9411480 McCaughan While Ti:LiNb03-based guided wave optics have produced the most sophisticated integrated optic structures to date, present devices lack the ability to produce or to amplify light. We propose to develop LiNbO3-based guided wave optical amplifiers and lasers, incorporating Er3+ as the amplifying medium and intersecting waveguides as a likely waveguide geometry. A new class of integrated optic devices will result from the successful integration of optical amplifiers and lasers with existing guided wave electro-optic elements. These will include integrable amplifiers to offset losses inherent in integrated optics, laser-modulator integration, tunable lasers for wavelength division multiplexing, and pulsed light sources. In order to carry out this research cost-sharing is provided to purchase a color-center laser. This instrument will enable characterization of several key fluorescence and absorption measurements over the wavelength range of 1450-1650nm. The laser will allow determination of parameters such as Er3 diffusion profiles and optimum waveguide geometries of diode pumping. In addition, it will permit extension of site-selective spectroscopy to the infrared. ***

9411480麦考恩虽然基于钛：LiNb03的导波光学器件已经产生了迄今为止最复杂的集成光学结构，但目前的设备缺乏产生或放大光的能力。我们建议发展LiNbO_3基导波光放大器和激光器，掺入Er3+作为放大介质，交叉波导作为一种可能的波导几何结构。光学放大器和激光器与现有的导波电光元件的成功集成将产生一类新的集成光学器件。这些将包括用于抵消集成光学中固有损耗的可积放大器、激光调制器集成、用于波分复用的可调谐激光器和脉冲光源。为了进行这项研究，提供了购买色心激光器的费用分摊。该仪器将能够在1450-1650 nm的波长范围内表征几个关键的荧光和吸收测量。该激光器将允许确定参数，如Er3扩散分布和二极管泵浦的最佳波导几何形状。此外，它还将允许将位置选择光谱学扩展到红外。***
