APPARATUS AND METHOD FOR MEASURING OPTICAL POWER AS A FUNCTION OF WAVELENGTH

摘要

A system and method are disclosed for measuring optical power as a function of wavelength. Exemplary embodiments of the present invention comprise a waveguide structure having at least one waveguide. The at least one waveguide is comprised of an electro-optic material. The at least one waveguide includes an input end for receiving a beam of optical energy and an output end. A plurality of electrodes are disposed in close proximity along a longitudinal axis of the at least one waveguide. The voltages on a sub-plurality of the plurality of electrodes are independently controlled to alter the index of refraction of the at least one waveguide at positions adjacent to each sub-plurality of electrodes to pass a selected portion of the beam of optical energy. The output end passes the selected portion of the beam of optical energy to, for example, an apparatus that measures incident optical energy.
