Abstract

We reported the controlled growth and optical properties of porous nanocolumnar structures by the oblique angle deposition (OAD) method using an electron-beam evaporation system. Distributed Bragg reflectors, graded refractive index films, and antireflective coatings were studied to apply to various devices including vertical cavity surface emitting lasers, light-emitting diodes, solar cells, and sensors. The characteristics of the fabricated devices were measured. These results suggest that the tailoring of optical properties by a simple OAD technique is very promising for optical and optoelectronic device applications.
