摘要： PROBLEM TO BE SOLVED: To solve the problem that an entire adjustment step requires much labor because it is necessary to repeatedly irradiate a plurality of positions with ultraviolet rays while confirming a wavelength, a transmission spectrum shape, etc., and the problem that loss due to a channel formed on a waveguide is large to make a spectrum broad and reduce an extinction ratio in an adjacent channel, in a conventional manufacturing process of an optical wavelength multiplexer/demultiplexer.SOLUTION: Materials to fill a channel of an athermal AWG are suitable for filling a channel formed on a quartz waveguide, have high first-order coefficients of dn/dT, are free of transition of refractive indexes, have high transparency and low viscoelasticity, and are superior in reliability. These materials are mixed at a prescribed volume ratio or the like to be controlled to a desired refractive index. Because of the controllability of the refractive index, a center wavelength of the athermal AWG and a transmission spectrum shape can be freely controlled, and the adjustment step can be simplified. A refractive index of the filling materials is approximate to that of a core of the waveguide, whereby an AWG having a small loss due to the channel, a narrow spectrum, and filter characteristics of a high extinction ratio can be implemented.
摘要翻译：要解决的问题为了解决整个调整步骤需要大量劳动的问题，因为需要在确认波长，透射光谱形状等的同时反复照射多个位置的紫外线，并且问题在光波长多路复用器/解复用器的常规制造过程中，由于形成在波导上的通道导致的损耗大，使得光谱变宽并且降低相邻通道中的消光比。
解决方案：填充无热AWG通道的材料适用于填充石英波导上形成的通道，具有高的一阶系数dn / dT，没有折射率的过渡，具有高透明度和低粘弹性好，可靠性高。这些材料以规定的体积比等混合，以控制到所需的折射率。由于折射率的可控性，可以自由地控制无热AWG的中心波长和透射光谱形状，并且可以简化调整步骤。填充材料的折射率近似于波导的芯的折射率，由此可以实现由于沟道，窄光谱以及高消光比的滤光器特性而导致的损耗小的AWG。版权所有（C）2012，JPO＆INPIT
