OFC2024 photodetectors

Nhasi ngatitarisei kuOFC2024photodetectors, iyo inonyanya kusanganisira GeSi PD/APD, InP SOA-PD, uye UTC-PD.

1. UCDAVIS inoona isina simba resonant 1315.5nm isiri-symmetric Fabry-Perotphotodetectorine diki diki kugona, inofungidzirwa kuve 0.08fF. Kana iyo bias iri -1V (-2V), yakasviba ikozvino 0.72 nA (3.40 nA), uye chiyero chekupindura chiri 0.93a / W (0.96a / W). Iyo saturated optical simba ndeye 2 mW (3 mW). Inogona kutsigira 38 GHz yakakwirira-kumhanya data kuyedza.
Iyo inotevera dhizaini inoratidza chimiro cheAFP PD, iyo ine waveguide yakasanganiswa Ge-on-Ndiwo photodetectorine kumberi SOI-Ge waveguide inowana> 90% modhi inoenderana nekubatanidza ine reflectivity ye <10%. Kumashure kwakagoverwa Bragg reflector (DBR) ine reflectivity ye> 95%. Kuburikidza neyakagadziridzwa dhizaini dhizaini (yekutenderera-yekutenderera-chikamu chinoenderana mamiriro), kuratidzira uye kutapurirana kweAFP resonator kunogona kubviswa, zvichikonzera kutorwa kweGe detector kusvika kunosvika zana%. Pamusoro peiyo yese 20nm bandwidth yepakati wavelength, R+T <2% (-17 dB). Iyo Ge yakafara ndeye 0.6µm uye capacitance inofungidzirwa kuve 0.08fF.

2, Huazhong University of Science and Technology yakagadzira silicon germaniumAvalanche photodiode, bandwidth> 67 GHz, kuwana> 6.6. Iye SACMAPD photodetectorchimiro chekuchinjika pipin junction inogadzirwa pasilicon optical chikuva. Intrinsic germanium (i-Ge) uye intrinsic silicon (i-Si) inoshanda seyerenje inotora mwenje uye maerekitironi yakapetwa kaviri, zvichiteerana. Iyo i-Ge dunhu ine hurefu hwe14µm inovimbisa kukwana kwakaringana kunyudzwa kwechiedza pa1550nm. Iwo madiki e-i-Ge uye i-Si matunhu akanakira kuwedzera iyo photocurrent density uye kuwedzera bandwidth pasi peyakanyanya bias voltage. Mepu yeziso yeAPD yakayerwa pa -10.6 V. Nekupinza kwemagetsi e -14 dBm, mepu yeziso ye50 Gb / s uye 64 Gb / s OOK zviratidzo inoratidzwa pasi apa, uye SNR yakayerwa ndeye 17.8 uye 13.2 dB , zvichiteerana.

3. IHP 8-inch BiCMOS pilot line zvivakwa zvinoratidza germaniumPD photodetectorine fin hupamhi hunosvika zana nm, iyo inogona kuburitsa iyo yepamusoro yemagetsi munda uye ipfupi fotocarrier drift nguva. Ge PD ine OE bandwidth ye265 GHz@2V@ 1.0mA DC photocurrent. Nzira yekuyerera inoratidzwa pasi apa. Chinhu chikuru ndechekuti iyo yechinyakare SI yakasanganiswa ion kuisirwa yakasiiwa, uye kukura etching chirongwa chinogamuchirwa kudzivirira pesvedzero yeion implantation pagermanium. Iyo yakasviba ikozvino 100nA,R = 0.45A /W.
4, HHI inoratidza InP SOA-PD, inosanganisira SSC, MQW-SOA uye high speed photodetector. YeO-band. PD ine A responsiveness ye0.57 A/W ine isingasviki 1 dB PDL, nepo SOA-PD ine inopindura ye24 A/W ine isingasviki 1 dB PDL. Iyo bandwidth yevaviri i ~ 60GHz, uye musiyano we1 GHz unogona kuverengerwa kune resonance frequency yeSOA. Hapana maitiro emuenzaniso akaonekwa mumufananidzo chaiwo weziso. Iyo SOA-PD inoderedza inodiwa optical simba neinenge 13 dB pa56 GBaud.

5. ETH zvishandiso Rudzi rwechipiri rwakanatsiridza GaInAsSb/InP UTC-PD, ine bandwidth ye60GHz@ zero bias uye simba repamusoro rinobuda -11 DBM pa100GHz. Kuenderera mberi kwezvakamboitika, uchishandisa GaInAsSb's yakagadziridzwa maerekitironi ekufambisa masimba. Mubepa rino, iwo akakwenenzverwa absorption layers anosanganisira yakanyanya doped GaInAsSb ye100 nm uye isina kuvhurwa GaInAsSb ye20 nm. Iyo NID layer inobatsira kuvandudza kuterera kwese uye zvakare inobatsira kudzikisa iyo yakazara capacitance yechishandiso uye kugadzirisa bandwidth. Iyo 64µm2 UTC-PD ine zero-bias bandwidth ye60 GHz, simba rekubuda -11 dBm pa100 GHz, uye saturation ikozvino ye5.5 mA. Pakurebesa bias ye3 V, iyo bandwidth inowedzera kusvika ku110 GHz.

6. Innolight yakagadzira frequency response modhi yegermanium silicon photodetector pahwaro hwekunyatsofunga nezvechigadzirwa chedoping, electric field distribution uye photo-generated carrier transfer time. Nekuda kwekudiwa kwesimba rakakura rekupinza uye yakakwirira bandwidth mune akawanda maapplication, hombe optical simba rekuisa richakonzera kuderera kwebandwidth, yakanakisa tsika ndeyekudzikisa mutakuri wekutengesa mugermanium nekugadzirwa kwemaitiro.

7, Tsinghua University yakagadzira marudzi matatu eUTC-PD, (1) 100GHz bandwidth kaviri drift layer (DDL) chimiro chine simba rekuzadza UTC-PD, (2) 100GHz bandwidth double drift layer (DCL) chimiro chine huremu hwepamusoro UTC-PD. , (3) 230 GHZ bandwidth MUTC-PD ine simba guru rekuzadza, Nokuda kwezviitiko zvakasiyana-siyana zvekushandiswa, simba rekuzadza, kukwirira kwepamusoro uye kupindura kwakanyanya kunogona kubatsira mune ramangwana paunopinda munguva ye200G.
