Ngā whanaketanga hangarau hou oNgā photodiode horonga
Ko ngā photodiode avalanche he hangarau matua i roto i ngā optoelectronics hou, e hono ana i te āputa i waenga i ngā hangarau tuku ihongā diode whakaahuame ngā ngongo whakarea whakaahua. Ka taea e rātou te whakarato i te whiwhinga ā-roto mā te pānga horonga, kia tutuki ai te kite i te tairongo teitei me te pupuri tonu i te pakari me te kiato o ngā taputapu haurua-ira.
Te whanaketanga tonu oPūoko Whakaahua APDKo te hangarau, tae atu ki ngā whanaketanga o ngā rauemi, te hoahoa hanganga me ngā momo whakahaere, kei te whakawhānui tonu i ana mahi me te whānuitanga o te tono. Ko ngā putanga hou o ngā hua whānui whiwhi, ngā hoahoa ngaio mō ngā awhe roangaru motuhake, me ngā whakapainga o ngā āhuatanga haruru kei te pana i ngā rohe o ngā mea ka taea mō ēnei taputapu.
Ngā whanaketanga hou o te APDPūoko Whakaahuahangarau kei roto i ēnei:
Hua whānui-kaha rawa: Kua tutuki i ngā kairangahau tētahi taputapu whakaahua APD germanium/silicon me te whānui-kaha e neke atu ana i te 1 THz. I tutuki tēnei putanga nui mā te hanga tika i te tohatoha o te mara hiko me te hanga i te pānga orooro i te wā o te tukanga horonga.
2. Te kite i te matapo o te rā kua whakarei ake: Ko te hoahoa ārai kotahi-polar hou e whakaatu ana i te pikinga o te horonga hukapapa tae atu ki te 5.9 × 10^5 me te kaha kite o te 2.33 × 10^16 Jones i roto i te APD ultraviolet taumata-wafer.
3. Te whakahaere i te ngaohiko pakaru kua whakapaitia: Ko ngā tikanga hou mō te whakahaere i te ngaohiko pakaru ko te whakakotahi i tētahi ngongo mimiti horapa i hangaia i te wā kotahi me te rohe taputapu APD. Ka pana tonu ēnei whanaketanga i ngā rohe o ngā āheinga o te hangarau APD, ka tautoko i ngā tono hou me te whakarei ake i te mahi a ngā mea o nāianei.
I te ahunga whakamua o te rangahau, ka taea e tātou te tumanako ka piki ake te pai o te hangarau APD Photodetector, inā koa i ngā wāhanga pēnei i te whakaiti haruru, te whakanui ake i te whānui o te whānui, te whakarei ake i te aro me te whakawhānui i te kapinga. Mā ēnei whanaketanga ka noho tonu te APD hei wāhanga nui i roto i ngā mara kua pakeke pēnei i te whakawhitiwhiti kōrero me ngā mara hou pēnei i te hangarau irahiko, ngā pūnaha motuhake me ngā taputapu pūtaiao matatau.
