Abstract
The invention relates to an optical interference filter device which defines a first periodic filter frequency response between a first filter output port and a filter input port and a second periodic filter frequency response having the same free spectral range as the first periodic frequency response between a second filter output port and the filter input port. The first and second periodic filter frequency responses are shifted versus each other by a predetermined optical frequency distance.
