- We propose the novel method for fabricating photonic crystal microparticles with internal
woodpile structures by combining the hot-embossing process and prism holographic
lithography (HL). Hot-embossing process using PDMS elastomeric mold define the
micron-sized disks. These microarrays have internal woodpile structure with various
reflectance peak position by controlling exposure time during prism HL. Using reactive ion
etching to remove residual layer and dissolution of a pre-coated sacrificial layer, we can
finally obtain free-floating photonic crystal microparticles that were released from the
substrates. Owing to the porous structure of these free-floating HL microparticles, they
exhibit highly enhanced fluorescence intensity and sensitivity of surface-enhanced Raman
scattering (SERS) which suggest various applications [3-5].
