Silicon Photonic Crystals

Cefe Lopez

Silicon photonic crystals present a tremendous opportunity for integrating optics with electronics, but the challenges are daunting. This article highlights recent approaches toward fabricating silicon photonic crystals that could lead to applications in integrated optical devices, sensing and other areas.

Channel and transport have always posed major challenges for scientists and engineers looking to control the flow of water, traffic, information, or something else. From ancient times, hydraulic engineers have worked to channel water through ducts and pipes and store it in dams for future use. Electrical engineers perfected the transport of electric current through metallic wires and semiconductors. Likewise, modern engineers channel light through optical fiber in optical communication technology. Now, however, a looming question is how to store light for future use.
