Abstract:
1. A fiber optic wavelength dispersive device comprising: a front-end unit comprising a first port for launching an input optical signal; a wavelength dispersive reflector for receiving the input optical signal, for dispersing the input optical signal into a plurality of sub-beams of light with different central wavelengths, and for directing said sub-beams back at first angles along first optical paths in a dispersion plane; a spherical reflector for redirecting the input optical signal launched from the first port to the wavelength dispersive reflector, and for redirecting the sub-beams from the wavelength dispersive reflector back along second spatially separated optical paths; and, an array of beam receiving elements for receiving each of the sub-beams at a different location along the array according to the central wavelength thereof; wherein the wavelength dispersive reflector comprises:
