Modified Spontaneous Emission in Silicon Photonic Layer-by-Layer Structures

摘要

1. Woodpile crystals show 100% reflectivity in the bandgap region 2. Good agreement with calculated spectra 3. Reflectivity for a finite structure depends on polarization and surface orientation 4. Observation of a superstructure in the reflectivity 5. Internal light source: Quantum efficiency is important! Emission reduced in bandgap region Transmission 5 dB per unit cell.
