A DFB Npauj Npaim Laser Diodeyog qhov ua tau zoo semiconductor laser qhov chaw dav siv hauv kev sib txuas lus fiber-optic
Rhuav tshem lub sij hawm:
| Lub caij | Lus piav |
|---|---|
| DFB (Tshaj Tawm Tawm tswv yim) | Ib hom laser diode nrog lub built-in diffraction grited muab wavelength-xaiv cov lus qhia, hom ntev) ua haujlwm |
| Tus npauj npaim | Hais txog cov pob txha, muaj zog, hermetically kaw pob ua ke me ntsis li npauj npaim (TEC), Phododiode, thiab Optical Fiber ntau tus npua |
Dab tsi yog DFB Npauj Npaim Laser Diode?
A Faib cov lus (DFB) Laser Diodeemits teeb nyob rau ntawm ib txoj kab uas nqaim heev (ib zaus) vim yog cov qauv sib dhos hauv sab hauv
TusNpauj Npaim Pobtiv thaiv lub cuab yeej, muab cov storilization thermal (ntawm TEC), suav nrog cov lus tawm tswv yim rau cov zis siv hluav taws xob yooj yim rau hauv cov khoom siv kho tshiab.
Feem ntau ua haujlwm hauvC-Band (~ 1550 nm)lossisL-band (~ 1310 nm)rau kev siv Telecom .
Cov Nta Tseem Ceeb
| Yam zoo | Kev piav txog |
|---|---|
| Ib qho wavelength tawm | Nqaim linewidth (~ 1 mhz lossis tsawg dua), ruaj khov rau qhov kub |
| Sib xyaw Thermoelectric txias (TEC) | Tswj hwm qhov ntsuas kub kom ceev rau nthwv dej ruaj khov |
| Saib xyuas photodiode | Tso cai rau lub sijhawm tso zis tawm hluav taws xob |
| Fiber ntau pigtail | Pre-txuas optical fiber rau yooj yim coupling |
| Hermetic Sealing | Tiv thaiv tiv thaiv noo noo thiab paug |
| Compact Loj | Txheem Npauj Npaim Daim Ntawv (~ 14- pin) |
