| Abstract(in English) | We describe the successful realization of a low-loss single-mode waveguide in PLC glass composed of boron-phosphorus-doped glass, which is more difficult as regards waveguide writing than pure silica. The written waveguide has a rectangular core, a symmetric near field pattern, and a propagation loss of 0.35 dB/cm. The loss that originated from the mode-field mismatch between the mode field diameters of the written and PLC waveguides was less than 0.1 dB/point. In addition, we successfully connected PLC waveguides with a 500-μm-long waveguide written with a laser. The laser-written waveguide can flexibly connect PLC waveguides with a low coupling loss. |
