We firstly demonstrate self-imaging phenomenon with symmetric interference in photonic quasicrystal waveguides.
- class="label">•
Based on self-imaging effect, a new kind of 3 dB power splitter for THz wave is proposed and simulated as an example.

This kind of THz power splitters exhibit the characteristics such as compact structure, low loss and large bandwidth.
