Ukuthuthukiswa nokusebenzisa imojula yokupholisa ye-thermoelectric, imojula ye-TEC, i-peltier cooler emkhakheni we-optoelectronics

Thermoelectric Cooler, thermoelectric module,peltier module (TEC) idlala indima ebalulekile emkhakheni wemikhiqizo ye-optoelectronic ngezinzuzo zayo eziyingqayizivele. Okulandelayo ukuhlaziya ukusetshenziswa kwayo okubanzi emikhiqizweni ye-optoelectronic:

I. Izinkambu Zokusebenza Eziwumongo kanye Nendlela Yesenzo

1. Ukulawula izinga lokushisa okunembile kwe-laser

• Izidingo ezibalulekile: Wonke ama-lasemiconductor lasers (LDS), imithombo yephampu ye-fiber laser, namakristalu e-laser yesimo esiqinile azwela kakhulu izinga lokushisa. Ukushintsha kwezinga lokushisa kungaholela kulokhu:

• I-Wavelength drift: Ithinta ukunemba kwe-wavelength yokuxhumana (njengamasistimu e-DWDM) noma ukuzinza kokucutshungulwa kwezinto.

• Ukushintshashintsha kwamandla okukhiphayo: Kwehlisa ukuvumelana kokuphuma kwesistimu.

• Ukuhluka kwamanje kwe-Threshold: Kwehlisa ukusebenza kahle futhi kwenyusa ukusetshenziswa kwamandla.

• Ukuphila okufushane: Amazinga okushisa aphezulu asheshisa ukuguga kwamadivayisi.

• Imojula ye-TEC, umsebenzi wemojula ye-thermoelectric: Ngesistimu yokulawula izinga lokushisa elivaliwe (inzwa yokushisa + isilawuli + i-TEC module, i-TE cooler), izinga lokushisa elisebenzayo le-laser chip noma imojula lizinza endaweni efanelekile (ngokuvamile i-25 ° C± 0.1 ° C noma ukunemba okuphakeme nakakhulu), iqinisekisa ukuzinza kwe-wavelength, ukuphuma kwamandla okunwetshwa njalo, ubude besikhathi sokuphila nobukhulu. Lesi yisiqiniseko esiyisisekelo sezinkambu ezifana nokuxhumana okubonakalayo, ukucutshungulwa kwelaser, namalaser ezokwelapha.

2. Ukupholisa ama-photodetectors/ama-infrared detectors

• Izidingo ezibalulekile:

• Yehlisa ubumnyama bamanje: I-Infrared focal plane array (IRFPA) efana nama-photodiodes (ikakhulukazi i-InGaAs detectors esetshenziswa ekuxhumaneni okuseduze ne-infrared), i-avalanche photodiodes (APD), ne-mercury cadmium telluride (HgCdTe) inamaza amnyama amakhulu ngokuqhathaniswa kuthempelesha yegumbi, ehlisa kakhulu ukutholwa kwesiginali nomsindo (SNR).

• Ukucindezelwa komsindo oshisayo: Umsindo oshisayo womtshina ngokwawo uyisici esiyinhloko esikhawulela umkhawulo wokutholwa (njengamasiginali okukhanya abuthaka kanye nesithombe sebanga elide).

• Imoduli yokupholisa i-Thermoelectric, umsebenzi wemoduli yePeltier (isici se-peltier): Pholisa i-chip yomtshina noma iphakheji yonke kumazinga okushisa angaphansi kwe-ambient (afana -40°C noma ngaphansi ngisho nangaphansi). Yehlisa kakhulu umsindo wamanje omnyama nomsindo oshisayo, futhi uthuthukise kakhulu ukuzwela, izinga lokutholwa kanye nekhwalithi yesithombe yedivayisi. Kubaluleke kakhulu ezithombeni ezishisayo ze-infrared ezisebenza kahle kakhulu, amathuluzi okubona ebusuku, ama-spectrometer, kanye nezitholi zokuxhumana ze-quantum single-photon.

