Abstract
An optical device for combining optical signals of different wavelengths is described wherein an array of laser output beams are collimated, directed to propagate along a similar path, and coupled into an optical fiber through a single molded part. The single-part optical coupling module can be constructed in various ways to achieve the desired configuration. One example is a single plastic-injection molded part, containing mechanical alignment features, an array of collimating lenses, and a focusing lens housed within a fiber optic connector ferrule. The laser output beams are separately passed through separate radial sectors of the focusing lens.
