Abstract: In general, a temperature control device for use in laser assemblies and optical subassemblies is disclosed that includes at least two electrically conductive terminals to enable flexible electrical coupling to associated components, e.g., monitor photodiodes and laser diodes, and accommodate a range of laser assembly configurations without the necessity of supplying a negative voltage rail. In more detail, a temperature control device consistent with the present disclosure includes a bottom plate, a top plate, and a plurality of semiconductor elements disposed therebetween. The top plate includes a component mounting surface that provides at least a first and second electrically conductive terminal/pad. The first and second electrically conductive terminals/pads can be electrically isolated, e.g., via a gap, and configured to provide first and second voltage potentials respectively.
