This Small Business Innovation Research (SBIR) Phase I project will demonstrate photonic devices based on novel rare earth-aluminum oxide (REAl) glass. These devices exploit electronic transitions in rare earth doped and co-doped glass that potentially enable efficient laser action at wavelengths from 480 to 2250 nanometers (nm) when pumped by inexpensive diode lasers. Phase I will focus on the feasibility of devices having emissions at 1480 nm and possibly 1300 nm emission for telecommunications applications. The behavior of 480-490 nm emissions will be characterized with a view toward use in optical data storage applications. Phase I will also synthesize and characterize doped rare earth-aluminum oxide glasses, and establish protoype device performance. Measurements on the rare earth doped REAl glasses will include the spectral absorption coefficient at the pump wavelength, fluorescence cross section line shape, slope efficiency, fluorescence lifetime, single pass gain, and IR transmission.Potential commercial applications include small laser or optical amplifier devices to extend the fiber telecommunication bandwidth for use in high-density optical data storage devices.

这个小型企业创新研究(SBIR)第一阶段项目将展示基于新型稀土-氧化铝(REAL)玻璃的光子器件。这些器件利用稀土掺杂和共掺杂玻璃中的电子跃迁，在廉价的二极管激光泵浦下，有可能在480到2250纳米(Nm)的波长下实现有效的激光作用。第一阶段将侧重于将发射波长为1480纳米甚至可能为1300纳米的设备用于电信应用的可行性。将从光学数据存储应用的角度来表征480-490 nm发射的行为。第一阶段还将合成和表征掺杂稀土-氧化铝玻璃，并建立原型器件性能。对稀土掺杂的真实玻璃的测量将包括在泵浦波长的光谱吸收系数、荧光截面线形、斜率效率、荧光寿命、单程增益和红外透过率。潜在的商业应用包括用于高密度光数据存储设备的扩展光纤通信带宽的小型激光或光放大器件。
