Abstract

Anordning for å generere ut fra en enkelt lyspuls av kort varighet et tog ned synkrone lyspulser hver Innbefattende 1 det minste en foton 1 gjennomsnittet.nordningen Innbefatter flere optiske baner (lj, I....l) hver dannet 1 det minste av en optisk fiber av en-modus typen med null spredning 1 form av en lukket sløyfe 1 seg selv ved ende mot ende forbindelse ved sine ender ved hjelp av 1 det minste en kontakt. Antall sløyfer er n dersom antall N fotoner 1 lnltlalpulen er større enn 10n. Disse eløyfene er forbundet sammen to og to fulgt etterhverandre ved hjelp av første optiske retnlngskoplInger (2,>••-2(n-)' med relativt liten optisk kopllngskoeffeslent lik omkring. ()1/(n1); andre optiske retnlngskoplInger (33). som også har relativt lav optisk kopllngskoeffeslent. forbinder den første sløyfen (li) og den siste (l) sløyfen med eksternoptlske baner (hhv. 4 eller 7: 6 eller 8) hhv. for Inngangen til kun en liten del av lnltlallyspulsen og for utgangen, til toget med pulser med lik avstand dannet ved minst en enkelt foton 1 gjennomsnittet. Botasjonsperloden til fotonene 1 sløyfen er lik et helt tall. primtall 1 forhold til hverandre, med elementære perioder T. Rotasjonsperloden til fotonene 1løyfene er tilstrekkelig liten, slik at fotonene son forblir 1 sløyfene ved slutten av sampl lngsprosedyren, Ikke danner en bakgrunns tasy som er brysom ved den følgende sampllngsprosedyren.
