Abstract: The specification describes an optical wavelength monitor/analyzer that uses a cost effective wavelength reference source. The wavelength reference source is a nominally fixed wavelength laser with inherent tunability over a very limited wavelength range, i.e. a few nanometers. Tuning is effected by changing the temperature of the laser. The limited range is useful for making multiple wavelength measurements in the context of analyzing wavelength drift in tunable optical filters.

Abstract: A photodiode (PD) array accurately measures incident optical power on each of the PDs in the array by eliminating the effect of crosstalk between the individual PDs. Crosstalk within the PD array is removed by measuring the current generated by each PD in the array and generating a corrected optical power value for each PD that is based on the measured current for each PD and on coupling coefficients associated with other PDs in the array. The coupling coefficients are determined during a previous calibration procedure.

Abstract: Described are tunable multiport optical filters that filter systems with many optical channels in a convenient and cost-effective manner. The tunable multiport optical filters of the invention are simple in design and have few optical components. The basic elements are a dispersion element and a rotating reflector. With properly arranged arrays of input and output optical fibers, individual wavelength components from a selected input beam are spatially separated and steered by the rotating reflector to selected output locations. The optical properties from the selected components may be measured by one or more photodetectors. The filters are also useful for selecting and routing optical signals.
