摘要： An optical waveguide circuit includes a plurality of waveguides with different lengths. Grooves (12) are formed in the waveguide by removing the upper cladding and the core of the waveguide (4) or by removing the upper cladding, the core and the lower cladding of the waveguide (4), and filled with a material (10) which have a refractive index temperature coefficient whose sign is different from the temperature coefficient of the effective refractive index of the waveguide. The difference between the lengths of the removed parts of the adjacent waveguides is proportional to the difference between the lengths of the remaining parts of the adjacent waveguides.

摘要： An optical connector plug comprises a front housing (1), a rear housing (2), a ferrule (3), a coil spring (4), and a fiber fixture (5). The ferrule (3) and the coil spring (4), together with the fiber fixture (5) that joins a tensile material and the fiber clad, are held within a space defined when the front housing (1) and the rear housing (2) are united. The structure is such that the components (1-5) can be inserted one after another and moved lengthwise into the space when the optical connector plug is assembled. Therefore, the optical connector plug is suitable for automatic assembly.
