Hauv kev sib txuas lus kho qhov muag fiber ntau, laser diodes hauv 1310nm thiab 1550nm bands tau dav siv vim lawv cov yam ntxwv tshwj xeeb. Ob pawg no nyob rau hauv cheeb tsam ze-infrared, muaj lawv tus kheej zoo thiab cov kev txwv, thiab tseem ceeb heev rau kev sib txuas lus sib txawv thiab cov kev xav tau.

Cov yam ntxwv thiab qhov tseem ceeb ntawm 1310nm band:
Tsawg-tsawg kis tau tus mob: Lub 1310nm band muaj kuj tsis tshua muaj attenuation nyob rau hauv tus qauv ib hom fiber ntau (SMF). Txawm hais tias nws tsis yog qhov poob qis tshaj plaws ntawm cov fiber ntau, qhov kev sib kis tau zoo ntawm cov teeb liab tseem tuaj yeem ua tiav.
Nqi-Effectiveness: 1310nm laser diodes thiab lwm yam khoom siv feem ntau tsis tshua kim tshaj li cov khoom siv hauv 1550nm band, ua rau lawv zoo nkauj dua hauv cov nqi siv hluav taws xob.
Kev cuam tshuam ntawm dispersion: Piv nrog 1550nm band, 1310nm muaj qis dispersion nyob rau hauv tus qauv ib hom fiber ntau, uas yuav pab txo cov teeb liab distortion teeb meem nyob rau hauv kev sib kis mus ntev.
Daim ntawv thov muaj peev xwm: 1310nm band feem ntau yog siv rau kev nkag mus rau hauv tes hauj lwm, hauv cheeb tsam network (LAN) thiab cheeb tsam cheeb tsam network (MAN), nrog rau luv mus rau nruab nrab cov ntaub ntawv kis tau tus mob scenarios.
Cov yam ntxwv thiab qhov tseem ceeb ntawm 1550nm band:
Qhov qhov poob qis kawg nkaus: 1550nm band nyob rau hauv qhov poob qis tshaj plaws ntawm quartz fiber, tseem hu ua C-band (1530nm txog 1565nm), muab qhov zoo tshaj plaws attenuation kev ua tau zoo rau kev sib kis mus ntev.
Kev xa mus ntev: Vim nws cov yam ntxwv tsis tshua muaj nyob hauv cov khoom siv kho qhov muag, 1550nm band yog tshwj xeeb tshaj yog haum rau kev sib txuas lus ntev, kev kub ceev kho qhov muag fiber ntau, xws li lub teb chaws qaum tes hauj lwm thiab submarine optical cables.
Dispersion tswj: 1550nm band ntsib teeb meem dispersion ntau dua nyob rau hauv ib hom fiber ntau, tshwj xeeb tshaj yog piv rau 1310nm. Yog li ntawd, dispersion them nyiaj siv tshuab yuav tsum tau ua kom muaj teeb meem zoo.
Optimized rau wavelength division multiplexing: Vim nws qhov tsis tshua muaj qhov tsis zoo, 1550nm band yog qhov tsim nyog rau wavelength division multiplexing (WDM) technology, uas tuaj yeem xa cov teeb liab ntawm ntau lub wavelengths ntawm ib qho khoom siv fiber ntau, ua rau cov ntaub ntawv xa mus ntawm fiber ntau optical fibers. . muaj peev xwm.
Niaj hnub nimno kev sib txuas lus infrastructure: 1550nm band yog ib qho tseem ceeb rau kev ua tiav high-bandwidth, high-data-rate niaj hnub kev sib txuas lus infrastructure thiab yog ib tug tseem ceeb technology rau 4G thiab 5G mobile kev sib txuas lus, data center interconnection thiab high-ceev Internet kev pab cuam.

