He kaupapa o te angiangi auau whatu i runga iMZM modulator

Ka taea te whakamahi i te marara o nga whatukuhu hei liDARpuna maramaki te tuku me te matawai i nga huarahi rereke, ka taea hoki te whakamahi hei puna rama-maha-roa o 800G FR4, ka whakakore i te hanganga MUX. I te nuinga o te wa, he iti te mana o te puna marama-maha-roa, he kore pai ranei te takai, a he maha nga raru. He maha nga painga o te kaupapa i whakauruhia mai i tenei ra, ka taea te korero mo te tohutoro. Ko te hoahoa hangahanga e whakaatuhia ana e whai ake nei: Ko te mana teiteiDFB taiahoKo te puna marama he marama CW i roto i te rohe wa me te roangaru kotahi i te auau. I muri i te paahitanga akaiwhakaraupapame te fRF auau whakarerekētanga, ka hangaia te riipene taha, a ko te waahi taha taha ko te fRF auau whakarereke. Ka whakamahia e te kaiwhakaraupapa he LNOI modulator me te 8.2mm te roa, penei i te Whakaahua b. I muri i te waahanga roa o te mana teiteiwhakahurihuri wahanga, he fRF hoki te auau whakarereke, a, me hanga e tona wahanga te tihi, te waka ranei o te tohu RF me te patere marama e hono ana tetahi ki tetahi, ka puta he tangi nui, ka nui ake nga niho whatu. Ko te rītaha DC me te hōhonutanga whakarerekētanga o te kaitahuri ka pa ki te papatahi o te marara o nga whatukuhu.

I runga i te pangarau, ko te tohu i muri i te waahi marama e whakarereketia ana e te modulator ko:
Ka taea te kite ko te waahanga o te waahanga whakaputa ko te marara o nga whatukuhu me te waahi o te waa o te wrf, a ko te kaha o te niho marara o nga whatukuhu e pa ana ki te mana o te DFB. Ma te whakatairite i te kaha o te marama e haere ana i roto i te MZM modulator mePM waahanga modulator, katahi ko te FFT, ka whiwhi te tuāwhiorangi marara auau whatu. Ko te ahua e whai ake nei e whakaatu ana i te hononga tika i waenga i te papatahi auau whatu me te rītaha DC modulator me te hōhonutanga whakarerekētanga i runga i tenei whaihanga.

Ko te ahua e whai ake nei e whakaatu ana i te hoahoa momotuhanga me te MZM bias DC o te 0.6π me te hohonutanga whakarereke o te 0.4π, e whakaatu ana ko tona papatahi he <5dB.

E whai ake nei ko te hoahoa mokihi o te MZM modulator, he 500nm te matotoru o LN, he 260nm te hohonu o te tarai, me te whanui ngaru he 1.5um. Ko te matotoru o te hiko koura he 1.2um. Ko te matotoru o te whakakikorua o runga SIO2 he 2um.

E whai ake nei te awhiowhio o te OFC i whakamatauria, me te 13 nga niho whatu koretake me te papatahi <2.4dB. Ko te auau whakarerekētanga he 5GHz, ko te RF te uta mana i roto i te MZM me te PM he 11.24 dBm me te 24.96dBm. Ka taea te whakanui ake i te maha o nga niho o te whakakorikori whakamararatanga orotika ma te whakanui ake i te mana PM-RF, a ka taea te whakanui ake i te waahi marara o nga whatu ma te whakanui ake i te huringa whakarereke. pikitia
Ko nga korero i runga ake nei i runga i te kaupapa LNOI, a ko nga mea e whai ake nei i runga i te kaupapa IIIV. Ko te hoahoa hanganga e whai ake nei: Ko te maramara te whakauru i te laser DBR, te MZM modulator, te PM phase modulator, te SOA me te SSC. Ka taea e te maramara kotahi te whakatutuki i te mahi kikokore auau whatu.

Ko te SMSR o te laser DBR he 35dB, ko te whanui raina ko te 38MHz, ko te awhe tuning he 9nm.

Ka whakamahia te MZM modulator ki te whakaputa i te taha taha me te roa o te 1mm me te bandwidth o te 7GHz@3dB anake. Ko te nuinga o te wa e whakawhäitihia ana e te impedance mismatch, whatu ngaronga ake ki te 20dB@-8B rītaha

Ko te roa o te SOA ko te 500µm, ka whakamahia hei utu i te ngaronga rereke rereke o te mata, a ko te whanui whanui he 62nm@3dB@90mA. Ko te SSC whakauru i te putanga ka pai ake te pai o te honohono o te maramara (ko te pai o te hono ko te 5dB). Ko te mana whakaputa whakamutunga he −7dBm.

Hei whakaputa i te whakamaarama o te mata, ko te 2.6GHz te RF i whakamahia, ko te mana ko 24.7dBm, ko te Vpi o te waahanga whakarereke he 5V. Ko te ahua i raro nei ko te tuāwhiorangi photophobic kua puta me te 17 niho photophobic @10dB me te SNSR teitei ake i te 30dB.

Ko te kaupapa te kaupapa mo te tuku ngaruiti 5G, a ko te ahua e whai ake nei ko te waahanga hihinga ka kitea e te kaitahuri rama, ka taea te whakaputa tohu 26G ma te 10 nga wa te auau. Kare i korerotia i konei.

Hei whakarāpopototanga, ko te auau whatu i hangaia e tenei tikanga he waahi auau, he iti te haruru o te wahanga, he mana nui me te ngawari te whakauru, engari he maha ano nga raru. Ko te tohu RF e utaina ana i runga i te PM e hiahia ana kia nui te mana, he nui te kaha o te kohi hiko, a ko te waahi auau e whakawhäitihia ana e te reiti whakarereke, tae atu ki te 50GHz, e hiahia ana kia nui ake te wa roangaru (te nuinga> 10nm) i roto i te punaha FR8. He iti te whakamahinga, kaore ano kia ranea te mana o te mana.
