A hollow core photonic crystal resonant cavity for a terahertz gyrotron oscillator is proposed. The dispersion, mode structure, and confinement loss in this structure are theoretically derived. For advanced applications in the terahertz regime, the utilization of high-order modes, as well as mode competition issues, is discussed. The mode selectivity of the hollow core photonic crystal structure is demonstrated by utilizing a narrow bandgap to confine the design mode; meanwhile the competing modes are designed to have high confinement loss and weak beam-wave interaction efficiency. According to the mode selectivity, a mode selective hollow core photonic crystal terahertz gyrotron oscillator is designed.
