Intuthuko yakamuva yezobuchwephesheAma-photodiode e-Avalanche
Ama-photodiode e-Avalanche amelela ubuchwepheshe obubalulekile kuma-optoelectronics esimanje, evala igebe phakathi kwe-ama-photodiodekanye namashubhu e-photomultiplier. Anganikeza inzuzo yangaphakathi ngomphumela we-avalanche, ngaleyo ndlela afinyelele ekutholakaleni kokuzwela okuphezulu ngenkathi egcina ukuqina kanye nokuqina kwamadivayisi e-semiconductor.
Intuthuko eqhubekayo yeI-APD Photodetectorubuchwepheshe, okuhlanganisa intuthuko ezintweni zokwakha, ukwakheka kwesakhiwo kanye nezindlela zokusebenza, bulokhu bukhulisa imisebenzi yalo kanye nobubanzi bokusetshenziswa. Intuthuko yakamuva emikhiqizweni ye-gain bandwidth, imiklamo yobungcweti yebanga elithile lamaza obubanzi, kanye nokuthuthukiswa kwezici zomsindo kucindezela imingcele yamathuba ala madivayisi.
Intuthuko yakamuva ku-APDIsitholi sezithombeubuchwepheshe buhlanganisa:
Umkhiqizo we-bandwidth yokwanda okuphezulu kakhulu: Abacwaningi bathole i-germanium/silicon APD Photodetector ene-bandwidth yokwanda edlula i-1 THz. Lokhu kuthuthuka kufezwe ngokwakha ngokunembile ukusatshalaliswa kwensimu kagesi kanye nobunjiniyela bomphumela we-resonance ngesikhathi senqubo ye-avalanche.
2. Ukutholwa okuthuthukisiwe kokungaboni kwelanga: Umklamo omusha womgoqo we-unipolar ubonisa ukwanda kwe-avalanche okuphula irekhodi okufika ku-5.9 × 10^5 kanye nekhono lokutholwa elingu-2.33 × 10^16 Jones ku-ultraviolet APD esezingeni le-wafer.
3. Ukulawulwa kwe-voltage yokuqhekeka okuthuthukisiwe: Izindlela ezintsha zokulawula i-voltage yokuqhekeka zifaka phakathi ukuhlanganisa i-absorber yokusabalala eyakhiwe ngesikhathi esisodwa nesifunda sedivayisi ye-APD. Lokhu kuthuthuka kuhlala kusunduza imingcele yamathuba obuchwepheshe be-APD, kusekela izinhlelo zokusebenza ezintsha futhi kuthuthukise ukusebenza kwalezo ezikhona.
Ngokuqhubeka kocwaningo, singalindela ukuthuthukiswa okwengeziwe kobuchwepheshe be-APD Photodetector, ikakhulukazi ezindaweni ezifana nokunciphisa umsindo, ukwanda kwe-bandwidth, ukuthuthukiswa kokuzwela kanye nokwandiswa kokumbozwa. Lezi ntuthuko zizoqhubeka nokwenza i-APD ibe yingxenye ebalulekile emikhakheni evuthiwe njengezokuxhumana kanye nemikhakha ekhulayo njenge-quantum technology, izinhlelo ezizimele kanye nezinsimbi zesayensi ezithuthukisiwe.
