We present the fabrication and optical characterization of waveguides in photonic crystals based on pillars. The waveguides were integrated in a classical photonic integrated circuit in InP technology. Photonic crystal waveguides of varying lengths were fabricated and measured. From 2D band diagram simulations, two different defect radii were selected while keeping the background photonic crystal the same. The waveguide with the larger defect radius (rdefect = 210 nm) shows lower coupling losses than the waveguide with rdefect = 170 nm. This is in agreement with simulations on the photonic crystal waveguides.
