Igenzura rya polarisiyumu electro-optique igerwaho na femtosekond laser yanditse hamwe na kristu ihindagurika

Polarisiyasi electro-optiquekugenzura bigerwaho na femtosekond laser yanditse hamwe na kristu ya moderi

Abashakashatsi bo mu Budage bakoze uburyo bushya bwo kugenzura ibimenyetso bya optique bahuza inyandiko ya femtosekond laser na kristu y'amaziamashanyarazi ya optique. Mugushira mumazi ya kirisitiya mumashanyarazi, kugenzura amashanyarazi ya optique ya beam polarisiyasi iragaragara. Ikoranabuhanga rifungura uburyo bushya bushoboka kubikoresho bishingiye kuri chip hamwe na sisitemu ya fotonike ikora ikoresheje tekinoroji yo kwandika femtosekond. Itsinda ry’ubushakashatsi ryasobanuye uburyo bakoze amasahani ashobora guhinduka mumashanyarazi ya silicon yahujwe. Iyo umuyagankuba ushyizwe kumazi ya kirisiti, molekile ya kirisiti ya kirisiti irazunguruka, igahindura imiterere ya polarisiyasi yumucyo woherejwe mumuraba. Mu bushakashatsi bwakozwe, abashakashatsi bahinduye neza polarisiyasi yumucyo kuburebure bubiri butandukanye (Ishusho 1).

Gukomatanya tekinoroji ebyiri zingenzi kugirango ugere ku majyambere mashya mubikoresho bya 3D fotonike
Ubushobozi bwa lazeri ya femtosekond kugirango yandike neza umurongo wimbere imbere yibikoresho, aho kuba hejuru gusa, bituma bakora tekinoroji itanga ikizere cyo kugwiza umubare wumurongo wa chip kuri chip imwe. Ikoranabuhanga rikora mukwibanda cyane kumurongo wa laser imbere yibikoresho bibonerana. Iyo ubukana bwurumuri bugeze kurwego runaka, urumuri ruhindura imiterere yibintu aho rukoreshwa, nkikaramu ifite micron neza.
Itsinda ry’ubushakashatsi ryahurije hamwe uburyo bubiri bwibanze bwa fotone kugirango bashiremo urwego rwa kirisiti ya flux muri fluxide. Mugihe urumuri rugenda runyura mumurongo wamazi kandi unyuze mumazi ya kirisiti, icyiciro hamwe na polarisiyasi yibiti bihinduka umurima wamashanyarazi. Ibikurikira, urumuri rwahinduwe ruzakomeza gukwirakwira mugice cya kabiri cyumurongo woguide, bityo bigerweho no kohereza ibimenyetso bya optique hamwe nibiranga modulation. Ubu buhanga bwa Hybrid bukomatanya tekinoroji zombi butuma ibyiza byombi haba mugikoresho kimwe: kuruhande rumwe, ubwinshi bwumucyo mwinshi wazanywe ningaruka ya waveguide, kurundi ruhande, ihinduka ryinshi rya kirisiti y'amazi. Ubu bushakashatsi bufungura uburyo bushya bwo gukoresha imiterere ya kristu ya kirisiti kugirango ushiremo umurongo wogukoresha mubunini bwibikoresho nkabayoboraKuriibikoresho bya fotonike.

Igicapo 1 Abashakashatsi bashizemo ibice byamazi ya kirisiti mumashanyarazi yakozwe na laser itaziguye, kandi ibikoresho bivangavanze bishobora gukoreshwa muguhindura polarisiyasi yumucyo inyura kumurongo.

Gushyira hamwe nibyiza bya kirisiti muma femtosekond laser waveguide modulation
NubwoGuhinduramuri femtosekond laser yandika umurongo wogusohora mbere byagezweho cyane cyane mugukoresha ubushyuhe bwaho kumurongo wogukoresha, murubu bushakashatsi, polarisiyasi yagenzurwaga no gukoresha kristu y'amazi. Abashakashatsi bagize bati: "Uburyo bwacu bufite inyungu nyinshi zishoboka: gukoresha ingufu nke, ubushobozi bwo gutunganya umurongo wigenga wigenga, no kugabanya kwivanga hagati y’imiyoboro yegeranye". Kugirango bagerageze gukora neza igikoresho, itsinda ryinjije lazeri mumurongo woguhindura kandi uhindura urumuri muguhindura voltage ikoreshwa kumurongo wa kirisiti. Impinduka za polarisiyonike zagaragaye ku bisohoka zirahuye n'ibiteganijwe. Abashakashatsi basanze kandi ko nyuma ya kirisiti y’amazi imaze guhuzwa na fluxide, ibiranga modulisiyo ya kirisiti y’amazi ntibyigeze bihinduka. Abashakashatsi bashimangira ko ubushakashatsi ari gihamya gusa, bityo haracyari byinshi byo gukora mbere yuko ikoranabuhanga rishobora gukoreshwa mubikorwa. Kurugero, ibikoresho bigezweho bihindura imirongo yose muburyo bumwe, itsinda rero ririmo gukora kugirango ryigenzure ryigenga rya buri cyerekezo cyihariye.
