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，所以抑制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。可以通过减少与耦合到包层模式的芯的传播模式再次耦合到palnar光波导光栅中的芯的情况的发生的情况下，可以增加抑制，其通过沿着光的传播方向周期性地改变波导结构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折射率的包层。
