Abstract
The present invention is an optical spectrum analyzer (OSA) comprising a tree-structure of N-stage wavelength filters or “wavelength slicer” which “slice” the incident optical signal into desired groupings of individual sliced spectral components, each along a different output optical fiber. Cascaded fiber Bragg gratings and delay lines coupled to each output optical fiber then uniquely map the “sliced” spectral components into the time domain such that each spectral component is allocated a unique time slot.
