Yau bari mu kalli OFC2024masu daukar hoto, waɗanda galibi sun haɗa da GeSi PD/APD, InP SOA-PD, da UTC-PD.

1. UCDAVIS ya gane mai rauni resonant 1315.5nm mara simmetric Fabry-Perotmai daukar hototare da ƙaramin ƙarfin ƙarfi, an kiyasta ya zama 0.08fF. Lokacin da son zuciya ya kasance -1V (-2V), duhun halin yanzu shine 0.72 nA (3.40 nA), kuma ƙimar amsa shine 0.93a / W (0.96a / W). Cikakken ikon gani shine 2mW (3mW). Yana iya tallafawa gwaje-gwajen bayanai masu sauri na 38 GHz.
Zane mai zuwa yana nuna tsarin PD na AFP, wanda ya ƙunshi jagorar igiyar ruwa haɗe da Ge-on-Da photodetectortare da gaban SOI-Ge waveguide wanda ya cimma> 90% daidaitaccen yanayin daidaitawa tare da nuni na <10%. A baya shine mai rarraba Bragg reflector (DBR) tare da nuna haske na> 95%. Ta hanyar ingantaccen ƙirar rami (yanayin da ya dace da tafiya zagaye-zagaye), ana iya kawar da tunani da watsa resonator na AFP, wanda ke haifar da ɗaukar mai gano Ge zuwa kusan 100%. Sama da duka 20nm bandwidth na tsakiyar zangon zangon, R + T <2% (-17 dB). Nisa Ge shine 0.6µm kuma ana ƙididdige ƙarfin ƙarfin 0.08fF.

2, Jami'ar Kimiyya da Fasaha ta Huazhong ta samar da germanium siliconAvalanche photodiode, bandwidth>67 GHz, riba>6.6. Farashin SACMAPD photodetectorAn ƙera tsarin mahaɗar bututun a kan dandamali na gani na silicon. Intrinsic germanium (i-Ge) da silicon (i-Si) na ciki (i-Si) suna aiki azaman Layer mai ɗaukar haske da Layer biyu na lantarki, bi da bi. Yankin i-Ge tare da tsayin 14µm yana ba da garantin isassun ɗaukar haske a 1550nm. Ƙananan yankunan i-Ge da i-Si suna da kyau don haɓaka haɓakar hoto na yanzu da kuma fadada bandwidth a ƙarƙashin babban ƙarfin wutar lantarki. An auna taswirar ido na APD a -10.6 V. Tare da ikon shigarwa na -14 dBm, taswirar ido na 50 Gb / s da 64 Gb / s OOK sigina an nuna a kasa, kuma SNR da aka auna shine 17.8 da 13.2 dB. , bi da bi.

3. IHP 8-inch BiCMOS layin matukin jirgi yana nuna germaniumPD photodetectortare da faɗin fin kusan nm 100, wanda zai iya samar da mafi girman filin lantarki da mafi ƙarancin lokacin jigilar hoto. Ge PD yana da bandwidth na OE na 265 GHz@2V@ 1.0mA DC photocurrent. Ana nuna kwararar tsari a ƙasa. Babban fasalin shi ne cewa an yi watsi da shigar da ion na SI na gargajiya, kuma ana ɗaukar tsarin haɓakar haɓaka don guje wa tasirin dasa ion akan germanium. Yanayin duhu shine 100nA, R = 0.45A/W.
4, HHI yana nuna InP SOA-PD, wanda ya ƙunshi SSC, MQW-SOA da mai saurin hoto mai sauri. Don O-band. PD yana da amsawa na 0.57 A/W tare da ƙasa da 1 dB PDL, yayin da SOA-PD yana da amsawar 24 A/W tare da ƙasa da 1 dB PDL. bandwidth na biyu shine ~ 60GHz, kuma ana iya danganta bambancin 1 GHz zuwa mitar sautin SOA. Ba a ga tasirin tsari a ainihin hoton ido ba. SOA-PD yana rage ƙarfin gani da ake buƙata da kusan 13 dB a 56 GBaud.

5. ETH yana aiwatar da Nau'in II na inganta GaInAsSb / InP UTC-PD, tare da bandwidth na 60GHz@ sifili bias da babban ƙarfin fitarwa na -11 DBM a 100GHz. Ci gaba da sakamakon da ya gabata, ta amfani da ingantattun damar jigilar lantarki ta GaInAsSb. A cikin wannan takarda, ingantattun matakan sha sun haɗa da GaInAsSb mai ƙarfi na 100 nm da GaInAsSb na 20nm wanda ba a gama ba. Layer na NID yana taimakawa wajen haɓaka amsa gabaɗaya kuma yana taimakawa wajen rage ƙarfin ƙarfin na'urar gaba ɗaya da haɓaka bandwidth. 64µm2 UTC-PD yana da bandwidth na sifili-bias na 60 GHz, ikon fitarwa na -11 dBm a 100 GHz, da jikewar halin yanzu na 5.5mA. A juzu'i na 3 V, bandwidth yana ƙaruwa zuwa 110 GHz.

6. Innolight ya kafa samfurin amsa mitar na germanium silicon photodetector bisa cikakken la'akari da doping na'urar, rarraba wutar lantarki da lokacin canja wurin mai ɗaukar hoto. Saboda buƙatar babban ƙarfin shigarwa da babban bandwidth a cikin aikace-aikace da yawa, babban shigar da wutar lantarki na gani zai haifar da raguwa a cikin bandwidth, mafi kyawun aiki shine don rage ƙaddamar da ƙaddamarwa a cikin germanium ta hanyar ƙirar tsari.

7, Jami'ar Tsinghua ta tsara nau'ikan UTC-PD guda uku, (1) 100GHz bandwidth sau biyu drift Layer (DDL) tsarin tare da babban ƙarfin jikewa UTC-PD, (2) 100GHz bandwidth sau biyu drift Layer (DCL) tsarin tare da babban amsa UTC-PD .
