Te kaupapa mahi o te taiaho haurua-ira

Te kaupapa mahi orēhia haurua-ira

Tuatahi, ka whakaurua ngā whakaritenga tawhā mō ngā taiaho haurua-ira, tae atu ki ēnei āhuatanga matua:
1. Mahi hikohiko: tae atu ki te ōwehenga mate, te whānui raina hihiri me ētahi atu tawhā, ka pā tika ēnei tawhā ki te mahi a ngā taiaho haurua-ira i roto i ngā pūnaha whakawhitiwhiti kōrero.
2. Ngā tawhā hanganga: pērā i te rahi me te whakaritenga o te kanapa, te whakamāramatanga o te mutunga tango, te rahi tāutanga me te rahi whakarāpopototanga.
3. Roangaru: Ko te whānuitanga roangaru o te taiaho haurua-irahiko he 650 ~ 1650nm, ā, he teitei te tika.
4. Ia paepae (Ith) me te ia whakahaere (lop): Mā ēnei tawhā ka whakatau i ngā āhuatanga tīmatanga me te āhua mahi o te taiaho haurua-ira.
5. Mana me te ngaohiko: Mā te ine i te mana, te ngaohiko me te ia o te taiaho haurua-ira e mahi ana, ka taea te tuhi i ngā kōpiko PV, PI me te IV kia mārama ai ki ō rātou āhuatanga mahi.

Te kaupapa mahi
1. Ngā tikanga whakanui: Ka whakatūria te tohatoha hurihanga o ngā kaikawe utu i roto i te reo hiko (rohe hohe). I roto i te haurua-ira, ka tohuhia te kaha o ngā irahiko e te raupapa o ngā taumata kaha tata tonu. Nō reira, me nui ake te maha o ngā irahiko i raro i te awhi kawe i te āhua kaha teitei i te maha o ngā kōhao i runga i te awhi valence i te āhua kaha iti i waenganui i ngā rohe awhi kaha e rua kia tutuki ai te hurihanga o te tau matūriki. Ka tutuki tēnei mā te whakamahi i te pānga pai ki te hononga ōrite, ki te hononga hetero rānei, me te werohanga i ngā kaikawe e tika ana ki roto i te paparanga hohe hei whakaoho i ngā irahiko mai i te awhi valence kaha iti ki te awhi kawe kaha teitei ake. Ina honoa anō te maha o ngā irahiko i roto i te āhua taupori matūriki hurihanga ki ngā kōhao, ka puta te tukunga whakaoho.
2. Hei whiwhi i te hihi whakaohooho taurite, me whāngai anō te hihi whakaohooho i roto i te resonator whatu kia maha ngā wā hei hanga i te wiri laser, ka hangaia te resonator o te laser e te mata pakaru tūturu o te karaihe semiconductor hei whakaata, he mea whakakikorua ki te pito o te mārama me te kiriata dielectric maha-papa whakaata teitei, ā, ka whakakikoruatia te mata maeneene ki te kiriata whakaata whakaiti. Mō te laser semiconductor kōhao Fp (kōhao Fabry-Perot), ka taea te hanga ngāwari i te kōhao FP mā te whakamahi i te papa pakaru tūturu poutū ki te papa hononga pn o te karaihe.
(3) Hei hanga i tētahi wiri pūmau, me kaha te reo taiaho ki te whakarato i tētahi hua nui hei utu mō te ngaronga whatu i puta mai i te resonator me te ngaronga i puta mai i te putanga taiaho mai i te mata o te kōhao, ā, me whakanui tonu i te mara mārama i roto i te kōhao. Me whai weronga iahiko kaha tēnei, arā, he nui te hurihanga tau matūriki, ko te teitei ake o te tohu o te hurihanga tau matūriki, ko te nui ake o te hua, arā, me tutuki te whakaritenga i tētahi āhuatanga paepae iahiko. Ina tae te taiaho ki te paepae, ka taea te whakaata i te mārama me tētahi roangaru motuhake i roto i te kōhao me te whakanui ake, ā, i te mutunga ka hanga he taiaho me te putanga tonu.

Te whakaritenga mahi
1. Te whānui o te whakarerekētanga me te tere: he mea nui ngā taiaho haurua-ira me tā rātou hangarau whakarerekētanga i roto i te whakawhitiwhiti kōrero whatu ahokore, ā, ka pā tika te whānui o te whakarerekētanga me te tere ki te kounga whakawhitiwhiti kōrero. Taiaho whakarerekētanga ā-roto (taiaho whakatikatika tika) he pai mō ngā momo mara rerekē o te whakawhitiwhiti muka whatu nā te mea he tere te tuku me te iti o te utu.
2. Ngā āhuatanga āwhata me ngā āhuatanga whakarerekētanga: Ngā taiaho urupare tohatoha haurua-arataki (Reera DFB) kua noho hei puna mārama nui i roto i te whakawhitiwhiti muka whatu me te whakawhitiwhiti whatu ātea nā te mea he tino pai ō rātou āhuatanga hihi me ngā āhuatanga whakarerekētanga.
3. Te utu me te hanga papatipu: Me whai ngā taiaho hiko-haurua i ngā painga o te utu iti me te hanga papatipu kia tutuki ai ngā hiahia o te hanga me ngā tono nui.
4. Te whakapaunga hiko me te pono: I roto i ngā horopaki tono pēnei i ngā pokapū raraunga, me iti te whakapaunga hiko me te pono nui ngā taiaho haurua-ira hei whakarite i te mahi pumau mo te wā roa.
