Abstract

Integrated optics technology offers the potential to reduce the size and cost of optical disk read/write heads. Fig. 1 shows how integrated optics technology can be used to generate short wavelength laser light in waveguides using second harmonic generation techniques. Most integrated optical devices depend on optical waveguides to transport laser light between the individual optical components comprising the integrated optical device. For practical use, a method to efficiently couple laser light into and out of the waveguide is necessary to interface the integrated optical device to an external application.
