Chirongwa chekutenderera nguva yekufambisa kubva paneMZM Modulator
Iyo Optical Frequency Kupararira inogona kushandiswa sechiputiTsime RenjeKufanana panguva imwe chete uye scan munzira dzakasiyana, uye inogona kushandiswawo seyakawoneka Kazhinji, iyo yakawanda-wavelength mwenje sosi inogona kunge yakaderera simba kana isina kunyatsoiswa, uye kune matambudziko mazhinji. Huroyi yakaunzwa nhasi ine zvakawanda zvakanakira uye zvinogona kutaurwa nezvenongedzo. Dhigi rayo rekugadzira rinoratidzwa seinotevera: Iyo Yakakwirira-SimbaDfb laserChiedza sosi ndeye CW mwenje mune nguva domain uye imwe chete wavelength mukuwanda. Mushure mekupfuura nepakati aModulatorNeimwe modulation frequency frequency frf, sideband ichaburitswa, uye chikamu chebhokisi chikamu chakasungirirwa frequency frf. Iyo modulator inoshandisa lnoi modulator ine kureba kwe8,2mm, sezvakaratidzwa mumufananidzo b. Mushure mechikamu chakareba chesimba rakakwirira-simbaPhase Modulator. Iyo dc bias uye kusekwa kudzika kwemodulator kunogona kukanganisa iyo flatness yeiyo Optical Frepertency kupararira.
Mathematic, chiratidzo mushure mekunge iyo yechiedza munda ichishandurwa neModulator ndeye:
Zvinogona kuoneka kuti iyo yekubuda mumunda wechiitiko ndeyekupedzisira kupararira neye frequency yekupararira kweiyo wrf, uye kusimba kweyekupedzisira nguva yekuparadzira mazino ane hukama neiyo DFB Optical Simba. Nekuenzanisa chiedza chakanyanya kupfuura kuburikidza neMZM modulator uyePm phase modulator, uyezve FFT, iyo Optical Frequency Kupararira Spectrum inowanikwa. Mufananidzo uyu unotevera unoratidza hukama hwakananga pakati pepfungwa yekufambisa uye modulator dc bias uye modulation yakadzika pane iyi simulation.
Mufananidzo uyu unotevera unoratidza sportreral spectral dagram ine mm bias dc ye 0.6,0
Iyi inotevera ndiyo dhizaini yeMZM modulator, ln is 500nm gobvu, kudzika kwegadziriro ndeye 260nm, uye iyo Wedzera Walkth ndeye 1.5um. Iko ukobvu hwegoridhe reElectrode ndeye 1.2m. Iko ukobvu kweiyo yepamusoro cladding Sio2 ndeye 2um.
Izvi zvinotevera ndeyekuonekwa kweiyo yakaedzwa yeCC, ine gumi nematanhatu emazino mazino uye flatness <2.4DB. Iyo modulation frequency ndeye 5GHZ, uye iyo RF Simba Kuisa MZM uye PM ndeye 11.24 DBM uye 24.96DBM zvichiteerana. Huwandu hwemeno emazino ekupedzisira kupararira kufarirwa kunogona kuwedzera simba rekuwedzera iyo PM-RF Simba rePM-RF mufananidzo
Izvo zviri pamusoro zvinoenderana neLnoi chirongwa, uye zvinotevera zvinobva muIVIV chirongwa. Dhijaho reruzivo ruri seinotevera: Iyo chip inobatanidza dBr larser, mzm modulator, pm phose modulator, soa uye ssc. Chipo chimwe chete chinogona kuwana yakakwira performation Optical frequency kuderera.
Iyo SMSR yeDBR LASER ndeye 35DB, iyo Line Bidth is 38mhz, uye huwandu hwekutonga ndi9nm.
Iyo MZM modulator inoshandiswa kugadzira sideband nehurefu hwe 1mm uye bandwidth yegumi nenomwe 7GH. Inonyanya kushoma nekukanganiswa mismpatch, Optical kurasikirwa kusvika 20db @ -8b bias
Kureba kweSOA ndeye 500μm, iyo inoshandiswa kudzorera iyo modulation Optical Kusiyana kurasikirwa, uye iyo spectral bandwidth is 62nm @ 3dc @ 90m. Iyo yakabatanidzwa SSC pane iyo inobuda inovandudza iyo coupling yekudyara kweiyo chip (coupling yekubudirira ndeye 5DB). Simba rekupedzisira rekubuda riri pamusoro -7dbm.
Kuti uburitse Optical Frequency Kupararira, iyo RF modulation frequency inoshandiswa ndeye 2.6GHz, simba riri 24.7Dbm, uye iyo VPI yePPI yePHEO modlator ndeye 5V. Iyo nhamba iri pazasi ndiyo inokonzerwa nefoni photoshobic spectrum ine 17 photosphic meno @ 10DB uye SNSR yakakwirira kupfuura 30db.
Iyo Scheme yakagadzirirwa 5G microwave kutapurirana, uye inotevera chiumbwa chidimbu chidimbu chinowanikwa neyechiedza cheki, chinogona kuunza 26g signals ne10 times kuwanda. Hazvitaurwe pano.
Mukupfupikisa, kuwanda kwechiitiko kunogadzirwa nenzira iyi kune yakagadzikana frequency kupindirana, ruzha rwakatsetseka, simba rakakwirira uye kusanganisa nyore, asi kune mamwe matambudziko akati wandei. Iyo RF chiratidzo chakaremerwa pane iyo PM inoda simba rakakura, kupindirwa kwakakura kwesimba, uye nguva yekuwedzera inogumira neyekufambisa chiyero, anosvika 50ghz, anowanzo batanidza nguva (kazhinji> 10nm) muFr8 system. Kushandiswa kushoma, kubhururuka kwemagetsi hakusi kukwana.
