• We present the simulation, fabrication and characterization of novel low-loss photonic crystal (PhC) defect waveguides for transverse magnetic (TM) polarized light in the InP/InGaAsP material system. Minimal propagation losses for the proposed W4 PhC waveguides as low as ${\sim}300$ dB/cm at $\lambda = 1550$ nm for lattice constant $a = 350$ nm, and ${\sim}500$ dB/cm at $\lambda = 1532$ nm for lattice constant $a = 590$ nm are obtained from the cut-back analysis. In addition, an associated application of proposed wide PhC waveguides as intermediate short tapers between deeply etched access waveguides and narrower quasi-single-mode PhC waveguides is investigated. Predicted improved coupling efficiency has been validated experimentally.
