Abstract

An optical duplexer intended to receive light at a first optical wavelength and to transmit back light at a second optical wavelength, including, on a substrate, successive layers forming a photoreceptor of the first optical wavelength, a selective filter letting through the first optical wavelength, and a waveguide having a surface including a grating which is transparent for the first optical wavelength and diffracting for the second optical wavelength.
