We designed waveguide crossings with small angles by the wavefront matching method to reduce excess loss and crosstalk. The designed waveguide crossings were fabricated using silica-based planar lightwave circuit (PLC) technology. We experimentally obtained excess loss and crosstalk values of less than 0.3 and -30 dB, respectively, for a crossing angle of 5deg, and of less than 0.1 and -38 dB, respectively, for an angle of 20deg, in the 1530-1565-nm wavelength range. The designed waveguide crossings are promising as basic circuit elements for realizing more compact PLC devices
