Embodiment Construction
[0010] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0011] The arrayed waveguide interferometer in FIG. 1 includes an input optical waveguide 1, an output optical waveguide 2, and an arrayed optical waveguide 3 between them. The arrayed optical waveguide 3 is composed of no less than two optical waveguides 4. The array optical waveguide 3 is used to couple the optical wave field in the input optical waveguide 1 to the output optical waveguide 2 for interference superposition. In the figure, Iin and Iout represent the input and output light fields, respectively. In order to realize constructive interference, the light wave should be input from the input port of the input optical waveguide 1, and the optical path difference when passing through two adjacent optical waveguides 4 in the array optical waveguide 3 and reaching the output port of the output optical waveguide 2 is the wavelength of the output lig...
