Abstract

A fiber waveguide optical subassembly uses the multi-mode fiber to increase the alignment tolerance between the active optical element and the waveguide. The filter is thinner to lower the dispersion due to the optical coupling gap. The subassembly further combines the optical bench to achieve passive positioning. Therefore it reduces the cost and enhances the transmission rate.