Nrog rau kev txhim kho thev naus laus zis thiab kev txhim kho cov kev xav tau ntawm kev sib txuas lus, qhov kev thov rau laser diodes nyob rau hauv ob pawg no txuas ntxiv loj hlob, ua rau lawv txoj hauj lwm hauv kev sib txuas lus fiber ntau yog qhov tseem ceeb.1310nm 1550nm Dual Wavelength FP Fiber Pigtail Laser Diodeyog lub laser muaj peev xwm ntawm emitting ob lub wavelengths tshwj xeeb (1310nm thiab 1550nm). Nws txoj hauv kev siv tshuab suav nrog kev kho qhov muag thiab hluav taws xob engineering.

Ua ntej, txoj cai ua haujlwm ntawm dual-wavelength emission yog raws li cov yam ntxwv ntawm laser diodes (LD). Nyob rau hauv ib tug raug laser diode, thaum lub PN hlws ris yog rau pem hauv ntej biased los ntawm ib tug sab nraud voltage qhov chaw, electrons hla lub hlws ris thiab recombine nrog qhov, tso photons. Cov photons tom qab ntawd ntaus lwm cov atoms, ua rau kev tso tawm ntau dua photons, tsim kom muaj kev cuam tshuam avalanche. Los ntawm kev tsim qauv tsim qauv, lub wavelength ntawm emitted teeb tuaj yeem tswj tau.

Qhov thib ob, txhawm rau txhawm rau ua tiav kev hloov pauv ntawm lub wavelengths ntawm 1310nm thiab 1550nm, lub hauv paus ntsiab lus ntawm Fabry-Pérot (FP) kab noj hniav feem ntau yog siv los xaiv thiab nthuav dav lub teeb ntawm cov wavelengths tshwj xeeb. Lub FP kab noj hniav nyob rau hauv no laser yog tsim los ntawm ob feem ntawm daim iav. Qhov kev ncua deb ntawm lawv txiav txim siab lub resonant zaus ntawm kab noj hniav, uas yog, qhov tshwj xeeb wavelength ntawm lub teeb emitted. Los ntawm kev hloov pauv qhov kev txhaj tshuaj tam sim no lossis qhov kub thiab txias, qhov ntsuas qhov cuam tshuam ntawm cov kab noj hniav tuaj yeem hloov pauv, yog li hloov qhov sib txawv wavelength outputs. Tsis tas li ntawd, kev siv fiber ntau Bragg gratings (FBG) kuj yog ib txoj hauv kev los xaiv cov wavelengths vim FBGs muaj peev xwm cuam tshuam cov wavelengths ntawm lub teeb thiab xa mus rau lwm cov wavelengths, yog li tsim ib qho kev ruaj khov resonant hom nyob rau hauv lub laser.

Thaum kawg, pigtail thev naus laus zis hais txog kev sib txuas cov zis ntawm lub laser diode rau hauv fiber ntau optical. Qhov zoo ntawm kev ua li ntawd suav nrog lub teeb kis tau yooj yim, txhim kho beam zoo, thiab ntau dua qhov system stability. Lub teeb emissions los ntawm fiber-coupled laser diodes muaj ib ncig thiab du siv tis thiab ib tug symmetrical beam, uas yog heev pab tau rau kev txhim kho coupling efficiency thiab txo qhov poob.

Hauv cov ntsiab lus, lub dual-wavelength FP fiber ntau pigtailed laser diode sib txuas cov wavelength selectivity thiab resonance yam ntxwv ntawm FP kab noj hniav nrog rau kev yooj yim ntawm pigtail technology nyob rau hauv cov nqe lus ntawm beam zoo thiab kis tau tus mob, ua kom tiav ob lub qhov rais kev sib txuas lus tseem ceeb -1310nm thiab 1550nm. -High efficiency thiab ruaj khov tso zis. Cov yam ntxwv no ua rau nws muaj kev thov dav dav hauv kev sib txuas lus kho qhov muag fiber ntau niaj hnub.

Dual-wavelength FP fiber ntau pigtail laser diodes tau siv dav hauv kev sib txuas lus niaj hnub thiab kuj tau pom muaj peev xwm zoo hauv ntau qhov chaw.
