ABSTRACT OF THE DISCLOSURE A ultra-compact optical readout device utilizing a binary optical element that provides a wide separation between diffraction efficiency peaks of different polarization modes so that sending and returning light can take distinct paths at the light source and detector, respectively, and also take the same paths at other regions of the device, enabling the simultaneous emission and detection of light for reading information from optical media. The specially designed contour of the binary optical diffracting element also provides the device with focussing capabilities without the need for a cylindrical lens at the detector or light source.
