Ngā putanga hou i roto iKaiwhakarerekē LiNbO3
Nō nā tata nei, kua tukuna e ngā kairangahau Hainamana tētahi mana pupuri matua mō te hangarau raka auau taiaho PDH. He pūnaha raka auau taiaho PDH e hangai ana ki te SOA kore-raina (Semiconductor Optical Amplifier) hei whakaputa i ngā taha taha. Ko te whāinga o tēnei mana pupuri he aro ki ētahi āhuatanga matua o te pūnaha raka auau taiaho PDH (Pound-Drever-Hall) tuku iho nā te whakamahinga o te lithium niobate (LiNbO3 modulator) me ētahi atu.kaiwhakarerekē hiko-whatu.
1. Ko ngā raruraru matua o te otinga tuku iho ko:
1.1 Te utu nui me te hanganga uaua: Ko ngā whakarerekētanga hiko-whatu tuku iho e hiahia ana ki ngā ara iahiko taraiwa RF me ngā ara iahiko whakahāngai.
1.2 Te aro ki te taiao: Te aro ki ngā huringa pāmahana me te ahotea, ka ngāwari ki ngā rerekētanga āhua porowhita.
1.3 Pānga whakarerekētanga whānui toenga (RAM): Ka puta te piko DC o te tohu hapa i tēnei, ka neke haere te pūwāhi raka taiaho, ā, ka pā kino ki te pumau mō te wā roa o te pūnaha.
2. Ko te otinga auaha i whakatakotoria e te rōpū rangahau ko:
Whakarērea rawatia te whakarerekētanga hiko-whatu tuku iho, ka whakamahi i tētahi hoahoa mahi tahi owhakakaha whatu haurua-haurua(whakakaha SOA) i honoa ki ngā whakawhiti auau acousto-whatu ara-rua. Ko te kaupapa mahi motuhake ko: Whai muri i te wehewehe i te taiaho purapura, ka nekehia te auau e ngā whakawhiti auau acousto-whatu ara-rua e rua, ka puta he rerekētanga auau, kātahi ka honoa ngā ara mārama e rua ka werohia ki roto i te whakakaha SOA i te āhua kukū whiwhi. Mā te whakamahi i ngā pānga kore-raina pēnei i te whakaranu ngaru-whā (FWM) o teWhakakaha SOA, ka whakaputahia paitia ngā tohu maha-taha e hiahiatia ana mō te raka auau PDH.
3. Ka kawea mai e tēnei hangarau ngā painga mahi whakararuraru e whai ake nei:
3.1 Te wikitoria i te raruraru RAM me te whakatutuki i te pumau roa-tino-tiketike: Ka whakauruhia e te taputapu whakakaha SOA (i roto i te kete pūrerehua te nuinga) te whakahaere pāmahana, ā, he tino kore e pāngia e ngā raruraru taiao, ka karohia te raruraru RAM mai i te tikanga ā-tinana, ā, ka tutuki te tika o te raka roa o te kōhao he pai ake i te 5×10⁻¹¹/rā.
3.2 Te taurite tika o ngā whitiki taha, he whakapainga nui i te ōwehenga tohu-ki-haruru: Mā te whakahaere motuhake i te nui o te nekehanga o ngā whakawhiti auau acousto-whatu rua-ara (100 MHz – 200 MHz) e ngā oscillator e rua e whakahaerehia ana e te ngaohiko (VCO), ka taea te taurite pai i te wā auau o ngā whitiki taha kua hangaia ki te awhe hiato kore utu (FSR) o te kōhao tohutoro, ā, ka tino whakapai ake i te ōwehenga tohu-ki-haruru o te tohu hapa.
3.3 Te whakaiti i te utu me te whakapai ake i te whai huatanga, e whai hua ana ki te whakaitiiti i te pūnaha: Ki te kore te modulator hiko-whatu utu nui me ngā ara iahiko uaua, ko te kaha hiko SOA anake e hiahiatia ana e te whakakaha whatu, kia iti ake ai te pūnaha katoa, kia iti ake ai te utu, ā, kia pai ake ai mō ngā tono mara waho taiaho tino tika me te whakaitiiti.
3.4 Ko ngā tūmanako whānui mō te whakamahinga me te hiahia o te mākete mō tēnei hangarau ko:
Ngā karaka whatu mō te wāhi me te waka: Ko ōna āhuatanga ārai-whakararuraru e tino tutuki ana i ngā whakaritenga o te ao rererangi me ngā waka kore tangata.
Ngā mita taumaha kuantum me ngā mita whakawhiti ngota matao: Ka taea te whakamahi mō te tūhuratanga whenua tino tika me te whakatere i raro i te wai.
Te pūoko muka teitei me te radar huinga ā-wāhanga honohono (LiDAR): Ka taea te whakarato i ngā pūtake mārama tohutoro whānui-rārangi tino whaiti, kāore he rerenga.
I raro i te ia o te hurihanga matūriki tuarua o te ao me te whakaitiiti i ngā pūoko matūriki, kua tino piki ake te hiahia o te mākete mō ngā kōwae waeine taiaho ka taea te whakahaere motuhake, he iti te utu, he pumau hoki, ā, he tino tika te tutuki a tēnei hangarau patent i tēnei ia o te mākete.
