This paper demonstrates the elasto-optic behavior of the one dimensional (1D) 4-C-max clustered disordered photonic crystals. To study the effects of pressure, 2, 5, 10 and 15% of defective layers were introduced over the binary random structures. The 4-C-max clustered disordered structure is composed of polymer materials (PMMA and PS). The additional Silicon dioxide (SiO2) layers are inserted into the random system, which acts as the defect layers. The optical properties of the clustered structure under pressure are numerically calculated using the transfer matrix method. The designed wavelength, lambda is maintained at 1550 nm for optical communication purposes. When the pressure increases from 0 to 6 GPa, depending on the percentages of defective layers, there exist changes in the width of the transmission peaks. These transmission peaks appeared within the chosen spectrum (1547-1553 nm). Numerical simulations indicate the occurrences of transmission peaks with a quality factor of 775000 at 1550 nm. Moreover, the aggregated structures show the monotonic decrease of the total transmission as the function of defects and pressure. The proposed system provides a linearity scale up to 99% (i. e.R-2 = 0.99). The photoelastic properties of the 1D clustered structures are very interesting for the modelization of the filters and sensors.
