Abstract:
1. A communication method, comprising the steps of: illuminating a first detector with a first predetermined amount of a first optical signal carrying first information at a first wavelength and a first predetermined amount of a second optical signal carrying second information at a second wavelength to provide a first electrical output signal; and illuminating a second detector with a second predetermined amount of the first optical signal and a second predetermined amount of the second optical signal to provide a second electrical output signal; scaling the first electrical signal to provide a scaled version of the first electrical signal; scaling the second electrical signal to provide a scaled version of the second electrical signal; determining the first information by processing the first electrical signal with the scaled version of the second electrical signal to at least reduce the second information contained in the processed first electrical signal; and determining the second information by processing the second electrical signal with the scaled version of the first electrical signal to at least reduce the first information contained in the processed second electrical signal.
