Based on the phase variation compensation theory, we realize an angle-insensitive mid-infrared photonic bandgap (PBG) in a one-dimensional photonic crystal (1DPC) containing single-material semiconductor hyperbolic metamaterial layers. Under proper design, the bandwidth of the angle-insensitive (omnidirectional) mid-infrared PBG can reach 2.438 . The designed 1DPC is a simple single-material system composed of undoped and doped InAs, which can be fabricated by the molecular beam epitaxy technology under the current experimental conditions. Besides, the angle-insensitive property of the designed mid-infrared PBG is quite robust against the layer thickness. This broadband angle-insensitive mid-infrared PBG would possess potential applications for mid-infrared quantum cascade lasers, mid-infrared gas detectors, mid-infrared photothermal imaging, and protein analysis.
