博士 === 國立交通大學 === 電子工程系所 === 97 === The photonic crystal slab waveguides based on antiresonant reflecting optical waveguide (ARROW) structures are proposed for improving the butt-coupling efficiency with a single-mode fiber. Lightwaves propagating in this waveguide are confined by the photonic band gaps in lateral and antiresonance reflection in vertical. Numerical methods for analyzing and designing this devices are introduced. Modal characteristics of the ARROW structures are revealed. The photonic band structures and transmission behaviors of the two-dimensional photonic crystal waveguides are discussed. By combining the advantages of these two devices, the ARROW-based photonic crystal waveguides are analyzed and designed. In this platform, the important devices such as the 60, 120 sharp bends, and Y-branch waveguides are designed for substantially reducing the areas of the photonic integrated circuits. The three-dimensional copper photonic crystals with two feature sizes were fabricated layer-by-layer. The optical properties of the photonic band gaps for both structures have been investigated by experimental observation and simulation verification. With these devices, the suppression of the thermal emission in the ranges of band gaps and the narrow-band emission near the band-edge wavelengths have been experimentally observed.
