Cov khoom siv sib txuas lus optical

Cov qauv ntawmcov khoom siv sib txuas lus kho qhov muag

Lub kaw lus sib txuas lus nrog lub teeb nthwv dej ua lub teeb liab thiab Optical fiber ua lub nruab nrab xa xov hu ua Optical fiber communications system. Qhov zoo ntawm kev sib txuas lus optical fiber piv rau kev sib txuas lus cable thiab wireless yog: muaj peev xwm sib txuas lus loj, poob qis, muaj peev xwm tiv thaiv electromagnetic cuam tshuam, muaj kev ceev ntiag tug, thiab cov khoom siv raw ntawm optical fiber kis tau yog silicon dioxide nrog kev cia khoom ntau. Tsis tas li ntawd, optical fiber muaj qhov zoo ntawm qhov me me, lub teeb yuag thiab tus nqi qis piv rau cable.
Daim duab hauv qab no qhia txog cov khoom ntawm lub voj voog photonic integrated yooj yim:laser, siv cov khoom siv kho qhov muag thiab demultiplexing,lub tshuab ntes duabthiabtus neeg hloov kho.

Cov qauv yooj yim ntawm kev sib txuas lus bidirectional fiber optical muaj xws li: hluav taws xob transmitter, optical transmitter, kis fiber, optical receiver thiab hluav taws xob receiver.
Lub teeb liab hluav taws xob ceev ceev yog encoded los ntawm lub tshuab hluav taws xob xa mus rau lub tshuab xa hluav taws xob, hloov mus rau hauv cov teeb liab teeb liab los ntawm cov khoom siv hluav taws xob xws li Laser device (LD), thiab tom qab ntawd txuas nrog lub fiber kis.
Tom qab kev xa mus ntev ntawm cov teeb liab kho qhov muag los ntawm ib hom fiber, erbium-doped fiber amplifier tuaj yeem siv los ua kom lub teeb liab kho qhov muag loj dua thiab txuas ntxiv kev xa mus. Tom qab qhov kawg ntawm kev txais teeb liab kho qhov muag, lub teeb liab kho qhov muag raug hloov mus ua lub teeb liab hluav taws xob los ntawm PD thiab lwm yam khoom siv, thiab lub teeb liab tau txais los ntawm lub tshuab txais hluav taws xob los ntawm kev ua tiav hluav taws xob tom qab. Cov txheej txheem ntawm kev xa thiab txais cov teeb liab hauv qhov kev taw qhia rov qab yog tib yam.
Yuav kom ua tiav qhov kev teeb tsa ntawm cov khoom siv hauv qhov txuas, lub tshuab xa khoom siv kho qhov muag thiab lub tshuab txais khoom siv kho qhov muag hauv tib qho chaw maj mam koom ua ke rau hauv lub tshuab xa khoom siv kho qhov muag.
Qhov ceev ceevCov khoom siv kho qhov muagyog tsim los ntawm Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) uas sawv cev los ntawm cov khoom siv kho qhov muag nquag, cov khoom siv passive, cov voj voog ua haujlwm thiab cov khoom siv photoelectric interface tau ntim. ROSA thiab TOSA tau ntim los ntawm lasers, photodetectors, thiab lwm yam hauv daim ntawv ntawm cov chips kho qhov muag.

Nyob rau hauv lub ntsej muag ntawm lub cev bottleneck thiab kev cov nyom kev siv tshuab uas ntsib hauv kev txhim kho microelectronics technology, tib neeg pib siv photons ua cov ntaub ntawv nqa khoom kom ua tiav bandwidth ntau dua, ceev dua, siv hluav taws xob tsawg dua, thiab qeeb dua photonic inteated circuit (PIC). Lub hom phiaj tseem ceeb ntawm photonic integrated loop yog kom paub txog kev koom ua ke ntawm lub teeb ci, kev sib txuas, kev hloov kho, kev lim dej, kev sib kis, kev tshawb pom thiab lwm yam. Lub zog tsav tsheb pib ntawm photonic integrated circuits los ntawm kev sib txuas lus cov ntaub ntawv, thiab tom qab ntawd nws tau tsim kho zoo heev hauv microwave photonics, quantum information processing, nonlinear optics, sensors, lidar thiab lwm yam teb.
