Abstract
The present invention provides a wavelength interleaver comprising a first interleaving unit, a second interleaving unit and an adapting waveguide coupled between the first interleaving unit and the second interleaving unit; both the first interleaving unit and the second interleaving unit including an input waveguide, an output waveguide and a filter coupled between the input waveguide and the output waveguide. The present invention sets up the gap between the input waveguide and the filter, and the filter and the output waveguide for extending components usage specification of the signal transmission system. Therefore, there is no need to add unnecessary components in design, the size is smaller and the cost of the signal transmission system is reduced.
