In this paper, we present the properties of flexible polymer planar optical waveguides made of EpoCore deposited on Xerox, Melinex, Hostaphan and Plexiglas flexible foil substrates. EpoClad polymer was used as cladding between a foil substrate and the waveguide layer. Waveguide properties were measured by dark mode spectroscopy for five wavelengths (473, 632.8, 964, 1311 and 1552 nm). Propagation optical loss measurements were done by the fibre probe technique at a wavelength of 632.8 nm (He-Ne laser). The best samples had optical losses of about 0.5 dB·cm-1, and the losses generally did not exceed 1 dB·cm-1. Unlike the other structures that have been presented, our construction is fully flexible, which makes it possible to be used in innovative photonic structures..
