Since the realization of the first laser 40 years ago, the merging of the fields of quantum electronics and quantum optics has stimulated the development of many new materials and devices. These, in turn, support a flourishing optoelectronics market for optical communications, optical data processing, medical diagnostics, materials processing, display technology, and many other applications. Therefore, in the year 2000, it is timely to publish The Handbook of Advanced Electronic and Photonic Materials and Devices. The editor, Hari Singh Nalwa, is well known for his original work on nonlinear optics of organic molecules and polymers. Together with Seizo Miyata, he edited a comprehensive volume under this title that provides a broad overview of this particular subject. The same authors also edited a volume on organic electroluminescent materials and devices.
