Kamuri tembiricha yakakwira sensitivity 1550 NMAvalanche Photodiode Detector

Muchiitiko chiri pedyo (SWIR) bhendi, yakanyanya sensitivity yakakwira Avalanche diodes inoshandiswa zvakanyanya mukukurukurirana kwe optoelectration uye lidar zvikumbiro. Nekudaro, iyo yazvino iri pedyo naAvalared Avalanche Photo Inalas), zvichikonzera kuderedzwa kwakakura mukunzwa kwechishandiso. Kwemakore, vazhinji vanotsvaga vanoshingairira kutsvaga zvinhu zvitsva zvemasemiconductor zvinhu zvinowirirana neIngaas platform platform

Iyo Innovativative 1550 NM Avalanche Photodiode Detector Inobatsira Kubudirira kweLidar Systems

Chikwata cheVatsvagiri muUnited Kingdom uye United States vane kekutanga nguva yakabudirira kukudziridza mutsva wekupedzisira - Sensitivity 1550 NM APD Phyitetector (Avalanche Photodetector), kubhuroka kwakavimbisa kuvandudza kwazvo kuita kweLidar masisitimu uye mamwe maOptoelectronic application.

Zvishandiso zvitsva zvinopa zvakakosha zvakanakira

Iko kusimbisa kwekutsvagisa uku ndiko kushandiswa kwekutsvaga kwezvinhu. Vaongorori vakasarudza gaassb seyakagadziriswa layer uye algaassb seyekuwanzesa. Iyi dhizaini inosiyana neyechinyakare ingaas / inp uye inounza zvakakwanisika zvakanakira:

1.gaAssb Kubata Layer: GAASEB ine iyo yekunyora yakafanana kuIngaas, uye kushandurwa kubva kuGASEBER COUNSB

2.ALGAASSB Muwandeshi Layer: Algaassb Muvergeler Layer iri yepamusoro kune yechinyakare inp uye intalas inowanza layer mukuita. Izvo zvinonyanya kuratidzwa mukuwana kwakakwirira pamhepo tembiricha, yakakwira bandwidth uye Ultra-yakaderera ruzha.

Nezvakanakisa zviratidzo zvechiratidzo

ChitsvaAPD PhotosDetector(Avalanche Photodiode Detector) zvakare inopa zvakakosha kugadzirisa mumametrics:

1. Ultra-yakakwira kuwana: iyo Ultra-yepamusoro-yakakwira yekuwana tembiricha yemakamuri, uye munguva pfupi yapfuura Dr. Jin Xiao yakawedzera kugadzirwa uye maitiro akawedzerwa kusvika kuM = 1212.

2. Ruzha rwakanyanya: runoratidza ruzha rwakawandisa (F <3, wana m = 70; f <4, wana m = 100).

3. Yakanyanya Quantum Kubudirira: Pasi pekutanga kuwana, iyo quantum yekubudirira yakakwira se 5935.3%. Yakasimba tembiricha kugadzikana: kupatsanurana kunzwa pane yakadzika tembiricha ndeyesafare 11.83 mv / k.

Zvakawanda zvinoshandiswa kushandisa

Uyu APD INPD ine zvakakosha zvizere zveLidar Systems uye mafoton zvikumbiro:

3. Kuwedzeredza kushanda zvakanaka: Inogona kushanda zvakanaka pamhepo tembiricha isina kuomesesa matinish ekutonhora, kurerutsa kutumirwa mune dzakasiyana siyana zvinoshanda.

Iko kuvandudzwa kweiyi 1550 NM Sacm Acm Acm Acm Acm Apd Photodetector Ichi chinyorwa chinotarisirwa kuwedzera kugona kweLidar masisitimu, kunyanya mune isina kuvharirwa tydar masisitimu, pamwe neyemahara-nzvimbo yekutaurirana.
