Abstract

Photorefractive phenomena such as optical phase conjugation and energy coupling via wave mixing have been studied extensively in photorefractive waveguides, fibers, and bulk crystals for a wide range of applications. In many of these applications, the photorefractive device can be viewed as an adaptive spatial mode converter which converts one spatial wave-form to another in real-time with a very high conversion efficiency. In this paper, I briefly review the basic principle and the experimental investigations of adaptive spatial mode conversion using photorefractive dynamic holograms and discuss their potential applications for the coupling of laser light into and out of waveguides and/or fibers. Recent progress in the research and development of two novel techniques for efficient and fault-tolerant laser-to-fiber coupling and multimode-to-singlemode fiber-optic coupling is treated in more detail and technical issues that need to be addressed to advance these techniques towards practical applications are outlined.
