Abstract

Optical interconnection is a key technology for computer optical data links.[1][2] It is important to connect optical fibers to such devices as planar waveguides, LD arrays, and PD arrays. The connection must be high in density, easy to assemble, and low in cost. As regards connecting single-mode planar waveguides to a multifiber array, we have already proposed a basic passively aligned coupling method using two guide-pins.[3] However, there are some aspects of device fabrication which need to be improved. In this paper we propose a novel easily fabricated optical device for coupling single-mode planar waveguides to a multifiber array. This device uses fully passive alignment, which makes the assembly process easier, and also contributes to cost effectiveness.
