    Abstract: An optical waveguide which can suppress adjacent crosstalk even when wavelength intervals to be multiplexed/demultiplexed are narrow. A lower clad film and a core film are deposited and formed on a substrate (11) by flame hydrolysis deposition, and they are consolidated, whereupon the core film is processed into a waveguide pattern. The waveguide pattern is formed by successively connecting at least one optical input waveguide (12), a first slab waveguide (13), an arrayed waveguide (14) consisting of a plurality of channel waveguides (14a) arranged side by side and having lengths different from one another, a second slab waveguide (15), and a plurality of light output waveguides (16) arranged side by side. The waveguides arranged side by side are at intervals from one another. An upper clad film covering the waveguide pattern is deposited and formed by flame hydrolysis deposition, and it is thereafter consolidated. Herein, a sintering rate in a temperature rise from a temperature at which the density change of the glass particles of the upper clad film starts, to a temperature at which the density change ends, is set at 1.0null C./min or below at the step of consolidating the upper clad film, whereby the arrayal aspect of the channel waveguides (14a) is brought close to an ideal aspect.

    Abstract: A novel planar waveguide structure has been constructed by sintering substantially pure SiO.sub.2 layers in a He.sub.2 /BCl.sub.3 atmosphere. This results in the generation of a liquid phase of substantially lower viscosity than that of the deposited silica by itself. Since viscous sintering is enhanced by the presence of this liquid, consolidation occurs at lower temperature, e.g. 1000.degree.-1100.degree. C., than those used in the prior art, e.g. 1350.degree.-1500.degree. C. Much of the B.sub.2 O.sub.3 remains unreacted with the silica particles it helps to sinter, acting like a flux to bring about consolidation. This remaining B.sub.2 O.sub.3 is removed at the conclusion of the consolidation procedure by steam treatment at temperatures of 900.degree.-1100.degree. C. Some boron is incorporated into the silica layer, changing its CTE without substantially increasing its index. Thus, this method improves both structure and processing of planar waveguides by reducing the processing temperature and producing a glass which does not bow the substrate and essentially eliminates birefringence resulting in polarization dependent losses. This greatly benefits sophisticated circuits such as those intended for wavelength diversion multiplexing and allows narrow and precisely positional pass bands.

    Abstract translation: 通过在He2 / BCl3气氛中烧结基本上纯的SiO 2层来构造新颖的平面波导结构。 这导致产生比沉积二氧化硅自身明显低的粘度的液相。 由于这种液体的存在增强了粘性烧结，因此在较低温度下发生固结，例如， 1000°-1100℃，比现有技术中使用的那些。 1350°-1500℃。大部分B2O3仍然与二氧化硅颗粒未反应，有助于烧结，起到助焊剂的作用，从而形成固结。 在900°-1100℃的温度下，通过蒸汽处理，在固结程序结束时，除去剩余的B2O3。一些硼被掺入到二氧化硅层中，改变其CTE而基本上不增加其指数。 因此，该方法通过降低加工温度并产生不会对基板弯曲的玻璃并且基本上消除导致偏振相关损耗的双折射，从而改善了平面波导的结构和处理。 这对于诸如那些用于波长分流复用的复杂电路非常有益，并允许窄且精确的位置通带。
