Abstract
In order to develop key technologies for a multichip module with optical interconnection, a test module using polyimide optical waveguides (POWs) with micro-mirrors and a photodiode array was successfully fabricated. Through the fabrication of this test module, we developed such basic technologies as POW formation, vertical optical coupling with micro-mirrors buried in POWs, chip bonding with copper bumps, and so on. The signal propagation in POWs was characterized by the detection of vertical output signals at micro-mirrors. From these characteristics, the transmission loss caused by passing a mirror was evaluated to be 0.16 dB.
