A novel DVD/CD-R compatible integrated optical-pickup is proposed. In this device, the beam follows a zigzag optical path inside a planar glass substrate. A transmission planar combiner & splitter, an achromatic waveplate and a color separation grating were integrated on a glass substrate. With these elements, the system has the functions of combining and splitting the two wavelength beams, rotating their polarizations. Such a planar integrated optical-pickup is compact and lightweight with high energy usage ratio.
