Imashini zipima foto za OFC2024

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

1. UCDAVIS ibona imiterere idasobanutse neza ya 1315.5nm idahuje imiterereicyuma gipima fotoifite ubushobozi buke cyane, bugereranywa ko ari 0.08fF. Iyo bias ari -1V (-2V), umugezi wijimye ni 0.72 nA (3.40 nA), kandi igipimo cyo gusubiza ni 0.93a /W (0.96a /W). Ingufu zuzuye za optique ni 2 mW (3 mW). Ishobora gushyigikira igerageza rya 38 GHz ryihuse ry'amakuru.
Ishusho ikurikira igaragaza imiterere ya AFP PD, igizwe n'umuraba uhujwe na Ge-on-Si fotodecteurhamwe n'umurongo w'imbere wa SOI-Ge uhuza imiterere ya > 90% hamwe n'ishusho ya < 10%. Inyuma ni Bragg reflector (DBR) ikwirakwijwe ifite ifoto ya > 95%. Binyuze mu gishushanyo cyiza cyo mu cyuho (imiterere yo guhuza imiterere y'icyiciro cyo kugaruka), ifoto ya AFP resonator ishobora gukurwaho, bigatuma Ge detector ibasha kwinjiza hafi 100%. Ku muyoboro wose wa 20nm w'uburebure bw'umurambararo wo hagati, R + T < 2% (-17 dB). Ubugari bwa Ge ni 0.6µm kandi ubushobozi bugereranywa ko ari 0.08fF.

2, Kaminuza ya Huazhong y'Ubumenyi n'Ikoranabuhanga yakoze germanium ya silikonifotodiode y'inkangu, umuyoboro w'itumanaho > 67 GHz, inyungu > 6.6. SACMAPD ipima fotoImiterere y'aho imiyoboro y'amazi ihurira ikorwa ku rubuga rwa silicon optique. Geranium y'imbere (i-Ge) na silicon y'imbere (i-Si) bitanga urwego rufata urumuri n'urwego rufata electron inshuro ebyiri, uko bikurikirana. Agace ka i-Ge gafite uburebure bwa 14µm gatanga ubushobozi bwo gufata urumuri ku gipimo cya 1550nm. Uduce duto twa i-Ge na i-Si tworohereza kongera ubucucike bwa photocurrent no kwagura umurambararo w'amazi munsi y'umuvuduko mwinshi wa bias. Ikarita y'amaso ya APD yapimwe kuri -10.6 V. Hamwe n'imbaraga z'urumuri zo kwinjira za -14 dBm, ikarita y'amaso y'ibimenyetso bya OOK bya 50 Gb/s na 64 Gb/s igaragara hepfo, naho SNR yapimwe ni 17.8 na 13.2 dB.

3. Ibikoresho bya IHP 8-inch BiCMOS pilote line bigaragaza germaniumPD ipima fotoifite ubugari bwa nm 100, ishobora gutanga ingufu z'amashanyarazi nyinshi cyane n'igihe gito cyane cyo gushyuha kw'ifoto. Ge PD ifite umuyoboro wa OE wa 265 GHz@2V@ 1.0mA DC photocurrent. Urugendo rw'imikorere rugaragara hepfo. Ikintu gikomeye ni uko implantation gakondo ya SI mixed ion irarekwa, kandi gahunda yo gushushanya ikura irafatwa kugira ngo hirindwe ingaruka zo kwinjizwa kwa 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 cyane. Kuri O-band. PD ifite A responsibility ya 0.57 A/W ifite munsi ya 1 dB PDL, mu gihe SOA-PD ifite responsibility ya 24 A/W ifite munsi ya 1 dB PDL. Bandwidth y'ibi byombi ni ~60GHz, kandi itandukaniro rya 1 GHz rishobora guterwa n'umuvuduko wa resonance wa SOA. Nta ngaruka y'icyitegererezo yagaragaye mu ishusho nyayo y'ijisho. SOA-PD igabanya imbaraga z'urumuri zikenewe ho 13 dB kuri 56 GBaud.

5. ETH ishyira mu bikorwa GaInAsSb/InP UTC-PD yongerewe mu bwoko bwa II, ifite umurambararo wa 60GHz @ zero bias n'imbaraga nyinshi zo gutanga umusaruro wa -11 DBM kuri 100GHz. Gukomeza ibyavuye mu bushakashatsi bwabanje, hakoreshejwe ubushobozi bwo gutwara electron bwa GaInAsSb. Muri iyi nyandiko, urwego rworoshye rwo gufata urumuri rurimo GaInAsSb ya 100 nm ifite umurambararo mwinshi na GaInAsSb ya 20 nm ifite umurambararo udafite umurambararo. Uru rwego rwa NID rufasha kunoza uburyo bwo gusubiza ibintu muri rusange ndetse runafasha kugabanya ubushobozi bwose bw'igikoresho no kunoza umurambararo. UTC-PD ya 64µm2 ifite umurambararo wa zero-bias wa 60 GHz, ingufu zo gutanga umusaruro za -11 dBm kuri 100 GHz, n'umurambararo wa saturation wa 5.5 mA. Iyo umurambararo wa reverse wa 3 V, umurambararo wiyongera ukagera kuri 110 GHz.

6. Innolight yashyizeho icyitegererezo cyo gusubiza inshuro nyinshi cya germanium silicon photodetector hashingiwe ku gusuzuma byimazeyo gukoresha ibikoresho, gukwirakwiza amashanyarazi n'igihe cyo kohereza ibikoresho bifotora. Bitewe n'uko hakenewe ingufu nyinshi zo kwinjira n'umurambararo mwinshi mu bikorwa byinshi, ingufu nyinshi zo kwinjira zizatera kugabanuka k'umurambararo, uburyo bwiza ni ukugabanya ubwinshi bw'umurambararo muri germanium binyuze mu miterere y'imiterere.

7, Kaminuza ya Tsinghua yashushanyije ubwoko butatu bwa UTC-PD, (1) imiterere ya bandwidth double drift layer (DDL) ya 100GHz ifite imbaraga nyinshi zo gusaza UTC-PD, (2) imiterere ya bandwidth double drift layer ya 100GHz (DCL) ifite ubushobozi bwinshi bwo gusubiza UTC-PD, (3) bandwidth ya 230 GHZ MUTC-PD ifite imbaraga nyinshi zo gusaza, Ku bintu bitandukanye bikoreshwa, imbaraga nyinshi zo gusaza, bandwidth nyinshi no gusubiza neza bishobora kuba ingirakamaro mu gihe kizaza mugihe cyinjiye mu gihe cya 200G.
