Abstract:
A method of selectively demultiplexing a group of modulated intelligence bearing light beams comprising the steps of:(a) providing a K-vector selector for simultaneously performing K-vector division demultiplexing and detection of selected K-vector modulated intelligence bearing light signals, from said group of intelligence bearing light signals, within a particular portion of said K-vector selector; (b) selectively tuning the K-vector selector to a selected transmission K-vector light signal for causing the K-vector selector to transmit a selected light signal having such a selected transmission K-vector; (c) directing said group of beams bearing temporal signals having different K-vectors at said K-vector selector; and (d) detecting within said particular portion of the K-vector selector, modulation of said selected light signal having a selected transmission K-vector, transmitted by the K-vector selector, by application of a fluctuating temporal signal to said particular portion of said K-vector selector.
