A $2\times 2$ photonic crystal fiber (PCF) planar lightwave circuit (PLC) splitter, which splits optical power between two PCF channels, has been made by PCF-to-PLC connections. PCF array blocks were lithographically fabricated to have fiber V grooves and used to firmly hold PCFs and align them to the PLC splitter. The proposed splitter showed a rather flat splitting ratio over a wide wavelength range from $1250\mathrm{nm}\text{to}1750\mathrm{nm}$ . With the implemented splitter, we obtained a low excess loss of $1.6\mathrm{dB}$ , a low polarization-dependent loss of $0.1\mathrm{dB}$ , and a high return loss of $52\mathrm{dB}$ . The ultrabroadband operation of the proposed splitter is expected to find applications in optical performance monitoring, Ethernet passive optical networks, and biomedical optics including optical coherence tomography.
