Oftatu ya 2524

Uyu munsi reka turebe kuri 024amafoto, ahanini harimo GESI PD / APD, INP SOA-PD, na UTC-PD.

1. Ucdavus akurikije resonant ikomeye 1315.5nm itari-symmetric fabry-perotPhotodetetectorHamwe no kubona ubushobozi buke cyane, bigera kuri 0.08ff. Iyo kubogama ari -1V (-2v), ikigezweho ni 0.72 na (3.40 na (3.40 na (3.40 na 0.93a / w (0.96a / W). Imbaraga za Optique zifite ubumenyi 2 MW (3 mw). Irashobora gushyigikira 38 ghz yihuta cyane.
Igishushanyo gikurikira cyerekana imiterere ya AFP PD, igizwe na waveguide coupUse ge-on-SI PhotodetectorHamwe na Soi-Ge WavegageGgaide igera> 90% muburyo buhuye na comping hamwe nuburyo bwa <10%. Inyuma ni ikwirakwizwa rya bragg ryatanzwe (DBR) hamwe nuburyo> 95%. Binyuze mu gishushanyo mbonera cyoroshye (icyiciro cyo kuzenguruka gihuza imiterere), gutekereza no kwanduza ospomator ya AFP birashobora kuvaho, bikavamo kwinjiza Gereranya hafi 100%. Hejuru ya 20nm igdeth yumurongo wo hagati, r + t <2% (-17 db). Ubugari bwa GE ni 0.6μm hamwe nubushobozi bugereranijwe kuba 0.08ff.

2, kaminuza ya siyansi n'ikoranabuhanga yabyaye Ikidage cya SiliconAvalanche Photodiode, umurongo wa bandwidth> 67 ghz, inyungu> 6.6. IsakoshiAPD PhotodetetectorImiterere yububiko bwa pipin ihimbano kuri silicon optique. Ikidage cyinjira (I-GE) na silicon yinjira (I-si) bikaba urumuri rukurura urwego na electron igice cyo gusakuza. Agace ka I-Ge kariho kavukire 14μm gare zishyigikira urumuri ruhagije kuri 1550nm. Uturere duto muri I-Ge na I-Sida dufatanije kongera ubucucike bwo kongera ubucucike kandi bwagura umurongo unyura munsi ya voltage yo hejuru. Ikarita yijisho rya APD yapimwe kuri -10.6 V. Hamwe na winjiza imbaraga za optique ya -14 dbm, ibimenyetso byamaso ya 50 gb / s hamwe na snr yapimwe ni 17.8 na 13.2 DB.

3. IHP 8-Inch Bicmos Imirongo yumurongo yerekana ikidagePD Photodetectorhamwe nubugari bwa NM ya NM 100, bushobora kubyara amashanyarazi menshi nibihe bigufi bya fotografir. Ge pd afite oe umurongo wa 265 ghz @ 2V @ 1.0MA DC PHAPECURTRED. Inzira itunganijwe irerekanwa hepfo. Ikiranga kinini ni uko ubuda gakondo sivanze Ion detentation iratereranwa, kandi gahunda yo gutora yashyikirijwe kwirinda ingaruka za ion scinontation yubudage. Ikibanza cyijimye ni 100na, r = 0.45a / w.
4, HHI PhowCase Isp Soa-Pd, igizwe na SSC, MQW-SOA na Photodetetector yihuta. Kuri o-itsinda. PD ifite inshingano za 0.57 A / W hamwe na 1 DB PDL, mugihe soa-pd ifite inshingano za 24 a / w hamwe na 1 db pdl. Umuyoboro wa bombi ni ~ 60GHZ, kandi itandukaniro rya 1 ghz rishobora guterwa na resasil yimisatsi ya SOA. Nta ngaruka zifatika zagaragaye mumashusho afatika. Soa-pd igabanya imbaraga zisabwa zisabwa na 13 db kuri 56 gbaud.

5. Gukomeza Ibisubizo byabanjirije, ukoresheje ubushobozi bwa RWANESB byazamuye ubushobozi bwo gutwara abantu. Muri iyi mpapuro, ibice byinjira neza birimo inyungu zikoreshwa cyane na nm ya NM 100 hamwe nunguka kugorora rya 20 nm. Igice cyipitwa gifasha kunoza rusange kandi gifasha kugabanya ubushobozi rusange bwibikoresho no kunoza umurongo. 64μm2 UTC-PD ifite umurongo wa zeru-boais, ibisohoka imbaraga -11 dbm kuri 100 ghz, nubwuzure buri 5.5 ma. Kubogama bitandukanya 3 v, igitambaro cyiyongera kuri 110 ghz.

6. Munsitara yashyizeho icyitegererezo cyo gusubiza umuvuduko wubudage Photodetector yubudage hashingiwe ku gikoresho cyo gusuzuma neza, gukwirakwiza amashanyarazi no gukwirakwiza amashanyarazi no kwinjiza amafoto. Bitewe nibikenewe byinjiza imbaraga ninkumi nyinshi mubisobanuro byinshi, ibyinjijwe binini byinjiza bizatera kugabanuka kwa bandwidth, imyitozo myiza ni ukugabanya kwibanda kubudage kubishushanyo mbonera.

7, Tsinghua Kaminuza eshatu za UTC-PD, (1) Urutonde rwibintu bibiri Imbaraga, imitako yo hejuru no kwishura cyane birashobora kuba ingirakamaro mugihe kizaza mugihe winjiye muri 200G.
