A semiconductor laser device includes a substrate having a first surface and a second surface opposite to the first surface, an active region formed on the second surface of the substrate, a cladding layer formed on the active region, and an insulation region formed in the cladding layer to form on the second surface of the substrate a first laser region having a first size and a second laser region having a second size different from the first size. The first laser region is used for generating a first optical spectrum having a first laser mode channel space. The second laser region is used for generating a second optical spectrum having a second laser mode channel space. A combination of the first optical spectrum and the second optical spectrum forms a single mode laser. Without any gratings, the semiconductor laser device is easy to be fabricated and has a low fabrication cost.

An optoelectric converting substrate includes a substrate, at least one honeycomb-shaped micro-structured optical waveguide embedded in the substrate and having two ends exposed through the substrate, a plurality of optoelectronic elements disposed on the substrate and coupled with the two ends of the honeycomb-shaped micro-structured optical waveguide, and a plurality of IC driving elements disposed on the substrate and electrically connected with the optoelectronic elements by conductive wires to drive the optoelectronic elements such that optical signals are transmitted through the honeycomb-shaped micro-structured optical waveguide. The optoelectric converting substrate can be easily fabricated at a low cost and effectively increases the displacement tolerance of the optoelectronic elements in substrate packaging.
