Sisitemu yibikoresho bya Photonic

Silicon Photonics ni disipuline ikoresha imiterere ya planar ishingiye kubikoresho bya silicon kugirango yerekane urumuri kugirango igere kumirimo itandukanye. Turibanda hano kubikorwa bya silicon Photonics mugukora transmitter hamwe niyakira kubitumanaho bya fibre optique. Nkuko bikenewe kongeramo itumanaho ryinshi kumurongo watanzwe, ikirenge cyatanzwe, hamwe nigiciro cyatanzwe cyiyongera, fotonike ya silicon iba nziza mubukungu. Kubice byiza,tekinoroji yo guhuzabigomba gukoreshwa, kandi transcevers nyinshi zihuza uyumunsi zubatswe hifashishijwe LiNbO3 / planar yumucyo-wumuzunguruko (PLC) modulator hamwe niyakira rya InP / PLC.

Igishushanyo 1: Yerekana uburyo bukoreshwa bwa fotonike yumuzingi (PIC) sisitemu yibikoresho.

Igishushanyo 1 kirerekana sisitemu ya PIC izwi cyane. Uhereye ibumoso ugana iburyo ni silika ishingiye kuri silika PIC (izwi kandi nka PLC), insulire ishingiye kuri silicon PIC (silicon Photonics), lithium niobate (LiNbO3), na III-V itsinda PIC, nka InP na GaAs. Uru rupapuro rwibanze kuri fotonike ishingiye kuri silicon. Murisilicon Photonics, ikimenyetso cyumucyo kigenda cyane muri silicon, gifite intera itaziguye ya 1.12 ya electron ya electron (hamwe nuburebure bwa microne 1,1). Silicon ihingwa muburyo bwa kristu nziza mu itanura hanyuma igabanywamo wafer, uyumunsi ubusanzwe ni mm 300 z'umurambararo. Ubuso bwa wafer burahinduka okiside kugirango ikore silika. Imwe muri wafer yatewe ibisasu na hydrogène kuri ubujyakuzimu. Wafers ebyiri noneho zishyirwa mu cyuho kandi ibice bya oxyde bihuza. Inteko isenya umurongo wa hydrogène ion. Igice cya silikoni kumeneka noneho gisizwe neza, amaherezo kigasigara igice gito cya kristalline Si hejuru ya wafer ya silicon “intoki” idahwitse hejuru ya silika. Imiyoboro ya Waveguide ikozwe muriki gice cyoroshye. Mugihe ibyo bikoresho bya silikoni ishingiye kuri silicon (SOI) ituma igihombo gito cya silicon Photonics waveguide ishoboka, mubyukuri ikoreshwa cyane mumashanyarazi make ya CMOS kubera amashanyarazi make batanga.

Hariho uburyo bwinshi bushoboka bwa silikoni ishingiye kuri optique ya optique, nkuko bigaragara ku gishushanyo cya 2. Ziratandukanye kuva microscale germanium-dope silica waveguides kugeza nanoscale Silicon Wire waveguides. Muguhuza germanium, birashoboka gukoragufotorano kwinjiza amashanyaraziabayobora, kandi birashoboka ndetse na optique yongerera imbaraga. Mugukata silicon, anmoderi nzizairashobora gukorwa. Hasi uhereye ibumoso ugana iburyo ni: silicon wire waveguide, silicon nitride waveguide, silicon oxynitride waveguide, silicon silge ridge waveguide, silicon silike nitride waveguide na dope silicon waveguide. Hejuru, uhereye ibumoso ugana iburyo, ni modulators ya depletion, Photodetector ya germanium, na germaniumibyuma byongera imbaraga.

Igishushanyo 2: Kwambukiranya igice cya silikoni ishingiye kuri optique ya waveguide ikurikirana, yerekana igihombo gikwirakwizwa no kwerekana ibimenyetso.
