Abstract(in English) | Recently, new planar lightwave circuit (PLC) components are under study, in response to the requirement of downsizing and cost reduction, to increase their refractive index difference A between cladding and core. Accordingly, we are developing 2.5%Δ silica-based PLCs. However, it is difficult to put the 2.5%Δ silica-based PLCs directly into practical applications because their coupling loss with a single mode fiber is as high as 2.9 dB/facet, raising a need for developing a spot size converter (SSC) to lower the loss. We have designed here, therefore, a new vertical SSC that has a broad core expanded in both horizontal and vertical directions, and fabricated the vertical SSC by combining plasma enhanced chemical vapor deposition (PECVD) and shadow mask. As a result, it has been confirmed that the use of the vertical SSC can significantly reduce the coupling loss between the 2.5%Δ waveguide and fiber to 0.06 dB/facet. |
