyura muri MZM modulator naModeri yicyiciro cya PM, hanyuma FFT, optique ya frequency dispersion sprifike irabonetse.Igishushanyo gikurikira cyerekana isano itaziguye hagati ya optique yumurongo wa tekinike na modulator DC kubogama hamwe nuburebure bwimbitse bushingiye kuri iyi simulation.

Igishushanyo gikurikira cyerekana igishushanyo mbonera cyagereranijwe hamwe na MZM bias DC ya 0.6π hamwe nubujyakuzimu bwa 0.4π, byerekana ko uburinganire bwayo ari <5dB.

Ibikurikira nigishushanyo mbonera cya moderi ya MZM, LN ifite uburebure bwa 500nm, ubujyakuzimu bwa 260nm, n'ubugari bwa waveguide ni 1.5um.Ubunini bwa electrode ya zahabu ni 1.2um.Ubunini bwimyambaro yo hejuru SIO2 ni 2um.

Ibikurikira nuburyo bwa OFC yapimwe, hamwe namenyo 13 adakunze kuboneka no kuringaniza <2.4dB.Inshuro ya modulation ni 5GHz, naho ingufu za RF zipakurura MZM na PM ni 11.24 dBm na 24.96dBm.Umubare w'amenyo ya optique yumurongo wo gukwirakwiza urashobora kwiyongera mugukomeza kongera ingufu za PM-RF, kandi intera ya optique ikwirakwiza intera irashobora kwiyongera mukongera inshuro.ishusho
Ibyavuzwe haruguru bishingiye kuri gahunda ya LNOI, naho ibikurikira bishingiye kuri gahunda ya IIIV.Igishushanyo mbonera nuburyo bukurikira: Chip ihuza laser ya DBR, moderi ya MZM, moderi ya PM icyiciro, SOA na SSC.Chip imwe irashobora kugera kumikorere yo hejuru optique yinshyi.

SMSR ya laser ya DBR ni 35dB, ubugari bwumurongo ni 38MHz, naho intera yo guhuza ni 9nm.

Moderi ya MZM ikoreshwa mukubyara uruhande rufite uburebure bwa 1mm nubunini bwa 7GHz @ 3dB gusa.Ahanini bigarukira kubudahuza, gutakaza optique kugeza 20dB @ -8B kubogama

Uburebure bwa SOA ni 500µm, bukoreshwa mukwishyura modulasiyo ya optique itandukanijwe, naho umurongo wa ecran ni 62nm @ 3dB @ 90mA.SSC ihuriweho hamwe nibisohoka bitezimbere guhuza chip (gukora neza ni 5dB).Imbaraga zanyuma zisohoka ni −7dBm.

Kugirango habeho gukwirakwiza optique ya optique, inshuro ya RF modulation ikoreshwa ni 2.6GHz, ingufu ni 24.7dBm, na Vpi ya moderi ya moderi ni 5V.Igishushanyo gikurikira nigisubizo cya Photophobic spekure ifite amenyo 17 ya Photophobic @ 10dB na SNSR hejuru ya 30dB.

Gahunda igenewe kwanduza microwave ya 5G, kandi igishushanyo gikurikira nikintu cyerekana ibintu byerekana ibimenyetso byerekana urumuri, rushobora kubyara ibimenyetso 26G inshuro 10 inshuro.Ntabwo bivuzwe hano.

Muri make, optique ya optique yakozwe nubu buryo ifite intera ihamye, urusaku ruke, urusaku rwinshi hamwe no guhuza byoroshye, ariko hariho ibibazo byinshi.Ikimenyetso cya RF cyuzuye kuri PM gisaba ingufu nini, gukoresha ingufu nyinshi ugereranije, kandi intera yumurongo igarukira ku gipimo cyo guhindura, kugeza kuri 50GHz, bisaba intera nini y’umuraba (muri rusange> 10nm) muri sisitemu ya FR8.Gukoresha bike, imbaraga zingana ntizihagije.
