چکیده
激光波长调谐对于在压力检测、 强电场监测、 痕量气体探测以及可见光通讯领域中提高动态波长分配效率起着重要作用. 拉曼散射是一种具有频移特性的非线性光学效应, 这表明拉曼散射可能是一种实现激光波长调谐的可行方法. 在本文中, 我们发现在特定的测试结构下, 氮化铝的A1(TO)模式对应的散射光具有线偏振特性. 此外, 通过温度调制, 我们在氮化铝中实现了高精度的散射光波长调谐. 基于实验结果, 具有高热导率和高稳定性的氮化铝可能是一种实现激光波长调谐的良好载体.

Hopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
متن کاملSupersymmetry in Single Crystals
Supersymmetry. According to the theory of unbroken supersymmetry, for each fermion there exists a boson superpartner and for each boson there exists a fermion superpartner with the same fundamental characteristics (including mass and charge). But, broken supersymmetry states that all superpartners have masses much greater than their associated particles, leaving no hope to observe the unbroken ...
متن کاملTuning SOI filters with Liquid Crystals
The silicon-on-insulator (SOI) material system is today widely recognized as one of the most important platforms for the development of photonic components. This is mainly due to the fact that the mass fabrication techniques of the CMOS technology can be used for the fabrication of these SOI components. However, using silicon for photonic components has significant downsides. For example, it is...
متن کاملExciton acoustic-phonon coupling in single GaN/AlN quantum dots
Coupling of acoustic phonons to excitons in single wurtzite-type GaN/AlN quantum dots is investigated in detail by cathodoluminescence experiments and compared to theory. Numerical simulations of the coupling in the framework of the independent Boson model with realistic wave functions based on 8-band k · p theory show good agreement with observed emission line shapes. We analyze the influence ...
متن کاملMagnetotransport in Tb2Fe17 single crystals
We have performed measurements of the Hall effect, electrical resistivity, and magnetization on Tb2Fe17 single crystals in the 5 to 300 K temperature range, and in magnetic fields of up to 5 T. We find that the anomalous Hall effect of this ferromagnet depends strongly on the magnetization direction relative to the crystal axes. The AHE resistivity, measured with an applied magnetic field H per...
