Ofc2024 phodethers-ka

Maanta aan eegno ATC2024PhotodeTetect, taas oo inta badan ay ku jiraan GESI PD / APD, INP SORA-PD, iyo UTC-PD.

1. Ucdavis wuxuu gartaa resonalt daciif ah 1315.5nm aan-ahayn faddarka aan sumadda lahayneegidoo leh tiro aad u yar, ayaa lagu qiyaasay inuu yahay 0.08ff. Marka eexda uu yahay -1V (-2v), xaadirka mugdiga ah waa 0.72 na (3.40 NA), oo heerka jawaabta waa 0.93a / W (0.96A / W). Awoodda lafdhabarta ee buuqa ayaa ah 2 mw (3 mw). Waxay taageeri kartaa 38 tijaabooyin xaruuro xawaare sare xawaare sare leh.
Jaantusyada soo socota ayaa muujineysa qaab dhismeedka AFP PD-ka, kaasoo ka kooban Ge-On-PhotoDeTodetatorcalkaIyada oo leh mowjad hore ee Soi-Ge Geas oo gaadhay> 90% qaab isku mid ah isku-darka iyadoo la adeegsanayo nooc ka mid ah <10%. Dhabarka dambe ayaa ah mid muujinaya iftiinka Bragg (DBR) oo leh milicsiga> 95%. Iyada oo loo marayo naqshadda daloolka ee wanaagsan (xaalad isdaba joog ah oo isku-darka wejiga), milicsiga iyo isu-gudbinta kadhigidda iyo P-ka AFP waa la baabi'in karaa, taasoo dhalisay in ay nuugaan qalabka gargaarada gebi ku dhawaad ​​100%. In ka badan dhammaan Wardwidth-ka ee 20NM ee mawjadda dhexe, R + T <2% (-17 dB). Widd-ka GE waa 0.6μm oo kartida loo qiyaaso waa 0.088ff.

2, Huzhorng Jaamacadda Sayniska iyo tikniyoolajiyadda ayaa soo saartay Germanium siliconPholalanche Photodiode, Bandwidth> 67 GHz, Held> 6.6. SacmPhotoDetoCher apdQaab-dhismeedka isgoyska Twipin ee Transverse waxaa lagu been abuurtay madal indhaha ku habboon silicon. Germanium Germanium (I-GE) iyo Insiosic Silicon (I-SI) ayaa u adeega maadaama nalka iftiinka lakabka iyo lakabka elektaroonigga ah, siday u kala horreeyaan. Gobolka I-Geedka oo leh dherer dhan 14 nooc ayaa dammaanad qaadaya nuugista iftiin ku filan 1550Nm. Gobollada yar ee I-I--SI-da ayaa u qalma kordhinta cufnaanta sawir-qaadista iyo ballaarinta faashadda ee hoos yimaada Volt-ka Sare. Khariidadda APD-ka APD waxaa lagu cabiray -10.6 V. Iyada oo leh fikrad indhaha ah -14 dBm, khariidadda indhaha ee 50 GB / s SNR-ga oo la cabiro ayaa ah 17.8 iyo 13.2 dB, siday u kala horreeyaan.

3. IHP 8-inji oo inji ah oo lagu tijaabiyo tas-hiilaadka BICTOMPD PhotoDodetatorcationoo leh ballaca 'Fing Ballal' qiyaastii 100 NM, oo abuuri kara garoonka korantada ugu sarreeya iyo sawir-qaadista ugu gaaban ee sawir qaadista. GE PD-ka wuxuu leeyahay wado waday 265 ghz @ 2v @ 1.0ma dc podemr. Qulqulka nidaamka ayaa lagu muujiyey hoosta. Muuqaalka ugu weyn ayaa ah in mushaarka dhaqanka ee isku-dhafka ah ee ION ee isku-dhafan ee ION laga tagay, iyo nidaamka koriinka ee kobaca ah ee loo yaqaan 'Etchling' la ansaxiyay si looga fogaado saameynta mushaarka ion ee ku saabsan Jarmalka. Mark madow waa 100Na, r = 0.45a / w.
4, HHI wuxuu soo bandhigayaa INP SORA-PD, oo ka kooban SSC, MQW-Soca iyo Photodetetort xawaare sare leh. Loogu talagalay o-band. PD waxay leedahay jawaabcelinta 0.57 a / w Bandwidth labada waa ~ 60ggz, farqiga u dhexeeya 1 Ghz waxaa loo aanayn karaa inta jeer ee ay is-heystaan ​​ee Soca. Wax saameyn ah oo qaab dhismeedka laguma arko muuqaalka indhaha ee dhabta ah. PD-ka Soa waxay yareysaa awoodda indhaha ee loo baahan yahay illaa 13 dB 56 Gbahauud.

5. Etc-PD-ka II ayaa hagaajisay Gearsb / Inp UTC-PD, oo leh bandwidth 60ghz @ Zero Sias iyo awood sare oo ah -11 dbm oo ah 100gh. Sii wadida natiijooyinkii hore, iyadoo la adeegsanayo awooda korantada ee Gethassb ee loo yaqaan 'Getssb' Waraaqdan, lakabyada cagaha ee indhaha ee lagu rakibay waxaa ka mid ah Getsusb oo culus oo 100 NM ah iyo koronto aan la furin oo ah 20 NM. Lakabkan dareenka ah wuxuu gacan ka geystaa hagaajinta jawaab celinta guud wuxuuna sidoo kale gacan ka geystaa yareynta guud ahaan dammaanadda aaladda loona wanaajiyo xarkaha. 64μmp2 UTC-PD-ka ayaa leh faashad eber ah oo ah 60 genz, oo ah awood wax soo saar ah oo ah -11 dbm oo ah 100 ghz, iyo culayska hadda jira 5.5 ma. Xiiqiseyn dhanka dambe ee 3 v, xarkaha ayaa kordhaya 110 ghz.

. Sababta oo ah baahida loo qabo awood-gelinta weyn iyo xadiidka sare ee codsiyada badan, soo-gelinta korantada indhaha ee weyn waxay sababi doontaa hoos udhac bandwidth, dhaqanka ugu fiican waa in la yareeyo waxyaabaha ku jira ee ku saabsan Jarmalka ee Jarmalka.

7, Jaamacadda Tsinghua ee loogu talagalay Saddex nooc oo ah UTC-PD, Bandwidth iyo jawaab-celinta sare waxay waxtar u yeelan kartaa mustaqbalka markii la galo 200g xilli.
