OFC2024 Photodetectors

Niaj hnub no cia saib ntawm OFC2024photodetectors, uas feem ntau yog nrog Gesi PD / APD, INP SOA-PD, thiab UTC-PD.

1. UCDavis paub tias tus resononant uas tsis muaj zog 1315.5nm tsis yog-symmetric fabry-potphotodetectornrog kev ntsuas me me, kwv yees kom tau txais 0. 0.0ff. Thaum lub bias yog -1v (-2v (-2v), qhov tsaus ntuj tam sim no yog 0.72 na (3.40 thiab tus nqi teb yog 0.93A / w). Lub zog tsim kho kho qhov muag yog 2 mW (3 mW). Nws tuaj yeem txhawb 38 GHz High-ceev cov ntaub ntawv sim.
Cov duab hauv qab no qhia cov qauv ntawm AFP PD, uas muaj ntawm WaveGuide Coupled ge-onSI PhotodetectorNrog rau pem hauv ntej soi-ge waveGuide uas ua tiav> 90% hom txuam nrog txuas nrog kev xav txog <10%. Lub nraub qaum yog muab faib rau Bragg Reactor (DBR) nrog kev xav txog ntawm> 95%. Los ntawm kev tsim kho kab noj hniav optimized (ncig-taug kev theem sib txuam), qhov kev cuam tshuam thiab kev nqus ntawm ge ntes mus ze li 100%. Dhau tag nrho 20nm bandwidth ntawm lub hauv paus wavelength, r + t <2% (-17 dB). Tus ge dav yog 0.6μm thiab lub capacitance yog kwv yees kom tau 0.08ff.

2, Huazhong University of Science thiab Tshuab tsim cov khoom lag luam siliconAvalanche photodiode, bandwidth> 67 GHz, tau> 6.6. Cov SacmAd PhotodetectorTus qauv ntawm transverse pipin kev sib deev yog fabricated ntawm silicon kho qhov muag. Intrinsic germanium (i-ge) thiab intrinsic silicon (I-si) ua lub teeb nqus cov txheej thiab hluav taws xob doubling txheej, ntsig txog. Qhov chaw I-GE nrog ib qhov ntev ntawm 14μm tau lees tias muaj kev nqus lub teeb kom txaus ntawm 1550nm. Cov cheeb tsam I-ge thiab cov kab ge thiab cov kab ge thiab cov kab ntawv thiab cov si-Si-si tau ntau dua los nce cov ntawv photwicity thiab nthuav dav bandwidth nyob rau hauv high bias bias. Daim ntawv qhia APD daim duab muag tau raug ntsuas ntawm -10.6 V. nrog rau lub tswv yim kho qhov muag ntawm 50 GB / S thiab 64 GB / S thiab ntsuas SNR yog 17.8 thiab 13.2 DB , ntsig txog.

3. IHP 8-nti Bicmos Pilot cob cov chaw tau qhia txog cov khoom lag luam GermanPd photoodetectorNrog cov ntsiab lus pom ntawm txog 100 nm, uas tuaj yeem tsim cov hluav taws xob siab tshaj plaws thiab cov ntawv luv tshaj plaws los ntawm lub sijhawm. GH Pd muaj OE Bandwidth ntawm 265 GHz @ 2V @ 2V @ 1.0ma DC Photoocurrent. Cov txheej txheem ntws yog qhia hauv qab no. Qhov loj tshaj plaws yog tias cov tsoos Si sib xyaw ua ke yog tso tseg, thiab cov phiaj xwm kev loj hlob yog los tiv thaiv kev cuam tshuam ntawm ion immantation ntawm garanium. Tsaus tam sim no yog 100NA, R = 0.45A / W.
4, hhi showcases inp soa-pd, muaj ntawm SSC, MQW-soa thiab kev kub ceev photodetector. Rau o-band. Pd muaj kev teb tau zoo ntawm 0.57 A / W nrog tsawg dua 1 DB PDL, Pd muaj lub luag haujlwm ntawm 24 DB PDL. Lub bandwidth ntawm ob yog ~ 60ghz, thiab qhov sib txawv ntawm 1 GHz tuaj yeem ntaus nqi rau lub sijhawm uas tau rov qab los ntawm SOA. Tsis muaj qauv qauv tau pom hauv cov duab tiag tiag. Lub Soa-Pd txo cov hwj chim xav tau ntawm kwv yees li 13 dB ntawm 56 GBAd.

5. EQog yam khoom siv II txhim kho tau txais cov khoom / INP UTC-PD, nrog rau bandwidth ntawm 60gh bias thiab lub zog loj ntawm -11 DBM ntawm 100GHz. Txuas ntxiv ntawm cov txiaj ntsig yav dhau los, siv cov Gassassb txhim kho hluav taws xob muaj peev xwm. Hauv daim ntawv no, txoj kev ua tiav zoo suav nrog cov doped hnyav tau cov dopsol ntawm 100 nm thiab undoped reassawb ntawm 20 nm. Nid txheej pab txhim kho tag nrho lub luag haujlwm thiab tseem pab txo cov kev muaj peev xwm ntau dua ntawm lub cuab yeej thiab txhim kho bandwidth. Lub 64μm2 utc-PD tau muaj xoom-kev bias bandwidth ntawm 60 GHz, ib qho tso zis lub zog ntawm -11 DBM ntawm 100 GHz, thiab kev muaj peev xwm ua tau ntawm 5.5 ma. Ntawm ib rov qab bias ntawm 3 V, Bandwidth nce mus rau 110 GHz.

6. Tsis muaj peev xwm tsim cov zaus teb cov qauv ntawm German silicia silicon photoappor ntawm doping ntaus ntawv thiab yees duab hluav taws xob xa sijhawm. Vim tias qhov xav tau rau cov hwj chim tawm loj thiab bandwidth siab nyob rau hauv ntau cov ntawv thov yuav ua rau txo cov cab kuj siab hauv German los ntawm kev tsim qauv txheej txheem.

7, Tsinghua University tau tsim peb hom UTC-PD, (1) 100 Txheej Txheem Txheej Txheem (DCL) . bandwidth thiab cov lus qhia tau zoo yuav pab tau zoo nyob rau yav tom ntej thaum nkag mus 200g era.
