OFC2024 PhotoDetectors

Namuhla ake sibheke i-AC2024PhotoDeteectors, okubandakanya ikakhulukazi i-GESI PD / APD, i-INP SOA-PD, ne-UTC-PD.

1. Ucdavis ubona i-resonant ebuthakathaka engu-1315.5nm non-symmetric fabry-shotoI-PhotoDETETETETECETETETNgokusebenzisa amandla amancane kakhulu, kulinganiselwa ukuthi ube ngu-0.08FF. Lapho i-Bias is -1V (-2V), amanje amnyama akhona ngu-0.72 na (3.40 na (3.40 na), kanye nezinga lokuphendula ngu-0.93a / W (0.96A / W). Amandla agcwele ama-optical ngu-2 mw (3 mw). Ingasekela izivivinyo zedatha ephezulu engama-38 ghz.
Umdwebo olandelayo ukhombisa ukwakheka kwe-AFP PD, equkethe i-WaveGuide ehlanganisiwe ge-on-Bheka I-PhotoDectorNge-saveguide yangaphambili ye-SOI-GE efinyelela> Imodi engu-90% yemodi yokuhlanganisa nokuhlangana okungumbukiso we- <10%. I-MECPER iyi-BRAGG EBRAGG Reflector (DBR) enombukiso we- 95%. Ngomklamo we-caving olungiselelwe (ukuhambelana kwesigaba sokujikeleza kohambo), ukuboniswa kanye nokudluliselwa kwe-AFP resonator kungaqedwa, okuholela ekuhlolweni komtshina we-ge ukuze kucishe kube ngu-100%. Phezu kwe-10nm bandwidth ye-wavelength ephakathi nendawo, R + T <2% (-17 db). I-Ge Worth yi-0.6μm kanye ne-capacitance kulinganiselwa ukuthi ibe ngu-0.08FF.

2, Huazhong University of Science neTekhnoloji kwakhiqiza i-silicon germaniumI-Avalanche Photodiode, Bandwidth> 67 GHZ, zuza> 6.6. I-sacmI-PhotoDector ye-APDUkwakheka kwe-transverse pipin junction kwenziwa epulatifomu ye-silicon optical. I-Intrinsic Germanium (i-GE) kanye ne-silicon eyi-interricon (i-si) zisebenza njengesendlalelo sokukhanya esikhanyayo ne-electron ukuphinda ungqimba, ngokulandelana. Isifunda se-I-GE esine-14 μm siqinisekisa ukumuncwa kokukhanya okwanele ngo-1550nm. Izindawo ezincane ze-I-GE kanye nezifunda ze-SI Imephu yeso le-APD yalinganiswa ku -10.6 v. ngamandla okufaka okufakwayo we-1 dbm, imephu yeso yezinsuku ezingama-50 GB / s kanye ne-64 GB / s-34 no-13.8 no-13.2 DB, ngokulandelana.

3. I-IHP 8-inch Bicmos Filet Line Line Ibonisa i-GermaniumPD PhotoDepectorNgobubanzi be-FIN obuyi-100 NM, abangakhiqiza insimu kagesi ephezulu kakhulu kanye nesikhathi esifushane kunazo zonke ze-PhotoCarrier Drift. I-GE PD ine-OE bandwidth ka-265 GHZ @ 2V @ 1.0A DC PhotoCurent. Ukugeleza kwenqubo kuboniswa ngezansi. Isici esikhulu kunazo zonke ukuthi ukufakwa kwendabuko kwe-SIon okuhlanganisiwe kushiywe, futhi uhlelo lokukhula lokukhula luyamukelwa ukugwema ukuthonywa kwe-ion ukufakwa ku-germanium. Amanje amanje angamanje yi-100NA, R = 0.45A / W.
I-4, HHI ikhombisa i-INP SOA-PD, equkethe i-SSC, i-MQW-SOA ne-PhotoDetor ephezulu yejubane. Nge-O-band. I-PD inokuphendula okungu-0.57 a / w nge-1 db pdl, ngenkathi i-soa-pd inokuphendula okungama-24 a / w nge-1 dB PDL engaphansi kwe-1 db pdl. I-bandwidth yalokhu ezimbili ~ Awukho umphumela wephethini obonwa esithombeni sangempela samehlo. I-SOA-PD inciphisa amandla afunekayo afunwa yi-13 DB kwa-56 Gbaud.

5 Ukuqhubeka kwemiphumela eyedlule, kusetshenziswa amandla we-Valusb's Enhhanced Electron Transport Traxis. Kuleli phepha, izingqimba zokutholwa ezilungiselelwe zifaka i-GAITASB ekhuliswe kakhulu ye-100 nm ne-GAITASB engekho emthethweni engama-20 nm. Isendlalelo se-NID sisiza ukuthuthukisa ukuphendula okuphelele futhi sisiza ekunciphiseni amandla okukhokhwa kwemali ephelele yedivayisi futhi sithuthukise umkhawulokudonsa. I-64μm2 UTC-PD ine-bandwidth ye-zero-bias ye-60 GHz, amandla okukhipha angu -11 dbm ku-100 GHZ, kanye ne-sackation yamanje ka-5.5 Ma. Ekuhloleni okubuyela emuva kwe-3 v, i-bandwidth inyuka ibe ngu-110 GHz.

I-6. I-Innollight isungule imodeli yokuphendula imvamisa ye-Germanium Silicon PhotoDetector ngesisekelo sokucabanga ngokugcwele i-doping yedivayisi, ukusatshalaliswa kwensimu kagesi kanye nesikhathi sokudlulisa senethiwekhi esikhiqizwe ngezithombe. Ngenxa yesidingo samandla amakhulu okufaka kanye ne-bandwidth ephezulu kwizicelo eziningi, ukufakwa kwamandla amakhulu akwa-optical kuzodala ukwehla kwe-bandwidth, umkhuba omuhle kakhulu ukunciphisa ukugxila kwe-geramonium.

7, iTsinghua University iye yaklama izinhlobo ezintathu ze-UTC-PD, (1) i-100GHz bandwidth Double Drift ungqimba (DDL) ngesakhiwo esiphakeme se-UTC-PD, (3) i-50) i-530 i-ghz bandwidth ungqimba ((3) Izimo ezihlukile zesicelo, amandla aphezulu okugcwala, ukuphakama I-bandwidth kanye nokuphendula okuphezulu kungaba wusizo esikhathini esizayo lapho ufaka inkathi ye-200G.
