Uyilo lwesekethe edityanisiweyo

Uyilo lwePhotonicisekethe elihlanganisiweyo

Isekethe ehlanganisiweyo.Ipicyenziwe ngokulandela i-paters ezininzi (ngokwesiqhelo i-10 ukuya kwi-30) kwi-wafer, edityaniswe ngeemilo ezininzi zePolygonal, zihlala zimelwe kwifomathi ye-GDSII. Ngaphambi kokuba uthumele ifayile kumvelisi wefoto, inqweneleka kakhulu ukuba ikwazi ukulinganisa i-pic ukuqinisekisa ukuchaneka koyilo. Ukufakwa kwahlulwe ngokwamanqanaba amaninzi: inqanaba eliphantsi le-Electromagner (E), apho kwenziwa i-Incroomagring (em) ye-Electromagnetic (em), apho kwenziwa i-ECRAMAGATRE ye-ENCONICTIC, apho kwenziwa khona kwinqanaba le-cavelongl yangaphantsi, nangona unxibelelwano phakathi kweeatom ezikwi-Macroscopic. Iindlela eziqhelekileyo ziquka umahluko wexesha le-Dime-Demating-ye-DDTD (3D FDTD) kunye nolwando lwe-eigenmode (i-EGE). Ezi ndlela zichanekile kakhulu, kodwa azinantsingiselo kuyo yonke ixesha lemifanekiso ye-pic. Inqanaba elilandelayo li-2,5-dimestralsm yokulinganisa, njengokusasazeka okuphezulu kwe-beam (i-FD-BPM). Ezi ndlela zikhawuleza kakhulu, kodwa zidiniwe ngokuchanekileyo kwaye zinokuphatha ukusasaza iparaxial kwaye ayinakusetyenziselwa ukuhlengahlengisa abathengisi, umzekelo. Inqanaba elilandelayo li-2D ISimozulu, njenge-2D fdtd kunye ne-2D BPM. Oku kuyakhawuleza, kodwa kungasebenzi kakuhle, njengoko bengakwazi ukwenza i-rotator yokulinganisa. Inqanaba elinye lisasazekile kwaye / okanye lisasaze i-matrix ye-matrix. Each major component is reduced to a component with input and output, and the connected waveguide is reduced to a phase shift and attenuation element. Ezi fowuni zikhawuleza kakhulu. Umqondiso wokukhupha ufunyanwa ngokuphindaphindwanga i-matrix yosulelo nge-IPTAL. I-Matrix esasaziweyo (izinto zakhe ezibizwa ngokuba yi-S-Parameters) iphinda-phinda imiqondiso kunye nemiqondiso yemveliso kwelinye icala ukufumana imiqondiso yegalelo kunye nemveliso kwelinye icala lecandelo. Ngokusisiseko, i-scateting matrix iqulethe umboniso ngaphakathi kwinto ethile. I-scateting matrix ihlala iphindwe kabini njenge-matrix yodluliselo kwi-matriment yodluliselo. Kwisishwankathelo, ukusuka kwi-3D e-Em ukuya kwi-Matrix yeMatrix, umaleko ngamnye wokulinganisa unikezela ngenqanaba lokurhweba kunye nokuchaneka, kunye nabayili, kunye nabayili bakhetha ilungelo lokwenza iimfuno zenjongo yazo.

Nangona kunjalo, ukuthembela kwi-elektromagnetic ukulinganisa kwezinto ezithile kwaye kusetyenziswe i-Matrix / ye-Matrix yokusasaza ukulinganisa yonke ipini ayiqinisekisi uyilo oluchanekileyo oluphambili kwiplate yokuhamba. Umzekelo, ubude bendlela ephosakeleyo, i-multimode wavegagides eshukumayo ukunyanzela iindlela eziphezulu zoku-odola, okanye ezimbini wavavave ezikufutshane kakhulu ukuba ziphikiswe kwiingxaki ezingalindelekanga zinokuya kungabonakali ngexesha lokulinganisa. Ke ngoko, nangona izixhobo zokwenza izinto eziphezulu ze-SICORD zibonelela ngamandla asebenzayo of Reflootion, isafunwa ngokuphambili komyili kunye nokuhlolwa kwamava oncedo kunye nolwazi lobuchwephesha, ukuqinisekisa ukuchaneka kwephepha lokuhamba.

Indlela ebizwa ngokuba yi-Sparse FDTD ivumela i-3D kunye ne-2D ye-FDTD ye-FDTD yenziwa ngokuthe ngqo kuyilo olupheleleyo lokuqinisekisa uyilo. Nangona kunzima nakwesiphi na isixhobo sokwazisa i-electromagnetic ukulinganisa i-pic enkulu kakhulu yepikthi, i-spars ikwazi ukulinganisa indawo enkulu yasekhaya. Kwi-CDTD yendabuko ye-3D, i-stimation iqala ngokuqalisa izinto ezintandathu zentsimi ye-elektromagnetic ngaphakathi kwevolumu ethile ekhethekileyo. Njengoko ixesha liqhubeka, icandelo lentsimi elitsha kwivolumu ibalwa, njalo njalo. Inyathelo ngalinye lifuna ukubala, ngokufanayo kuthatha ixesha elide. Kwi-sparsse 3D fdtd, endaweni yokubala inyathelo ngalinye kwivolumu nganye, uluhlu lwamacandelo asendle lugcinwa luhambelana nevolumu enkulu kwaye ibalwe kuphela kwezo zinto zikunye nazo. Ngexesha ngalinye inyathelo, amanqaku ahambelana namacandelo asentsimini ayongezwa, ngelixa amacandelo asentsimini aphantsi komqobo othile. Kwezinye iindawo, le nguqu inokuba zii-odolo ezininzi zobukhulu ngokukhawuleza kune-3D ye-3D fdtd. Nangona kunjalo, i-sparte fdtd ayisebenzi kakuhle xa ujongene nezakhono zokusasazeka kuba eli ntsimi isasazeka kakhulu, ikhokelela kuluhlu olude kakhulu kwaye kunzima ukuphatha. Umzobo 1 ubonakalisa umzekelo we-screnshinit ye-3D fdtd ye-STDTD efana ne-bolarization beam splitter (PBs).

Umzobo 1: Iziphumo zokuSebenza ezivela kwi-3D sparse fdtd. . . Imizobo emibini engentla ibonisa umbono ophezulu we-quasi-te kunye ne-quasi-tem, kunye nemizobo emibini ngezantsi bonisa umbono ofanelekileyo wecandelo. .
