Dhizaini yePhotonicYakabatanidzwa Circuit
Photonic yakabatanidzwa zvapera.PicYakagadzirwa nekuparadzira akawanda marongero (kazhinji 10 kusvika 30) pachigadzirwa, izvo zvinoumbwa nemhando dzakawanda dzePolygonal, kazhinji inomiririrwa muGWDII FOMT. Usati watumira iyo faira kune iyo Photomask mugadziri, inodikanwa kwazvo kuti ikwanise kutevedzera iyo pikicha kuti uone kuti kurongeka kwekugadzira. Kufungidzira kwakakamurwa kuita huwandu hwakawanda Typical Nzira dzinosanganisira matatu-Dimensional Finite-Musvitsvina Nguva-Domain (3D FDTD) uye EigenMODE KUFANIRA (Eme). Idzi nzira dzakanyatsonaka, asi dzisingabatsiri dzeiyo nguva yese yekufungidzira nguva. Chikamu chinotevera chiri 2,5-dimensional em simplation, yakadai seyinonyadza-mhere-mhere nhema nhema (FD-BPM). Nzira idzi dzinokurumidza kwazvo, asi tibayire kumwe kurongeka uye kunogona kungobata zvimisikidzo zvembambo uye hazvigone kushandiswa kutevedzera veronators, semuenzaniso. Chikamu chinotevera chiri 2D em simulation, yakadai se 2D FDTD uye 2D BPM. Izvi zvinokurumidza zvakare, asi kuve nekushanda shoma, sekuti ivo vasingakwanise kutevedzera polarization rotates. Imwe nhanho iri kutapurirana uye / kana kuparadzira matrix simulation. Chikamu chimwe nechimwe chikuru chinoderedzwa kusvika kune chimwe chinhu chine chekuita uye kubuda, uye chakabatana waveguide chakaderedzwa kusvika kune chikamu chekuchinja uye chinosimbisa chinhu. Izvi zvinonyadzisa zvakanyanyisa kukurumidza. Iyo yekubuditsa chiratidzo inowanikwa nekuwedzera iyo transmisments matrix neyekuisa chiratidzo. Iyo yekuparadzira matrix (ayo zvinhu zvinonzi S-paramende) anowedzera zviratidzo zvekuisa uye zvinobuda kune rumwe rutivi kuti uwane masaini ekuisa uye kunze kweimwe chikamu chechikamu. Chaizvoizvo, iyo inopararira matrix ine kuratidzwa mukati meiyo chinhu. Iyo yekuparadzira matrix inowanzo kuve yakakora kaviri sekutapisa matrix mune yega yega dhayesi. Mukupfupikisa, kubva ku3D em kutapurirana / kuparadzira matrix kufungidzira, kusimuka kwechifananidzo kunounza kutengeserana-kubva pakati pekumhanya kwekufungidzira kune yavo chaiyo inoda kugadzirira dhizaini yekugadzira.
Nekudaro, uchivimba neElectromagnic Sudziro yezvimwe zvinhu uye kushandisa iyo inopararira / kuendesa matrix kutevedzera iyo yese pikicha haina kuvimbisa chimiro chakakwana pamberi penzvimbo yekuyerera. Semuenzaniso, nzira dzisina kujairika dzakareba, multimode waveguides inotadza kunyatso kudzvanya nzira dzakakwirira, kana maviri ascgudes ari padyo nekutungamira kumatambudziko asingatarisirwi anogona kuenda kusingabvumirwe panguva yekufungidzira. Naizvozvo, kunyangwe zvishandiso zvepamhepo zvinopa simba zvinopa simba rekugadzira
Nyanzvi inonzi Sparse FDTD Inotendera 3D uye 2D FDTD Simple Kuti iitwe zvakananga pane yakakwana pikicha dhizaini yekusimbisa dhizaini. Kunyangwe zvakaoma chero electromagnetic Simulation chishandiso chekutevedzera yakakura kwazvo pikicha, iyo Sparse FDTD inokwanisa kutevedzera nzvimbo yakanaka yemuno. Muchinyakare Nekufamba kwenguva, chikamu chitsva chemunda mune vhoriyamu yakaverengerwa, zvichingodaro. Nhanho yega yega inoda kuverenga kwakawanda, saka zvinotora nguva yakareba. MuSparse 3D FDTD, panzvimbo pekuverenga padanho rega rega pane imwe nguva yehuwandu hwehuwandu, rondedzero yezvikamu zvemunda zvinochengetwa kuti vanokwanisa kuenderana neyekuchinjana yakakura vhoriyamu uye kuverengerwa chete kune izvo zvikamu. Panguva imwe neimwe nhanho, mapoinzi padanho kune zvikamu zvemunda zvinowedzerwa, nepo zvikamu zvemunda pazasi peimwe chikumbaridzo chemagetsi chinodonhedzwa. Kune zvimwe zvivakwa, kuumbwa uku kunogona kuva kuraira kwakawanda kwehukuru nekukurumidza kupfuura tsika yetsika 3D FDTD. Nekudaro, sparse fdtds haizoite zvakanaka kana uchibata nekuparadzira zvimiro nekuti iyi nguva munda inopararira zvakawandisa, zvichikonzera zvinyorwa zvakanyanyisa uye zvakaoma kubata. Mufananidzo 1 unoratidza muenzaniso screenshot of a 3d fdtd simulation yakafanana nePolarization Beplitter (PBS).
Mufananidzo 1: Simulation mhinduro kubva ku3D sparse fdtd. . . Iyo miviri madhayeti ari pamusoro apa inoratidza iyo yepamusoro maonero eQuasi-te uye quasi-tm masaini, uye madhiragi maviri pazasi anoratidza kuenderana-chikamu chevhu. .
