Abstract
A programmable encoder is provided that includes at least one optical input for receiving a modulated broadband optical signal and at least one optical output. A dispersion element receives the optical signal from the optical input and spatially separates the optical signal into a plurality of wavelength components. A collimating element is provided for collimating the plurality of wavelength components. An actuatable optical arrangement receives the collimated plurality of wavelength components from the collimating element. The actuatable optical arrangement includes a digital micromirror device (DMD) from which a programmably selected subset of wavelength components are reflected at least twice before being directed to a selected one of optical outputs to thereby encode the CDMA signal.
