Abstract :
We present a design and investigation of a low-loss terahertz fiber consisting of crossed rectangular shaped dielectric strips and a supporting outer cladding. The core-guided mode can be effectively confined in the fiber core with a large portion of mode power distributed in air holes adjacent to the solid material, which results in a low absorption loss property of the fiber. Low dispersion transmission can be obtained due to the thinner dielectric strips. In addition, a high birefringence on a level of 10 -2 over a wide frequency range can be obtained by simply adopting crossed dielectric strips with different thicknesses.
