Membrane photonic crystals (PCs) provide a pathway for realizing photonic devices with high-quality optical confinement, but traditionally face high insertion losses due to an impedance mismatch with other waveguide modes. This letter demonstrates an innovative impedance matching design for PC waveguides, utilizing inverse taper structures to significantly reduce insertion losses to about 12 dB, making them more suitable for applications in optical processing, particularly in III-V semiconductor devices. The findings suggest that careful design can improve transmission and minimize reflection without additional processing steps.
