OFC2024 ifotora

Uyu munsi reka turebe OFC2024gufotora, zirimo cyane cyane GeSi PD / APD, InP SOA-PD, na UTC-PD.

1.gufotorahamwe n'ubushobozi buto cyane, bugereranijwe ni 0.08fF. Iyo kubogama ari -1V (-2V), umwijima wijimye ni 0,72 nA (3.40 nA), naho igisubizo ni 0.93a / W (0.96a / W). Imbaraga za optique zuzuye ni mW 2 (3 mW). Irashobora gushyigikira 38 GHz yihuta yamakuru yamakuru.
Igishushanyo gikurikira cyerekana imiterere ya AFP PD, igizwe na waveguide ihujwe na Ge-on-Si Photodetectorhamwe imbere SOI-Ge waveguide igera kuri> 90% yuburyo bujyanye no guhuza hamwe na <10%. Inyuma ni ikwirakwizwa rya Bragg (DBR) hamwe na> 95%. Binyuze mu gishushanyo mbonera cya cavity (icyiciro-cyurugendo rwo guhuza icyiciro), kugaragariza no gukwirakwiza resonator ya AFP birashobora kuvaho, bikaviramo kwinjiza disiketi ya Ge hafi 100%. Kurenza umurongo wa 20nm wuburebure bwumurongo wo hagati, R + T <2% (-17 dB). Ubugari bwa Ge ni 0,6µm naho ubushobozi bugereranijwe ni 0.08fF.

2, Huazhong University of Science and Technology yakoze silicon germaniumavalanche Photodiode, umurongo mugari> 67 GHz, kunguka> 6.6. SACMAPD ifotoraimiterere ya transverse pipin ihuza yahimbwe kuri platifike optique. Imbere ya germanium (i-Ge) na silikoni yimbere (i-Si) ikora nk'urwego rukurura urumuri hamwe na elegitoroniki ikubye kabiri. Agace ka i-Ge gafite uburebure bwa 14µm gatanga urumuri ruhagije kuri 1550nm. Uturere duto twa i-Ge na i-Si bifasha mu kongera ubwinshi bwamafoto no kwagura umurongo mugari wa voltage ndende. Ikarita y'amaso ya APD yapimwe kuri -10.6 V. Hifashishijwe imbaraga za optique ya -14 dBm, ikarita yijisho ryibimenyetso 50 Gb / s na 64 Gb / s OOK irerekanwa hepfo, naho SNR yapimwe ni 17.8 na 13.2 dB .

3. IHP 8-cm ya BiCMOS yumurongo wicyitegererezo yerekana germaniumPD ifotorahamwe n'ubugari bwa fin hafi ya 100 nm, ishobora kubyara amashanyarazi maremare hamwe nigihe gito cyo gufotora. Ge PD ifite umurongo wa OE wa 265 GHz @ 2V @ 1.0mA DC ifotora. Inzira igenda irerekanwa hepfo. Ikintu kinini kiranga nuko SI ivanze na ion gakondo iterwa, kandi gahunda yo gukura ikura kugirango hirindwe ingaruka ziterwa na ion kuri germanium. Umuyoboro wijimye ni 100nA, R = 0.45A / W.
4, HHI yerekana InP SOA-PD, igizwe na SSC, MQW-SOA na Photodetector yihuta. Kuri O-band. PD ifite igisubizo cya 0.57 A / W ifite munsi ya 1 dB PDL, mugihe SOA-PD ifite ibisubizo bya 24 A / W hamwe na 1 dB PDL. Umuyoboro mugari wa bombi ni ~ 60GHz, kandi itandukaniro rya 1 GHz rishobora kwitirirwa resonance yumurongo wa SOA. Nta ngaruka zishusho zagaragaye mumashusho yukuri. SOA-PD igabanya ingufu za optique zisabwa hafi 13 dB kuri 56 GBaud.

5. Gukomeza ibisubizo byabanjirije, ukoresheje GaInAsSb yongerewe ubushobozi bwo gutwara electron. Muri iyi nyandiko, uburyo bwiza bwo kwinjiza ibintu burimo GaInAsSb yuzuye cyane ya 100 nm na GaInAsSb idafunze ya 20 nm. Igice cya NID gifasha kunoza imikorere muri rusange kandi ikanafasha kugabanya ubushobozi rusange bwibikoresho no kunoza umurongo. 64µm2 UTC-PD ifite umurongo wa zeru-bias wa 60 GHz, imbaraga zisohoka -11 dBm kuri 100 GHz, hamwe na 5.5 mA. Kubogama kubogamye kwa 3 V, umurongo wiyongera kuri 110 GHz.

6. Bitewe no gukenera imbaraga nini zo kwinjiza hamwe nubunini buke mubisabwa byinshi, ingufu nini za optique zinjiza bizatera kugabanuka kwagutse, imyitozo myiza ni ukugabanya ubwikorezi bwabatwara muri germanium hakoreshejwe igishushanyo mbonera.

7, Kaminuza ya Tsinghua yateguye ubwoko butatu bwa UTC-PD, (1) 100GHz yumurongo wa kabiri wa drift layer (DDL) ifite imbaraga zuzuye zuzuye UTC-PD, (2) 100GHz yumurongo wa kabiri (DCL) hamwe nubwitonzi bukomeye UTC-PD ,.
