摘要:
Provided are a method and structure for optical connection between an optical transmitter and an optical receiver. The method includes the steps of: forming on a substrate a light source device, an optical detection device, an optical transmission unit electrically connected with the light source device, and an optical detection unit electrically connected with the optical detection device; preparing a flexible optical transmission-connection medium to optically connect the light source device with the optical detection device; cutting the prepared optical transmission-connection medium and surface-finishing it; and connecting one end of the surface-finished optical transmission-connection medium with the light source device and the other end with the optical detection device. Fabrication of an optical package having a 3-dimensional structure is facilitated and fabrication time is reduced, thus improving productivity. In addition, since the optical transmission-connection medium is directly connected with the light source device and the optical detection device, a polishing operation or additional connection block is not required, thus facilitating mass production.
