Kufambira mberi kwetekinoroji kwazvino kweMafotodiodhi eAvalanche
Maphotodiode eAvalanche anomiririra tekinoroji huru mu optoelectronics yemazuva ano, achivhara musiyano uripo pakati pema "echinyakare"mafotodiodhiuye machubhu e photomultiplier. Anogona kupa purofiti yemukati kuburikidza nemhedzisiro yeavalanche, nokudaro achiwana mukana wekuona zvakanyanya uku achichengetedza kusimba uye kupfupika kwemidziyo ye semiconductor.
Kuenderera mberi kwekuvandudzwa kweChinoongorora Mufananidzo cheAPDtekinoroji, kusanganisira kufambira mberi muzvinhu, dhizaini yemaumbirwo uye nzira dzekushanda, yagara ichiwedzera mabasa ayo uye huwandu hwemashandisirwo ayo. Kubudirira kwazvino muzvigadzirwa zvegain bandwidth, magadzirirwo ehunyanzvi emhando dzakasiyana dzewavelength, uye kuvandudzwa kwemaitiro eruzha kuri kusundira miganhu yekukwanisika kwemidziyo iyi.
Kufambira mberi kwazvino muAPDChinoongorora mufananidzotekinoroji inosanganisira:
Chigadzirwa chebandwidth yekuwedzera simba: Vaongorori vakawana germanium/silicon APD Photodetector ine bandwidth yekuwedzera simba inodarika 1 THz. Kubudirira uku kwakawanikwa nekugadzira magadzirirwo chaiwo ekugoverwa kwemagetsi uye kugadzira resonance effect panguva yekudonha kwemvura.
2. Kuonekwa kwakawedzerwa kwechiedza chisingaonekwe nezuva: Dhizaini itsva yekudzivirira ganda kubva kupombi imwe chete inoratidza kuwedzera kweavalanche kusvika ku5.9 × 10^5 uye kugona kuona kwe2.33 × 10^16 Jones muwafer-level ultraviolet APD.
3. Kudzora voltage yekupwanyika kwakavandudzwa: Nzira itsva dzekudzora voltage yekupwanyika dzinosanganisira kusanganisa chinopinda mumhepo chinogadzirwa panguva imwe chete nenzvimbo yemidziyo yeAPD. Kufambira mberi uku kunogara kuchisundira miganhu yemikana yetekinoroji yeAPD, zvichitsigira mashandisirwo matsva uye kusimudzira mashandiro earipo.
Nekufambira mberi kwekutsvaga, tinogona kutarisira kuwedzera kuvandudzwa kwetekinoroji yeAPD Photodetector, kunyanya munzvimbo dzakadai sekuderedza ruzha, kuwedzera bandwidth, kuwedzera kwekunzwisisa uye kuwedzera kufukidzwa. Izvi zvicharamba zvichiita kuti APD ive chinhu chakakosha muminda yakakura senge kutaurirana nefoni neminda iri kubuda senge quantum technology, masisitimu anozvitonga uye zvishandiso zvesainzi zvepamusoro.
