Methods for linearization of photodetector response include establishing one or more static calibration coefficients based on comparison of test photodetector response to a linear reference photodetector. In some examples, dynamic calibration coefficients are determined based on average photodetector signals. In some applications such as FTIR, linearized ratios are obtained with a single calibration coefficient.

A laser mount assembly includes a lens holder including a collimating lens. A laser subassembly is positioned adjacent the lens holder and includes a vertical-cavity surface-emitting laser, a thermal electric cooler, and a thermistor. A printed circuit board is positioned adjacent the laser subassembly and includes a plurality of heating components. The heating components heat the area between the lens holder and the laser subassembly.

An apparatus and method for reducing EMI generated by a power conversion device, as well as a power conversion device employing such apparatus or method (and/or devices employing such a power conversion device) are disclosed. In at least some embodiments, the apparatus includes a hybrid filter for use in reducing EMI. The hybrid filter includes a passive filtering component, and an active filtering component coupled at least indirectly to the passive filtering component. The active filtering component includes a voltage controlled voltage source, and the hybrid filter operates to reduce a level of a common mode current, whereby the EMI generated due to the common mode current is reduced.
