Abstract
The potential of the optical circuit packaging technology is discussed. Special attention has been paid to introduction of "Optical wiring" into the Printed Wiring Board level ("last 1 meter area") to overcome conventional electrical copper-based bandwidth limitations. Optical Surface Mount Technology (O-SMT) can be one of possible solutions in this field is reviewed. High efficiency and alignment-free coupling between optical wirings and optical devices is a key. O-SMT requires a method to change the beam direction from the horizontal to the vertical and vice verse in order to couple between optical wirings in an OE-board and OE-devices mounted on the board. A novel method using an "Optical Pin" has been proposed and investigated. Furthermore, an optical coupling method using a Self-Written Waveguide called "Optical Solder" has been investigated. Several applications of self-written waveguides using a green-laser and a photo-mask are demonstrated.
