We report on the application of an integrated holographic device to the generation of two-dimensional (time-frequency) optical codes for use in optical code-division multiplexing based on wavelength encoding/time spreading. The dual code device is based on two holographic Bragg reflectors and allows one to encode data with either one of two complementary diagonal 16-chip temporal-spectral codes.
