Embodiment of optical interconnection circuits for the mobile phone application

This paper intends to show that the optical interconnection can be a substitute of the electrical serial interface in mobile application. We designed the optical interconnection interface circuits on the evaluation boards which typically correspond to the mobile phone and transferred the data through the optical waveguide module. There are 4 pairs of VCSEL (Vertical Cavity Surface Emitting Laser) and PD (Photo Diode) arrays in the waveguide module and they are used to send the strobe and the data signal in dual-simplex (i.e. Two Directions with Unidirectional Lanes) configuration. We have demonstrated a successful data transmission of moving picture and real-time camera module images to the main-LCD (Liquid Crystal Display) repeatedly and the still pictures to the sub-LCD at the maximum speed of 400Mbps.
