A bias controller and a method for controlling the bias of an electro-optic modulator are provided. In the method, for a received indication of modulator temperature, steps are provided for accessing a look-up table to determine a corresponding value of bias voltage, for a required bias point, to apply to the modulator. If no such value is stored, additional steps are provided to generate a pilot tone for input to the modulator and to recognise, from the signal content of a modulated optical signal output by the modulator, operation of the modulator at the required bias point, adjusting the value of bias voltage being applied to the modulator as required. When operation at the required biaspoint is recognised, the respective value of bias voltage for that modulator temperature is stored in the look-up table.The same method is provided to configure a bias controller in respect of a given modulator, if necessary ab initio. | ||||||

168 | Athermalized birefringent filter apparatus and method | EP08160140.3 | 2008-07-10 | EP2015133A1 | 2009-01-14 | Miller, Peter; Mirkin, Leo |
An athermalized birefringent filter (102) for shifts in center wavelength and in bandwidth incorporates fixed retarder elements such as quartz or film retarders, along with electrically-variable retarder elements such as liquid crystal variable retarder cells. A control mechanism determines the amount of thermal drift in the fixed retarder element and produces an equal change in the variable retarder element. The sign of the change depends on whether the variable retarder element adds its retardance with that of the fixed retarder element, or opposes it. This change compensates for the thermal drift of the fixed retarder element. Further, the variable retarder element is constructed to provide the necessary range of retardance adjustment for spectral tuning and thermal compensation over a target thermal range. The control mechanism ensures that, for any specified wavelength, the birefringent filter operates in the same order over the full target thermal range. Multispectral imaging systems (100) are provided based on these filters which provide athermalized response. |

The present invention relates to an apparatus for providing orthogonally polarized light beams for use in precision metrology applications such as in the measurement of length or length changes using interferometric techniques. An input beam (18) is introduced to a multifaceted anisotropic optically active acousto-optical crystal (47) for travel through an interactive region, it experiences two acoustic beams that diffract it via small angle Bragg diffraction to form two orthogonally polarized internal beam components that are separated by a small angle of divergence and subsequently become external beam components (30, 31) available outside of the acousto-optic crystal (47) for use in anticipated downstream applications. The acousto-optic crystal (47) preferably is a uniaxial crystal comprising TeO2. The degree of overlap or spatial separation between the energy flux profile of the orthogonally polarized, external beam components may be controlled by refracting properties of the acousto-optic crystal (47), its birefringence, the acoustical and optical properties of the acousto-optical crystal (47), the length of the physical path of travel experienced by the emergent beam through the acousto-optical crystal (47) and external birefringent elements. Thermal compensation may be provided via the control of the frequency of the first and second oscillators and/or the properties of the external birefringent elements. | ||||||
