Silicon fonesics passive

Filikonibice bya passive

Hariho ibintu byinshi byingenzi bya pasika muri Phosickeli Silicon. Kimwe muri ibyo ni ugufata hejuru, nkuko bigaragara ku gishushanyo cya 1a. Igizwe no gukomera gukomeye mumurongo wa Waveguide ufite umwanya uhwanye nuburebure bwumucyo wumucyo muri Wavegaide. Ibi bituma urumuri rusohoka cyangwa rwakiriwe kuri perpendicular hejuru, bigatuma ari byiza kubipimo byo murwego rwo hejuru na / cyangwa guhuza kuri fibre. Gufata abashakanye ni bimwe bidasanzwe kuri photonique ya silikoni muri silicon muribo bakeneye itandukaniro rikomeye rifite ishingiro. Kurugero, niba ugerageza gukora ibihuha mu buryo busanzwe bwo guhagarika umuyaga, urumuri rumenetse mu nsinge aho gusohoka mu buryo buhagaritse kubera ko bafata urugero rwo hasi rufite uruhara. Kugirango bikore muri IDP, ibikoresho bigomba gucukurwa munsi yo gushakira kugirango uhagarike, nkuko bigaragara ku gishushanyo cya 1b.

Igicapo 1: hejuru-gusohora amafaranga umwe-ufata amafaranga muri silicon (a) na inp (b). Muri (a), imvi kandi urumuri rwubururu ruhagararire Silicon na Silica,. Muri (b), umutuku na orange uhagarariye ingwaasp na inp, kimwe. Imibare (c) na (d) gusikana microscope ya electron (sem) amashusho yinp yahagaritswe cantilever ifata counterr.

Ikindi kintu cyingenzi ni ahantu hahinduka (SSC) hagati yaoptique waveguideKandi fibre, ihindura uburyo bugera kuri 0.5 × 1 μm2 wa Waveguide ya Silicon muburyo bwa 10 × 10 μm2 muri fibre. Uburyo busanzwe nugukoresha imiterere yitwa taper insinga, aho umugozi wa Wavegude wa buhoro buhoro buhoro buhoro, bikavamo kwaguka kwinshi kwaoptiqueMode. Ubu buryo burashobora gufatwa na WaveGuide yahagaritswe, nkuko bigaragara ku gishushanyo cya 2. Hamwe na SSC nka SSC, igihombo kibujijwe kirenze 1.5DB cyagezweho byoroshye.

Igishushanyo cya 2: Ingano yubunini ihinduka kuri Silicon Wire Waveguide. Ibikoresho bya silicon bigize imiterere itandukanye imbere yikirahure wahagaritswe. Silicon substrate yarumiwe munsi yikirahure cyahagaritswe.

Ibice byingenzi byingenzi ni polarisation beam spotter. Ingero zimwe zumusozo zisorekanwa zerekanwa ku gishushanyo cya 3. Iya mbere ni intangarugero ya mach-zender, aho buri kuboko rifite uburenganzira butandukanye. Iya kabiri ni icyerekezo cyoroshye. Imiterere yimbere ya shitique isanzwe ya silicon ni ndende cyane, bityo rero umucyo wa magnetic (tm) umucyo urashobora guhuzwa kwuzuye, mugihe uhinduranya amashanyarazi (te) umucyo wa polarize urashobora gukundwa. Iya gatatu ni ugufata couponr, aho fibre ishyizwe kumurongo kugirango tele yijimye ifatanye mu cyerekezo kimwe na TM itara rya TM rikunzwe mu rundi. Iya kane ni ugufata ibice bibiri. Uburyo bwa fibre bwerekana amashanyarazi ari perpendicular yerekeza mubuyobozi bwa WaveGguide bujyanye na WaveGuide ya WaveGuide. Fibre irashobora kugabanywa no guhuzwa kugeza kuri waveguide ebyiri, cyangwa perpendicular hejuru kandi hamwe na waveguide enye. Inyungu yongeweho yo gufata ingamba ebyiri ni uko bakora nk'agateganyo ihindagurika, bivuze ko urumuri rwose kuri Chip rufite polarisation imwe, ariko urumuri rwa orthogonal rukoreshwa muri fibre.

Igicapo 3: Gutandukana Byinshi.
