Daim duab hauv qab no qhia txog cov qauv ntawm AFP PD, uas muaj cov lus qhia waveguide txuas nrog Ge-on-Yog photodetectornrog rau pem hauv ntej SOI-Ge waveguide uas ua tiav> 90% hom kev sib txuas nrog kev cuam tshuam ntawm <10%. Lub rear yog ib tug faib Bragg reflector (DBR) nrog ib tug reflectivity ntawm> 95%. Los ntawm kev tsim kho kom zoo nkauj kab noj hniav (ib puag ncig-tawm mus rau theem sib piv), qhov kev xav thiab kev sib kis ntawm AFP resonator tuaj yeem raug tshem tawm, ua rau kev nqus ntawm Ge detector mus txog ze li 100%. Tshaj tag nrho 20nm bandwidth ntawm nruab nrab wavelength, R + T <2% (-17 dB). Qhov dav Ge yog 0.6µm thiab lub peev xwm kwv yees yog 0.08fF.

2, Huazhong University of Science thiab Technology tsim ib silicon germaniumavalanche photodiode, bandwidth> 67 GHz, nce> 6.6. The SACMAPD photodetectorqauv ntawm transverse pipin hlws ris yog fabricated ntawm silicon optical platform. Intrinsic germanium (i-Ge) thiab intrinsic silicon (i-Si) ua haujlwm raws li lub teeb absorbing txheej thiab electron ob txheej txheej, feem. Lub cheeb tsam i-Ge nrog qhov ntev ntawm 14µm lav lub teeb txaus ntawm 1550nm. Cov cheeb tsam me me ntawm i-Ge thiab i-Si yog qhov tsim nyog los ua kom cov photocurrent ntom ntom thiab nthuav dav bandwidth nyob rau hauv siab tsis ncaj voltage. APD lub qhov muag daim ntawv qhia tau ntsuas ntawm -10.6 V. Nrog rau lub zog input optical ntawm -14 dBm, daim ntawv qhia qhov muag ntawm 50 Gb / s thiab 64 Gb / s OOK cov cim qhia hauv qab no, thiab ntsuas SNR yog 17.8 thiab 13.2 dB , raws.

3. IHP 8-nti BiCMOS pilot kab cov chaw qhia txog germaniumPD photodetector muajnrog fin dav ntawm txog 100 nm, uas tuaj yeem tsim qhov hluav taws xob siab tshaj plaws thiab lub sijhawm luv tshaj photocarrier drift. Ge PD muaj OE bandwidth ntawm 265 GHz @ 2V @ 1.0mA DC photocurrent. Cov txheej txheem khiav yog qhia hauv qab no. Qhov loj tshaj plaws feature yog tias cov tsoos SI tov ion implantation raug tso tseg, thiab txoj kev loj hlob etching tswvyim yog saws kom tsis txhob muaj kev cuam tshuam ntawm ion implantation ntawm germanium. Qhov tsaus nti tam sim no yog 100nA, R = 0.45A / W.
4, HHI showcases InP SOA-PD, muaj xws li SSC, MQW-SOA thiab kev kub ceev photodetector. Rau O-band. PD muaj cov lus teb ntawm 0.57 A / W nrog tsawg dua 1 dB PDL, thaum SOA-PD muaj qhov ua haujlwm ntawm 24 A / W nrog tsawg dua 1 dB PDL. Qhov bandwidth ntawm ob yog ~ 60GHz, thiab qhov sib txawv ntawm 1 GHz tuaj yeem raug ntaus nqi rau qhov resonance zaus ntawm SOA. Tsis muaj qhov txawv txav tau pom hauv daim duab qhov muag tiag tiag. SOA-PD txo qhov xav tau lub zog kho qhov muag los ntawm 13 dB ntawm 56 GBaud.

5. ETH siv hom II txhim kho GaInAsSb/InP UTC-PD, nrog lub bandwidth ntawm 60GHz @ xoom bias thiab lub zog tso zis siab ntawm -11 DBM ntawm 100GHz. Kev txuas ntxiv ntawm cov txiaj ntsig yav dhau los, siv GaInAsSb qhov kev txhim kho hluav taws xob thauj khoom muaj peev xwm. Nyob rau hauv daim ntawv no, qhov optimized absorption txheej muaj xws li ib tug hnyav doped GaInAsSb ntawm 100 nm thiab ib tug undoped GaInAsSb ntawm 20 nm. NID txheej pab txhim kho tag nrho cov lus teb thiab tseem yuav pab txo qis tag nrho cov peev txheej ntawm cov cuab yeej thiab txhim kho bandwidth. 64µm2 UTC-PD muaj xoom-bias bandwidth ntawm 60 GHz, tso zis zog ntawm -11 dBm ntawm 100 GHz, thiab saturation tam sim no ntawm 5.5 mA. Ntawm qhov rov qab tsis zoo ntawm 3 V, qhov bandwidth nce mus rau 110 GHz.

6. Innolight tau tsim cov qauv lus teb zaus ntawm germanium silicon photodetector raws li kev txiav txim siab tag nrho cov khoom siv doping, hluav taws xob kev faib hluav taws xob thiab cov khoom siv hluav taws xob hloov lub sijhawm. Vim tias qhov xav tau ntawm lub zog nkag loj thiab siab bandwidth hauv ntau daim ntawv thov, cov khoom siv hluav taws xob kho qhov muag loj yuav ua rau txo qis bandwidth, qhov kev coj ua zoo tshaj plaws yog txo cov cab kuj concentration hauv germanium los ntawm kev tsim qauv.

7, Tsinghua University tsim peb hom UTC-PD, (1) 100GHz bandwidth ob chav drift txheej (DDL) qauv nrog siab saturation zog UTC-PD, (2) 100GHz bandwidth ob chav drift txheej (DCL) qauv nrog siab teb UTC-PD , (3) 230 GHZ bandwidth MUTC-PD nrog lub zog saturation siab, Rau qhov sib txawv ntawm daim ntawv thov scenarios, siab saturation zog, siab bandwidth thiab siab teb tej zaum yuav pab tau rau yav tom ntej thaum nkag mus rau 200G era.
