Abstract:
A method of fabricating an optical component comprising the steps of: providing a detector array having more detectors than a number of known channels; providing an input port and dispersive element within a waveguide structure, the dispersive element disposed for receiving light provided at the input port and for dispersing the light onto a plane disposed adjacent the detector array, the light dispersed other than as channelised data a within the known channels and the detector array having detectors along a length substantially exceeding the length of the light within the known channels dispersed along the plane; and, determining an operator for transforming spectral data sensed by the detector array into values indicative of intensity of light within each of the predetermined wavelength ranges corresponding to the known channels, the operator is dependent upon array location adjacent the plane to correct for tolerances in array placement, and upon optical variations in the waveguide and included structures for compensating therefore, with the operator accommodates variable data provided in response to external sensor data.
