He papa epitaxial GaAs laser 4 inihi 6 inihi VCSEL poutū tukunga mata o te kōhao roangaru laser 940nm hononga kotahi
Ko ngā āhuatanga matua o te pepa epitaxial taiaho GaAs ko
1. Hanganga hononga-kotahi: Ko tēnei taiaho he mea tito i te nuinga o te wā mai i tētahi puna matū kotahi, ka taea te whakarato i te tukunga mārama whai hua.
2. Roangaru: Nā te roangaru o te 940 nm ka uru ki te awhe hihi pūwhero, he pai mō ngā momo tono.
3. Teitei o te whai huatanga: Ki te whakatauritea ki ētahi atu momo taiaho, he teitei te whai huatanga o te tahuritanga hiko-whatu o VCSEL.
4. Kiato: He iti te mōkihi VCSEL, ā, he ngāwari ki te whakauru.
5. He iti te paepae o te au hiko me te tino pai o te mahi: Ko ngā taiaho heterostructure kua tanumia he tino iti te taumata o te iahiko o te au hiko (hei tauira, 4mA/cm²) me te tino pai o te rerekētanga o waho (hei tauira, 36%), me te mana putanga raina neke atu i te 15mW.
6. Te pumau o te aratau arataki ngaru: Ko te painga o te taiaho heterostructure tanumia ko te pumau o te aratau arataki ngaru nā te mea he tikanga arataki ngaru e arahina ana e te taupū whakaata me te whānui whaiti o te rīpene hohe (tata ki te 2μm).
7. He tino pai te whai huatanga o te hurihanga hiko-whakaahua: Mā te arotau i te tukanga tipu epitaxial, ka taea te whiwhi i te whai huatanga matū ā-roto me te whai huatanga hurihanga hiko-whakaahua hei whakaiti i te ngaronga ā-roto.
8. Te pono me te ora: ka taea e te hangarau tipu epitaxial kounga teitei te whakarite i ngā pepa epitaxial me te āhua mata pai me te iti o te koha, ka whakapai ake i te pono me te ora o te hua.
9. He pai mō ngā momo tono: He whānuitia te whakamahinga o te rau epitaxial diode taiaho GAAS i roto i te whakawhitiwhiti muka whatu, ngā tono ahumahi, ngā pūwero whero me ngā pūoko whakaahua me ētahi atu mara.
Ko ngā huarahi tono matua o te pepa epitaxial taiaho GaAs ko
1. Te whakawhitiwhiti kōrero whatu me te whakawhitiwhiti raraunga: E whakamahia whānuitia ana ngā anga epitaxial GaAs i roto i te ao whakawhitiwhiti kōrero whatu, inā koa i roto i ngā pūnaha whakawhitiwhiti kōrero whatu tere-tiketike, mō te hanga taputapu hiko-whakaata pēnei i ngā taiaho me ngā pūoko.
2. Ngā tono ahumahi: He mea nui anō hoki ngā whakamahinga o ngā rau epitaxial taiaho GaAs i roto i ngā tono ahumahi, pērā i te tukatuka taiaho, te ine me te pūoko.
3. Ngā hikohiko kaihoko: I roto i ngā hikohiko kaihoko, ka whakamahia ngā anga epitaxial GaAs hei hanga VCsels (ngā taiaho whakaputa mata kōhao poutū), e whakamahia whānuitia ana i roto i ngā waea atamai me ētahi atu hikohiko kaihoko.
4. Ngā tono Rf: He nui ngā painga o ngā rauemi GaAs i roto i te mara RF, ā, e whakamahia ana hei hanga i ngā taputapu RF mahi-teitei.
5. Ngā taiaho ira kuantum: E whakamahia whānuitia ana ngā taiaho ira kuantum e hangai ana ki te GAAS i roto i ngā mahi whakawhitiwhiti kōrero, hauora me te ope taua, inā koa i roto i te roopu whakawhitiwhiti kōrero whatu 1.31µm.
6. Pātene Q kore mahi: Ka whakamahia te ngongo GaAs mō ngā taiaho totoka papu-diode me te pātene Q kore mahi, he mea e tika ana mō te miihini-iti, te whāwhā me te pokanga-iti.
E whakaatu ana ēnei tono i te pūmanawa o ngā anga epitaxial taiaho GaAs i roto i te whānuitanga o ngā tono hangarau-tiketike.
Kei a XKH ngā papa epitaxial GaAs me ngā hanganga me ngā matotoru rerekē kua whakaritea ki ngā hiahia o te kiritaki, e kapi ana i te whānuitanga o ngā tono pēnei i te VCSEL/HCSEL, WLAN, ngā teihana turanga 4G/5G, me ētahi atu. Ka hangaia ngā hua a XKH mā te whakamahi i ngā taputapu MOCVD matatau hei whakarite i te mahi teitei me te pono. Mō ngā mahi kawe raraunga, he whānui ā mātou hongere pūtake o te ao, ka taea te whakahaere ngāwari i te maha o ngā ota, ā, ka whakarato ratonga uara tāpiri pēnei i te whakaitiiti, te wehewehe, me ētahi atu. Mā ngā tukanga tuku whai hua ka whakarite i te tukunga i te wā tika, ā, ka tutuki hoki i ngā hiahia o te kiritaki mō te kounga me ngā wā tuku.
