摘要： An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core. The rejection bandwidth can be narrowed without increasing the grating length by forming the radiative mode-coupled optical waveguide grating in an optical waveguide wherein the mean relative refractive index difference of the core is greater than that of optical communication waveguides. The rejection can be increased by reducing the occurrence of cases wherein propagation modes of the core coupled to cladding modes once again couple to the core in palnar optical waveguide gratings formed by making periodic changes in the waveguide structure along the direction of propagation of light in an optical waveguide having a cladding with a lower refractive index than the core surrounding the core, by making the thickness of the cladding at least thirteen times the thickness of the core.
摘要翻译：具有辐射模耦合特性的光波导光栅，作为光学部件具有出色的稳定性和可靠性，其中由于使用掺杂有锗和硼的石英玻璃作为芯，因此阻带的中心波长具有低的温度依赖性。可以通过在光波导中形成辐射模耦合光波导光栅而不增加光栅长度来减小抑制带宽，其中芯的平均相对折射率差大于光通信波导的平均相对折射率差。可以通过减少与包层模式耦合的芯的传播模式再次耦合到光栅波导光栅中的芯的情况的发生的情况，可以增加抑制，所述光波导光栅通过沿着光的传播方向沿波导结构的周期性变化而形成光波导具有通过使包层的厚度至少为芯的厚度的十三倍而具有比围绕芯的芯的折射率低的包层的包层。

摘要： A method of producing an optical waveguide grating by exposure to light. An optical waveguide having a core composed of a material wherein the refractive index changes due to exposure to UV light is formed into an optical waveguide grating by applying a grating portion formation step wherein a grating portion is formed by irradiation with UV light at a predetermined spacing, and an overall exposure step after formation of the grating portion wherein the entire grating portion is irradiated with UV light. As a result, the effective refractive index of the grating portion is changed so as to allow the central wavelength to be adjusted without changing the rejection. Consequently, the grating properties can be precisely and easily controlled.

摘要： [Object] A fiber laser device capable of shortening the rise time of output laser light and suppressing laser light output except for an output period is provided. [Means to attain the object] A fiber laser device 100 includes: a seed laser light source 10, a pumping light source 20, an amplification optical fiber 30, a wavelength converter 71, a wavelength selecting filter 73, an output section 50, and a controller 60. The controller 60 controls the seed laser light source 10 and the pumping light source 20 to change from a preliminary pumping state to an output state. In the preliminary pumping state, the laser light is not output from the seed laser light source 10, the pumping light is output from the pumping light source 10, and the pumping light has such an intensity that the wavelength of the laser light emitted and output from the amplification optical fiber 30 is not converted by the wavelength converter 71. In the output state, the laser light is output from the seed laser light source 10, the pumping light is output from the pumping light source 20, and the laser light and the pumping light have such intensities that the wavelength of the laser light amplified and output by the amplification optical fiber 30 is converted by the wavelength converter 71.
