Abstract
Filters shaped differently from those commonly used in WDM Mux/DeMux optical devices are described. Different from the prior art devices that commonly use filters shaped in cuboid, the filters in the embodiment of the present invention are shaped in parallelepiped. In other words, a cross section of such filter is not in parallelogram. According to one embodiment of the present invention, a filter is so cut that a cross section thereof presents a cutting angle not being 90 degrees. As a result, the filter is fully used in WDM Mux/DeMux optical devices. Such filters are advantageously used in compact optical modules.
