Abstract: According to an example, a plurality of pixels of a modulator upon which an input light beam impinges may be modulated to apply a first asymmetrical attenuation pattern on the input light beam and to direct a first attenuated light beam from the modulator and a first power level of the first attenuated light beam may be measured. The plurality of pixels may be modulated to apply a second asymmetrical attenuation pattern on the input light beam and to direct a second attenuated light beam from the modulator, and a second power level of the second attenuated light beam may be measured. A difference between the first power level and the second power level may be calculated and a modified peak frequency for an attenuated light beam from the calculated difference may be calculated.

Abstract: According to an example, an optical transmission device may include a spatial light modulator having a plurality of cells, in which different wavelengths of a light beam are to impinge upon different groups of pixels along a dispersion direction. The device may also include a driver mechanism to modulate, at a first frequency, a first group of the plurality of cells upon which light having a first wavelength impinges to impress a first frequency fluctuation onto a property of an output light including the first wavelength and to modulate, at a second frequency, a second group of the plurality of cells upon which light having a second wavelength impinges to impress a second frequency fluctuation onto a property of an output light including the second wavelength, in which the second frequency modulation differs from the first frequency modulation.

Abstract: According to an example, a polarization control system is to manipulate polarization manipulators to output light that achieves a trajectory on a Poincaré sphere that tracks a known trajectory of a polarizer on the Poincaré sphere, in which the trajectory of the output light enables definition of a reference polarization state of the output light. The polarization control system may also manipulate an output polarization manipulator to set the output light to a predefined polarization state based upon the reference polarization state.

Abstract: A test instrument tests an optical component of a fiber optic network. The test instrument determines signal parameters describing pulses to be emitted by lasers of the test instrument to test the optical component, and directly modulates the lasers to repeatedly emit the pulses at different wavelengths on a single fiber optic cable in a time division multiplexing manner. The test instrument triggers powering measurements to coincide with the emitted pulses, and determines performance parameters of the optical component based on the triggered power measurements.
