    • The invention relates to devices having periodic refractive index modulation structures and fabrication methods for the devices using a laser means. By focusing a pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. By selecting appropriate laser parameters and relative scan speed, the laser modified path defines an optical waveguide. Separation distance of the individual modified volumes define a periodic modification pattern along the waveguide path, so that the waveguide structures also exhibit grating responses, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. This method of direct laser fabrication enables one-step fabrication and integration of periodic or aperiodic refractive-index modulation devices together with optical waveguiding properties to enable low-cost, multifunctional I D, 2D or 3D optical circuit fabrication for simple and complex applications.
    • 本发明涉及具有周期性折射率调制结构的装置和使用激光装置的装置的制造方法。 通过将脉冲激光束聚焦到透明材料基板中,与未处理的材料相比,可以形成具有改进的折射率的激光修改体积的路径。 通过选择适当的激光参数和相对扫描速度,激光修改路径限定了光波导。 各个修改体积的分离距离定义沿着波导路径的周期性修改图案,使得波导结构也表现出光栅响应,例如作为光谱滤波器,布拉格反射器,光栅耦合器,光栅传感器或其它器件。 这种直接激光制造方法使得能够对周期性或非周期性折射率调制器件进行一步制造和集成以及光波导特性,以实现简单和复杂应用的低成本,多功能I D,2D或3D光电路制造。
