(a) Peak positions of the reflection spectra measured from the SCPhCs were 910 and 923 nm, respectively, before and after photocrosslinking was performed using a UV adhesive solution. (b) Unpolarized angular-resolved reflection measurements of c-SCPhC thin films. (c) Measured transmittance of the c-SCPhC thin films.
