A digital volume holographic database in iron-doped lithium niobate to be read out by a multi-wavelength signal in the near infrared is here successfully performed, thanks to so-called two-color technique. Three 4-bit digital words have been recorded via angle multiplexing at 488 nm and retrieved at 1550 nm by a 200 GHz-WDM (Wavelength Division Multiplexing) beam.

Abstract
A digital volume holographic database in iron-doped lithium niobate to be read out by a multi-wavelength signal in the near infrared is here successfully performed, thanks to so-called two-color technique. Three 4-bit digital words have been recorded via angle multiplexing at 488 nm and retrieved at 1550 nm by a 200 GHz-WDM (Wavelength Division Multiplexing) beam.File in questo prodotto:
