Integrated-optics planar components

Optical fiber architectures of the future are envisioned to employ extensive splitting of optical signals, as well as multiple wavelength division multiplexing and demultiplexing. These architectures and networks have motivated the development and commercialization of today's planar passive components. Beyond and including these applications, the prospects for new and exciting uses of planar devices are excellent. Planar passive components already are providing such functions in what is known as fiber-in-the-loop (FITL) systems. These applications are discussed.<
