Nowadays communications require a continuous increase,of data rates and, as far as the single customer is concerned, there is a severe bottleneck in the last kilometer of the transmission line. The only viable solution to this problem is the Fiber to the Home (FITH) system, which requires an amplification of the incoming signal in the optical fiber. However, the device of election, the Erbium Doped Fiber Amplifier (EDFA), is still very expensive, so that new optical waveguide amplifiers based on Lithium Fluoride (LiF) thin layers containing color centers have been recently proposed. Such electronic defects are characterized by broad absorption bands in the visible and near ultra-violet (UV) spectral range and by efficient, broad-band emissions extending from the visible to the near-infrared (NIR). One of the important properties of these light emitters arises from the short lifetime, several nanoseconds, which is a fundamental feature for high gain laser media. Several basic and technical aspects of novel solid-state amplifier configurations based on active waveguides in LiF will be presented and discussed.
