Motivated by resent experimental realization of a 1D strain-tunable photonic crystals and also increasing successes in strain-engineering in grapehene, we demonstrate the capability of a controllable photonic bandgap of a 1D graphene-dielectric photonic crystal by uniaxial strained graphene exhibiting either shrinkage or broadening along different chain crystalline orientations. Moreover, more analyzing over an electric field deviation angle to the stretching direction shows that the photonic spectrums are more sensitive to stronger deformations. Finally, we address how some resulting locked-up situations provide the measurement of the strain dependence of the chemical potential which is of considerable concern to be detectable as well as different strain states.
