Product Description
Tam sim no, feem ntau yog peb hom kev avalanche suppression rau InGaAs APDs: passive suppression, active suppression thiab gated detection. Passive suppression tsub kom lub sij hawm tuag ntawm avalanche photodiodes thiab tiag txo qhov siab tshaj plaws suav tus nqi ntawm lub ntes, thaum lub active supposedly nyuaj heev vim hais tias lub tsub zuj zuj Circuit Court yog heev nyuaj thiab lub teeb liab cascade yog nquag emission. Lub gated nrhiav hom yog tam sim no siv nyob rau hauv ib leeg-photon nrhiav kom tau. Feem ntau siv.
Ib leeg-photon nrhiav tshuab tuaj yeem txhim kho qhov tseeb thiab kev tshawb pom kev ua haujlwm ntawm lub system. Nyob rau hauv qhov chaw laser kev sib txuas lus system, qhov kev siv ntawm qhov teeb meem lub teeb teb yog heev qaug zog, yuav luag mus txog lub photon theem. Lub teeb liab pom los ntawm lub dav hlau photodetector yuav raug cuam tshuam los yog txawm tias submerged los ntawm lub suab nrov nyob rau lub sijhawm no, thaum lub tshuab hluav taws xob ib leeg-photon nrhiav tau siv los ntsuas qhov teeb liab tsis muaj zog heev. Lub thev naus laus zis tshawb pom ib leeg-photon raws li gated InGaAs avalanche photodiodes muaj cov yam ntxwv ntawm qhov tsis tshua muaj tom qab-miv tes, lub sijhawm me me jitter thiab suav tus nqi siab.
Laser ntau yam tau ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw xws li kev tswj hwm kev lag luam, tub rog chaw taws teeb sensing thiab qhov chaw kho qhov muag vim nws cov yam ntxwv meej thiab nrawm, thiab nrog kev nce qib ntawm optoelectronic technology. Ntawm lawv, ntxiv rau cov txheej txheem pulse ntau yam thev naus laus zis, qee qhov kev daws teeb meem tshiab tau tsim tas li, xws li kev tshawb nrhiav ib leeg-photon thev naus laus zis raws li photon suav system, uas txhim kho kev tshawb pom kev ua haujlwm ntawm ib qho teeb liab photon thiab suppresses suab nrov los txhim kho. qhov system. qhov tseeb. Nyob rau hauv ib leeg-photon ntau yam, lub sij hawm jitter ntawm ib leeg-photon ntes thiab laser mem tes dav txiav txim siab qhov tseeb ntawm qhov sib txawv. Nyob rau hauv xyoo tas los no, high-power picosecond lasers tau tsim sai heev, yog li lub sij hawm jitter ntawm ib leeg-photon detectors tau dhau los ua ib qho teeb meem loj cuam tshuam rau kev daws teeb meem ntawm ib leeg-photon xws li tshuab.
