Abstract:
1. A method of fabricating a polymer waveguide device, the method comprising: providing a substrate having an electro-interconnection region and a waveguide region; forming a patterned dielectric layer, a patterned redistribution layer (RDL), and a patterned passivation layer over the substrate in the electro-interconnection region; bonding the patterned RDL to a vertical-cavity surface-emitting laser (VCSEL) through a bonding stack; forming a reflecting-mirror trench in the substrate in the waveguide region, wherein the waveguide region has a reflecting-mirror region and a wave-tunnel region; forming a reflecting layer over the patterned passivation layer, the patterned RDL, the reflecting-mirror region, and the wave-tunnel region; forming a patterned bottom cladding layer over the reflecting layer in the wave-tunnel region; and forming a patterned core layer and a patterned top cladding layer over the reflecting layer in the reflecting-mirror region and over the bottom cladding layer in the wave-tunnel region.
