A thin-film Fabry–Perot filter (FPF) was designed and fabricated to achieve the superprism effect. A polychromatic light, tuned at various incident angles onto the device, was used to attain more demultiplexing channels. This indicates that the FPF, which can be fabricated simply and inexpensively, can be used as a tunable demultiplexing device. Further, the transfer matrix method (TMM) and the Gaussian angular spectrum method were introduced to calculate a more-accurate spatial shift at different wavelengths and to analyze the beam-splitting phenomena in the FPF.
