Isifinyezo sesidingo se-I-laser ye-DFB
（1） Umqondo oyinhloko we-laser ye-DFB
I-laser eqhubekayo ye-DFB, eyaziwa nangokuthi impendulo eqhubekayo esakazwa ngamagagasii-laser ye-semiconductor, ihlanganisa isakhiwo se-grating esiqhubekayo esifundeni se-active waveguide se-laser. Ngokuncika kumphumela wempendulo esabalele we-grating, i-frequency selective resonance iyafinyelelwa, futhi i-laser ikhishwa ngendlela eqhubekayo nengaphazanyiswa yesimo esizinzile kuyo yonke inqubo, ngaphandle kokuphazamiseka kwe-pulse noma ukuguquguquka kwamandla.
Uma kuqhathaniswa nama-laser avamile e-FP nama-laser e-DFB aqhutshwayo, izinzuzo zayo eziyinhloko zivelele kakhulu: okokuqala, inamandla amakhulu okuqina kobude bewavelength, ingafinyelela umphumela oqondile wobubanzi bomugqa, futhi inokumelana okuhle kakhulu nokuphazamiseka kokushisa kwemvelo kanye nokudlidliza; Okwesibili, amandla okukhipha ayaqhubeka futhi azinzile, anekhwalithi ephezulu kanye nomsindo ophansi kakhulu; Okwesithathu, inokuhambisana okuhle, i-bandwidth enkulu yokuguquguquka, futhi ifanelekela izigcawu ezahlukahlukene ze-optoelectronic ezinamabanga amade, ukunemba okuphezulu, kanye nokuqina okuphezulu. Ngokusekelwe kokungafani kwezimpawu, ama-laser e-DFB aqhutshwayo avame ukusetshenziswa ekuxhumaneni kwe-rangi kanye ne-pulse, kuyilapho ama-laser aqhubekayo e-DFB egxila ezimweni zohlelo lokusebenza oluzinzile olusezingeni eliphezulu, ngezithiyo zobuchwepheshe eziphakeme kanye nenani elengeziwe lomkhiqizo.
(2) Isizinda sesidingo semboni
1. Ukuphindaphinda okusheshayo kokuxhumana kwe-optical kudale izidingo eziphuthumayo
Inethiwekhi yamandla okusebenza kwekhompyutha yomhlaba wonke, iziteshi zesisekelo ze-5G/6G, izikhungo zedatha, kanye namanethiwekhi omgogodla athuthukela kumazinga esivinini aphezulu kakhulu angu-200G/400G/800G. Ama-laser endabuko awakwazi ukuhlangabezana nezidingo zokudluliselwa kwebanga elide kanye nezinga eliphansi lamaphutha. Ama-laser aqhubekayo e-DFB, njengomthombo wokukhanya oyinhloko wamamojula we-optical wesivinini esikhulu, ayizingxenye eziyisisekelo zokusebenza okuzinzile kwezinhlelo zokuxhumana ze-optical zesivinini esikhulu.
2. Ukushintshwa kwezinzwa zekhwalithi ephezulu eShayina kuyadingeka ngokushesha
Izinkambu zokuzwa kwe-fiber optic, ukutholwa kwegesi, i-LiDAR, ukuhlola uphethiloli, ukutholwa kokunemba kwendiza, njll. zinezidingo eziqinile zokunemba kwe-wavelength, ukuzinza, kanye nokuphila kwenkonzo ye-umthombo wokukhanya we-laserSekuyisikhathi eside, ama-laser e-DFB aqhubekayo aphezulu ethembele ekungenisweni kwempahla, futhi isidingo sasekhaya sokulawulwa okuzimele siyaqhubeka nokukhula, okuphoqa intuthuko kwezobuchwepheshe ochungechungeni lwemboni.
3. Ukwandisa ngokuqhubekayo izimo zesicelo ezivelayo
Izinkambu ezisafufusa ezifana nemithi ye-laser, ukuhlaziywa kwe-spectral enembile, ukutholwa kwezinga lokushisa elingaguquki lezimboni, kanye nokuxhumana kwe-quantum kukhula ngokushesha. Isimo esizinzile, umsindo ophansi, kanye nemithombo yokukhanya ye-laser eqhubekayo enobubanzi obuncane iye yaba yinto ejwayelekile endaweni yesehlakalo, ivula njalo isikhala esikhulayo embonini.
