Ultrafast Optically Activated Switching in Semiconducting Materials
Within the past decade a virtual explosion in integrated optics has assured optical microcircuits a place of importance in future communication applications. For reasons which are mostly connected with the ready availability of highly transparent optical materials in the 1 μm wavelength region, relatively little attention has been directed at the longer infrared wavelengths in this connection. Yet given the posibilities of infrared optical radar and satellite communication, based, e.g., on CO2 laser sources, it would seem that wide bandwidth infrared optical microcircuits will have a not insignificant future role to play in i. r. signal processing. As evidenced by two articles in this volume, we are beginning to see results of recent efforts, directed at the development of infrared fibers.
