Abstract: | A one-dimensional waveguide photonic structure—specifically, a photonic crystal with a controllable frequency characteristic—is
designed. The central frequency of the spectral window of the photonic crystal can be tuned by choosing the parameters of
disturbance of periodicity in the photonic crystal, whereas the transmission coefficient at a particular frequency can be
controlled by varying the voltage at a p-i-n diode. It is shown that the possibility exists of using the waveguide photonic crystal to design a microwave device operating
in the 3-cm-wavelength region, with a transmission band of 70 MHz at a level 3 dB and the transmission coefficient controllable
in the range from −1.5 to −25 dB under variations in the forward voltage bias at the p-i-n diode from zero to 700 mV. |
