He rangahau hou mō te tino kikokorePūoko whakaahua InGaAs
Nā te whanaketanga o te hangarau whakaahua infrared ngaru-poto (SWIR) kua nui ngā painga ki ngā pūnaha tirohanga pō, te tirotiro ahumahi, te rangahau pūtaiao, me te tiaki haumarutanga me ētahi atu mara. I te pikinga ake o te hiahia mō te kimi i tua atu i te whānuitanga mārama e kitea ana, kei te piki haere tonu hoki te whanaketanga o ngā pūoko whakaahua infrared ngaru-poto. Heoi anō, ko te whakatutuki i te taumira teitei me te haruru itipūoko whakaahua whānuiHe maha tonu ngā wero hangarau e pā ana ki ngā hoahoa tuku iho. Ahakoa ka taea e te taputapu whakaahua-ira-pōkākā InGaAs tuku iho te whakaatu i te pai o te huringa hiko me te nekenekehanga kawe, he rerekētanga nui kei waenganui i ā rātou tohu mahi matua me te hanganga taputapu. Hei whiwhi i te pai o te matūriki (QE) teitei ake, me whai paparanga mimiti (AL) o te 3 maikiromita, neke atu rānei, ngā hoahoa tuku iho, ā, ka puta he maha ngā raruraru mai i tēnei hoahoa hanganga.
Hei whakaiti i te matotoru o te paparanga mimiti (TAL) i roto i te pūngao pōkākā poto InGaAspūoko whakaahua, he mea tino nui te whakamāmā i te whakahekenga o te mimiti i ngā roangaru roa, inā koa ka kore e ranea te mimiti i te whānuitanga roangaru roa nā te matotoru o te paparanga mimiti rohe-iti. E whakaatu ana te Pikitia 1a i te tikanga whakamāmā i te matotoru o te paparanga mimiti rohe-iti mā te whakaroa i te ara mimiti whatu. Ka whakarei ake tēnei rangahau i te pai o te matūriki (QE) i roto i te roopu pūwhero-poto mā te whakauru i tētahi hanganga aratau ārahi TiOx/Au (GMR) i te taha muri o te taputapu.
Ki te whakatauritea ki ngā hanganga whakaata whakarewa papatahi tuku iho, ka taea e te hanganga auoro aratau ārahi te whakaputa i ngā pānga mimiti auoro maha, ka tino whakarei ake i te whai huatanga mimiti o te mārama roa-ngaru. I arotauhia e ngā kairangahau te hoahoa tawhā matua o te hanganga auoro aratau ārahi, tae atu ki te wā, te hanganga rauemi, me te tauwehenga whakakī, mā te tikanga tātari ngaru hono pakari (RCWA). Nō reira, kei te pupuri tonu tēnei taputapu i te mimiti whai hua i roto i te roopu infrared ngaru-poto. Mā te whakamahi i ngā painga o ngā rauemi InGaAs, i tūhuratia hoki e ngā kairangahau te urupare ā-ira i runga i te hanganga papa. Ko te hekenga o te matotoru o te paparanga mimiti me haere tahi me te hekenga o te EQE.
Hei whakamutunga, i angitu te whakawhanaketanga o tēnei rangahau i tētahi taputapu kite InGaAs me te matotoru o te 0.98 maikiromita anake, he nui atu i te 2.5 ngā wā angiangi atu i te hanganga tuku iho. I taua wā anō, ka mau tonu te whai huatanga matūriki neke atu i te 70% i roto i te awhe roangaru 400-1700 nm. Ko te whakatutukitanga hou o te taputapu kite whakaahua InGaAs tino angiangi e whakarato ana i tētahi ara hangarau hou mō te whanaketanga o ngā pūoko whakaahua whānui-taumira teitei, iti-haruru. Ko te wā kawe kawe tere i kawea mai e te hoahoa hanganga tino angiangi e tumanakohia ana ka whakaiti nui i te whakawhitiwhiti hiko me te whakapai ake i ngā āhuatanga urupare o te taputapu. I taua wā anō, he pai ake te hanganga taputapu kua whakaitihia mō te hangarau whakauru toru-ahu kotahi-maramara (M3D), e whakatakoto ana i te turanga mō te whakatutuki i ngā rarangi pika kiato teitei.
