Whakaahuatanga Hua
I tenei wa, e toru te nuinga o nga tikanga whakakore i te horonga mo InGaAs APDs: te pehi haahi, te aukati hohe me te kitenga kuaha. Ka piki ake te wa mate o nga photodiodes o te avalanche me te tino whakaiti i te reeti tatau morahi o te kairapu, i te mea he uaua rawa te pehi hohe na te mea he uaua rawa te ara iahiko pehi me te riima tohu ka kaha ki te tuku. Kei te whakamahia te aratau rapu kuaha i tenei wa i te rapunga whakaahua-kotahi. Ko te tino whakamahia nuitia.
Ka taea e te hangarau rapu whakaahua kotahi te whakapai ake i te tika me te whaihua o te punaha. I roto i te punaha korero laser mokowhiti, he tino ngoikore te kaha o te mara marama maiki, tata ki te taumata photon. Ko te tohu ka kitea e te kaitirotiro whakaahua whanui ka whakararuraru, ka rukuhia ranei e te haruru i tenei wa, i te wa e whakamahia ana te hangarau rapu whakaahua kotahi ki te Ine i tenei tohu marama tino ngoikore. Ko te hangarau rapu-whakaahua kotahi i hangai i runga i nga keeti InGaAs avalanche photodiodes ko nga ahuatanga o te iti o te tuuponotanga o muri-pupuhi, te iti o te waa me te reeti tatau teitei.
He nui te mahi a te laser rangi i roto i te maha o nga mara penei i te whakahaere ahumahi, te hoia mamao me te mokowhiti korero mokowhiti na ona ahuatanga tika me te tere, me te haere tonu o te hangarau optoelectronic. I roto i a raatau, hei taapiri atu ki te hangarau o te puihi tuku iho, kei te tukuna tonu etahi otinga kopae hou, penei i te hangarau rapu whakaahua kotahi i runga i te punaha tatau photon, e pai ake ai te kitea o te tohu whakaahua kotahi me te pehi i te haruru ki te whakapai ake. te punaha. kopae tika. I roto i te rangi-whakaahua kotahi, ka whakatauhia e te jitter te wa o te kaitirotiro whakaahua-kotahi me te whanui pulse laser te tika o te punaha rangi. I nga tau tata nei, kua tere te whanake o nga lasers picosecond mana nui, no reira ko te wa jitter o nga kaitirotiro whakaahua-tahi kua waiho hei raru nui e pa ana ki te tika o te whakatau o nga punaha rangi-whakaahua kotahi.
