He kaupapa mō te whakaitiiti i te auau whatu i runga iKaiwhakarerekētanga MZM

Ka taea te whakamahi i te marara auau whatu hei liDARpūtake māramahei tuku me te matawai i ngā ahunga rerekē i te wā kotahi, ā, ka taea hoki te whakamahi hei pūtake mārama maha-ngaru o te 800G FR4, ka whakakore i te hanganga MUX. I te nuinga o te wā, he iti te mana o te pūtake mārama maha-ngaru, kāore rānei i te pai te takai, ā, he maha ngā raruraru. He maha ngā painga o te kaupapa i whakaurua mai i tēnei rā, ā, ka taea te tirotiro hei tohutoro. Ko tana hoahoa hanganga e whakaaturia ana penei: Ko te mana-teiteiReera DFBKo te pūtake mārama he mārama CW i te rohe wā me te roangaru kotahi i te auau. I muri i te haere i roto i tekaiwhakarerekēme te auau whakarerekētanga fRF, ka whakaputaina te taha taha, ā, ko te wā taha taha ko te auau whakarerekētanga fRF. Ka whakamahia e te whakarerekētanga he whakarerekētanga LNOI me te roa o te 8.2mm, e whakaaturia ana i te Pikitia b. Whai muri i te wāhanga roa o te mana-teiteikaiwhakarerekētanga wāhanga, ko te auau whakarerekētanga he fRF anō hoki, ā, me hanga e tōna wāhanga te tihi, te raro rānei o te tohu RF me te pā o te mārama ki a rātou anō, ka hua ake he tangi nui, ka hua ake he niho whatu. Ka pā te piko DC me te hohonu o te whakarerekētanga o te whakarerekētanga ki te papatahi o te mararatanga auau whatu.

I roto i te pāngarau, ko te tohu i muri i te whakarerekētanga o te mara mārama e te kaiwhakarerekētanga ko:
Ka kitea ko te mara whatu putanga he marara auau whatu me te wā auau o te wrf, ā, ko te kaha o te niho marara auau whatu e pā ana ki te mana whatu DFB. Mā te whakatauira i te kaha o te mārama e haere ana i roto i te MZM modulator mePūwhakarerekētanga wāhanga PM, kātahi ka whiwhihia te whānuitanga marara auau whatu mā te FFT. E whakaatu ana te pikitia e whai ake nei i te whanaungatanga tika i waenga i te papatahi o te auau whatu me te taha DC o te modulator me te hohonutanga o te modulation i runga i tēnei whakatauira.

E whakaatu ana te pikitia e whai ake nei i te hoahoa hihinga whakaata me te MZM bias DC o te 0.6π me te hohonutanga whakarerekētanga o te 0.4π, e whakaatu ana ko tōna papatahi he <5dB.

Koinei te hoahoa mōkihi o te MZM modulator, he 500nm te matotoru o te LN, he 260nm te hohonutanga o te whakairo, ā, he 1.5um te whānui o te arataki ngaru. Ko te matotoru o te irahiko koura he 1.2um. Ko te matotoru o te paparanga o runga o te SIO2 he 2um.

Koinei te whānuitanga o te OFC i whakamatautauria, me te 13 ngā niho whatu-kore, ā, he papatahi te rahi, he <2.4dB. Ko te auau whakarerekētanga he 5GHz, ā, ko te kawenga mana RF 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 ngā niho o te whakaoho auau whatu mā te whakanui ake i te mana PM-RF, ā, ka taea te whakanui ake i te wā whakarerekētanga auau whatu mā te whakanui ake i te auau whakarerekētanga. pikitia
Ko te kaupapa o runga ake nei e hangai ana ki te kaupapa LNOI, ā, ko te kaupapa e whai ake nei e hangai ana ki te kaupapa IIIV. Ko te hoahoa hanganga penei: Ka whakauruhia e te maramara te taiaho DBR, te kaiwhakatikatika MZM, te kaiwhakatikatika wāhanga PM, te SOA me te SSC. Ka taea e te maramara kotahi te whakatutuki i te whakaitiiti auau whatu mahi teitei.

Ko te SMSR o te taiaho DBR he 35dB, ko te whānui o te rārangi he 38MHz, ā, ko te awhe whakarārangi he 9nm.

Ka whakamahia te MZM modulator hei whakaputa i te taha taha he 1mm te roa, ā, he 7GHz@3dB anake te whānui. Ko te nuinga o te wā ka whakawhāitihia e te kore ōrite o te aukati, te ngaronga whatu tae atu ki te 20dB@-8B te pānga.

Ko te roa o te SOA he 500µm, e whakamahia ana hei utu mō te ngaronga rerekētanga whatu whakarerekētanga, ā, ko te whānui o te whānuitanga o te hihi he 62nm@3dB@90mA. Mā te SSC whakauru i te putanga ka whakapai ake i te pai o te hononga o te maramara (ko te pai o te hononga he 5dB). Ko te mana putanga whakamutunga he tata ki te −7dBm.

Hei whakaputa i te marara auau whatu, ko te auau whakarerekētanga RF e whakamahia ana ko 2.6GHz, ko te mana ko 24.7dBm, ā, ko te Vpi o te whakarerekētanga ā-wāhanga ko 5V. Ko te ahua i raro nei ko te whānuitanga whakaahua-kore e hua mai ana me ngā niho whakaahua-kore e 17 @10dB me te SNSR teitei ake i te 30dB.

Ko te kaupapa nei he mea hanga mō te tuku ngaruiti 5G, ā, ko te ahua e whai ake nei ko te wāhanga whānuitanga i kitea e te pūoko mārama, ka taea te whakaputa i ngā tohu 26G mā te 10 ngā wā o te auau. Kāore i te whakahuatia i konei.

Hei whakarāpopototanga, ko te auau whatu i hangaia e tēnei tikanga he auau pumau, he haruru iti, he kaha teitei, ā, he ngāwari te whakauru, engari he maha anō ngā raruraru. Ko te tohu RF e utaina ana ki te PM me nui te kaha, me nui te whakamahinga hiko, ā, ko te auau e whakawhāitihia ana e te tere whakarerekētanga, tae atu ki te 50GHz, e hiahia ana kia nui ake te roanga ngaru (te nuinga o te wā >10nm) i roto i te pūnaha FR8. He iti te whakamahinga, kāore tonu i te rawaka te papatahi o te mana.
