Te hoahoa ara whatu o te tapawhā hāngaingā taiaho pupuhi
He tirohanga whānui mō te hoahoa ara whatu
He taiaho muka kua tāpirihia ki te thulium-whakaranu soliton whakarara rua-roa-ngaru, he mea raka-aratau-kore, e hangai ana ki te hanganga whakaata mowhiti muka kore-raina.
2. Whakaahuatanga ara whatu
Ko te soliton resonant rua-ngaru-roa kua whakapōreareahia ki te thuliummuka rēserie whakamahi ana i tētahi hoahoa hanganga kōhao "8" te āhua (Pikitia 1).
Ko te taha maui te porowhita matua kotahi-angi, ko te taha matau he hanganga whakaata porowhita muka whatu kore-raina. Kei roto i te porowhita kotahi-angi maui he wehewehe paihere, he muka whatu 2.7m kua pania ki te thulium (SM-TDF-10P130-HE), me te hononga muka whatu roopu 2 μm me te tauwehenga hononga o te 90:10. Kotahi te Isolator e whakawhirinaki ana ki te pōraritanga (PDI), e rua ngā Kaiwhakahaere Pōraritanga (ngā kaiwhakahaere Pōraritanga: PC), he muka tiaki-pōraritanga 0.41m (PMF). Ka tutuki te hanganga whakaata mowhiti muka whatu kore-raina i te taha matau mā te hono i te mārama mai i te porowhita kotahi-angi maui ki te whakaata mowhiti muka whatu kore-raina i te taha matau mā te hononga whatu hanganga 2×2 me te tauwehenga o te 90:10. Kei roto i te hanganga whakaata mowhiti muka whatu kore-raina i te taha matau he muka whatu 75-mita te roa (SMF-28e) me te kaiwhakahaere pōraritanga. Ka whakamahia he muka whatu aratau-kotahi 75-mita hei whakarei ake i te pānga kore-raina. I konei, ka whakamahia he hononga muka whatu 90:10 hei whakanui ake i te rerekētanga ā-wāhanga kore-raina i waenga i te horapa o te taha matau me te taha maui. Ko te roa katoa o tēnei hanganga roangaru-rua he 89.5 mita. I roto i tēnei whakatakotoranga whakamātautau, ka haere tuatahi te rama papu mā roto i tētahi whakakotahi hihi kia tae atu ki te muka whatu kua pania ki te thulium. Whai muri i te muka whatu kua pania ki te thulium, ka honoa he hononga 90:10 hei huri i te 90% o te pūngao ki roto i te kōhao me te tuku i te 10% o te pūngao ki waho o te kōhao. I taua wā anō, he tātari Lyot birefringent kei roto i tētahi muka whatu e pupuri ana i te pōraritanga kei waenganui i ngā kaiwhakahaere pōraritanga e rua me tētahi pōraritanga, e whai wāhi ana ki te tātari i ngā roangaru hihi.
3. Mātauranga papamuri
I tēnei wā, e rua ngā tikanga matua mō te whakanui ake i te kaha o te pā o ngā taiaho pā. Ko tētahi huarahi ko te whakaiti tika i ngā pānga kore-raina, tae atu ki te whakaheke i te kaha tihi o ngā pā mā roto i ngā tikanga maha, pērā i te whakamahi i te whakahaere marara mō ngā pā totoro, ngā oscillator nui, me ngā taiaho pā wehewehe-hihiko, me ētahi atu. Ko tētahi atu huarahi ko te rapu tikanga hou ka taea te aro atu ki te kohikohinga wāhanga kore-raina, pērā i te rite-ā-koe me ngā pā tapawhā. Ka taea e te tikanga kua whakahuatia ake nei te whakanui angitu i te kaha o te pā o tereera pāorooroki ngā tekau nanojoules. Ko te haruru soliton whakahoro (Dissipative soliton resonance: DSR) he tikanga hanga ira tapawhā i whakatakotoria tuatahitia e N. Akhmediev et al. i te tau 2008. Ko te āhuatanga o ngā pāoro haruru soliton whakahoro ko te mea, i te pupuri tonu i te kaha, ka piki haere te whānui me te kaha o te pāoro tapawhā wehewehe kore-ngaru me te pikinga o te kaha papu. Ki tētahi taumata, ka pakaru tēnei i te herenga o te ariā soliton tuku iho mō te kaha pāoro kotahi. Ka taea te whakatutuki i te haruru soliton whakahoro mā te hanga i te mimiti kua kōtui me te mimiti kua kōtui whakamuri, pērā i te pānga hurihuri pōrari kore-raina (NPR) me te pānga whakaata mowhiti muka kore-raina (NOLM). Ko te nuinga o ngā pūrongo mō te whakaputanga o ngā pāoro haruru soliton whakahoro e hangai ana ki ēnei tikanga maukati-aratau e rua.
