Kutheniiinkqubo ze-fiber optic ezinamandla aphezuluithambekele ngakumbi kwiziphumo ezingezizo ezomgca?
In iinkqubo ze-fiber optic, iingxaki ezininzi azize zenzeke phantsi kweemeko zamandla aphantsi, kodwa xa amandla enyuswa, ngequbuliso zibonakala okanye zingalawuleki, njengokwandiswa kwe-spectral, ukungazinzi kwamandla, ukuphazamiseka kwesignali, kunye nokusebenza kakuhle kwenkqubo. Ezi zinto zihlala zibangelwa ligama eliphambili: iziphumo ezingezizo emgceni. Ngoko ke umbuzo ngulo: kutheni ke xa ingena kwimeko yamandla aphezulu, iinkqubo ze-fiber optic zisengozini enkulu yeengxaki ezingezizo emgceni?
1, Izizathu ezibalulekileyo zeziphumo ezingezizo ezomgca
Izinto ze-fiber optic (i-quartz) ngokwazo zineempawu ezingezizo ezomgca, ezibonakala kakhulu njenge-refractive index etshintsha ngamandla okukhanya (isiphumo se-Kerr). Ngamandla aphantsi, esi siphumo sibuthathaka kakhulu kwaye asinamsebenzi; Kodwa xa amandla enyuka, amandla okukhanya ayanda kwaye isiphumo esingezizo ezomgca siphucuka kakhulu.
2, Izinto eziphambili zokwandisa iziphumo ezingezizo ezomgca phantsi kwamandla aphezulu
Ukukhanya okuphezulu kakhulu: Indawo ye-mode field yee-optical fibers incinci kakhulu (idla ngokuba ngamashumi e-μ m²), kwaye nokuba amandla apheleleyo akaphezulu, ukukhanya sele kuphezulu kakhulu. Iziphumo ezingezizo ezomgca zinxulumene ngokuthe ngqo nokukhanya okunamandla (endaweni yamandla apheleleyo), kwaye njengoko amandla esanda, ukukhanya kuyanda ngokukhawuleza, kwaye iziphumo ezingezizo ezomgca ziyanda ngokufanelekileyo.
Ubude bokusebenza obude: Ukukhanya kwi-optical fibers kunokwanda kangangeemitha ezininzi ukuya kwiikhilomitha ezininzi, kwaye iziphumo ezingezizo ezomgca ziyaqhubeka nokuqokelelana kuyo yonke inkqubo yokusasazeka, ekugqibeleni zibe nempembelelo ebalulekileyo. Ubunzulu beziphumo ezingezizo ezomgca bunokuqondwa njengobulingana nobunzulu bokukhanya obuphindaphindwe ngobude bokusasazwa.
3, Iziphumo eziqhelekileyo ezingezizo ezomgca kunye nokubonakaliswa kwazo
Ukuzilawula kwesigaba (i-SPM): Utshintsho kubunzulu bokukhanya lubangela utshintsho kwi-refractive index, nto leyo ebangela utshintsho lwesigaba kunye nokwandiswa kwe-spectral, nto leyo ebonakala njengokwandiswa kwe-pulse kunye nokwandiswa kwe-spectral.
I-Stimulated Brillouin Scattering (SBS): Ivuselelwa lula phantsi kobubanzi obumxinwa kunye neemeko zamandla aphezulu, kunye nomda ocacileyo onokuvelisa ukusasaza emva, unciphise amandla adlulisiweyo, kwaye ubangele ukwehla ngequbuliso okanye ukungazinzi kwimveliso yenkqubo.
I-Stimulated Raman Scattering (SRS): Ibonakala ngamandla aphezulu okanye kwiifayibha ezinde, ezibonakaliswa kukudluliselwa kwamandla ukuya kumaza amade kunye notshintsho kwisakhiwo se-spectral.
4, Isizathu sokuba ingxaki ingabonakali phantsi kwamandla aphantsi
Iziphumo ezingezizo ezilandelelanayo zineempawu zomda kunye neempawu zokukhula ezingezizo ezilandelelanayo. Isiphumo sibuthathaka kakhulu kwaye kunzima ukusiqokelela ngamandla aphantsi; Xa amandla edlula umda, isiphumo siya kwanda ngokukhawuleza size sivele ngequbuliso, nto leyo echaza imeko "yeengxaki ezibonakala ngequbuliso kwangoko nje xa amandla enyuka" kubunjineli.
5, Iingxabano eziphambili kunye neendlela zokujongana neengxaki zobunjineli
Iinkqubo zamandla aphezulu kufuneka zicinezele iziphumo ezingezizo ezomgca ngelixa zinyusa amandla. Iindlela zobunjineli eziqhelekileyo ziquka:
Ukwandisa indawo yentsimi yemowudi ukunciphisa ubukhali bokukhanya
Nciphisa ubude obusebenzayo besenzo
Yandisa ububanzi bomgca ukuze ucinezele i-SBS
Lungiselela uyilo lwenkqubo
Ingcamango esisiseko kukunciphisa amandla okukhanya ngeyunithi nganye okanye ukunciphisa iziphumo ezidibeneyo ezingezizo ezantsi.
Isiphelo
Amandla phezului-fiber opticIinkqubo zinotyekelo oluphezulu kwiziphumo ezingezizo emgceni, kwaye isizathu esiyintloko kukuba ukukhanya okuphezulu kunye nomgama omde wokusebenza kwifayibha kwandisa iimpawu ezingezizo emgceni zezinto. Iziphumo ezingezizo emgceni ziqokelelana ngamandla kunye nobude, kwaye zibonakala ngokukhawuleza emva kokudlula umda. Ke ngoko, ukulawula ukukhanya kunye nobude obusebenzayo kuyilo lwenkqubo ngundoqo ekucinezeleni ukungabikho komgca.