3. Ukulawulwa kwezinga lokushisa kwamasistimu okukhanya okunemba kanye nezingxenye

Ukushintsha kwezinga lokushisa kungabangela izinguquko kubude bendlela yokubona, ukukhukhuleka kobude obugxilile, nokushintshwa kwe-wavelength phakathi nendawo yesihlungi, okuholela ekuwohlokeni kokusebenza kwesistimu (okufana nesithombe esifiphele, indlela yokubona enganembile, namaphutha okulinganisa).

• Imojula ye-TEC, Umsebenzi wemojula yokupholisa i-thermoelectric:

• Ukulawulwa kwezinga lokushisa okusebenzayo: Izingxenye eziyinhloko ze-optical zifakwa endaweni engaphansi ye-thermal conductivity substrate, futhi imojuli ye-TEC(i-peltier cooler, idivayisi ye-peltier), idivayisi kagesi we-thermoelectric ilawula ngokunembile izinga lokushisa (ukugcina izinga lokushisa elingashintshi noma ijika elithile lokushisa).

• I-homogenization yezinga lokushisa: Susa ukuhluka kwezinga lokushisa ngaphakathi kwempahla noma phakathi kwezingxenye ukuze uqinisekise ukuzinza kokushisa kwesistimu.

• Ukumelana nokuguquguquka kwemvelo: Ukunxephezela umthelela wokushintsha kwezinga lokushisa kwemvelo kwangaphandle endleleni yokubona enembile yangaphakathi. Isetshenziswa kabanzi kuma-spectrometer anembe kakhulu, izibonakude zezinkanyezi, imishini ye-photolithography, ama-microscopes asezingeni eliphezulu, amasistimu enzwa we-fiber optical, njll.

4. Ukuthuthukiswa kokusebenza kanye nokwandiswa kwesikhathi sokuphila kwamaledi

• Izidingo ezibalulekile: Amaledi anamandla aphezulu (ikakhulukazi ukuze abonise, ukukhanya, kanye nokwelapha kwe-UV) akhiqiza ukushisa okukhulu phakathi nokusebenza. Ukwenyuka kwezinga lokushisa lokuhlangana kuzoholela kulokhu:

• Ukuncipha kokusebenza kahle kokukhanya: Ukusebenza kahle kokuguqulwa kwe-electro-optical kuncishisiwe.

• Ukushintsha kwe-Wavelength: Kuthinta ukufana kombala (njengokuboniswa kwe-RGB).

• Ukwehliswa okubukhali kobude besikhathi sokuphila: Izinga lokushisa le-Junction liyisici esibaluleke kakhulu esithinta isikhathi sokuphila samaledi (kulandelwa imodeli ye-Arrhenius).

• Amamojula e-TEC, ama-cooler e-thermoelectric, amamojula kagesi we-thermoelectric Umsebenzi: Kuzinhlelo zokusebenza ze-LED ezinamandla amakhulu kakhulu noma izimfuneko eziqinile zokulawula izinga lokushisa (njengemithombo ethile yokukhanya yokuqagela kanye nemithombo yokukhanya yezinga lesayensi), imojula ye-thermoelectric, imojula yokupholisa ye-thermoelectric, idivayisi ye-peltier, isici se-peltier singanikeza amandla okupholisa anamandla futhi anembile asebenzayo kunobubanzi obujwayelekile bokushisa, indawo yokushisa ye-LED kanye nokugcina izinga lokushisa eliphakeme. ukuphuma kokukhanya, i-spectrum ezinzile nempilo ende kakhulu.

Ii. Incazelo Eningiliziwe Yezinzuzo Ezingenakubuyiseleka zamamojula we-TEC amamojula we-thermoelectric amadivaysi e-thermoelectric (ama-peltier cooler) ku-Opto electronic Applications

1. Amandla anembile okulawula izinga lokushisa: Ingakwazi ukufinyelela ukulawulwa kwezinga lokushisa okuzinzile ngo-±0.01°C noma ngisho nokunemba okuphezulu kakhulu, okudlula kude izindlela zokuqeda ukushisa okungenzi lutho noma okusebenzayo njengokupholisa komoya nokupholisa uketshezi, ihlangabezana nezidingo eziqinile zokulawula izinga lokushisa zamadivayisi we-optoelectronic.
