研究目的
Investigating the TE band structures in a two-dimensional photonic crystal waveguide composed of air holes in a background of GaAs.
研究成果
The study concludes that defective modes within the photonic band gap can be tuned to higher frequencies by increasing hydrostatic pressure, but rotating the triangular holes does not significantly affect the position of these modes within the gap.
研究不足
The study does not explore the effects of varying the temperature beyond a constant value of 4 K, nor does it investigate the impact of other external factors such as magnetic fields on the defective modes.
1：Experimental Design and Method Selection:
The study uses the plane-wave expansion (PWE) method and the supercell technique to determine the TE band structures.
2：Sample Selection and Data Sources:
A two-dimensional photonic crystal waveguide from a hexagonal photonic lattice with periodicity in the xy plane, composed of holes with triangular cross sections in a GaAs background.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The study involves numerical simulations to identify defective modes within the photonic band gap under varying conditions of hydrostatic pressure and rotation angles of triangular holes.
5：Data Analysis Methods:
The eigenvalue equation for TE polarization is solved to analyze the band structures.
