Abstract: An optical receiver, transmitter, transceiver or transponder for bursty, framed or continuous data. The optical receiver includes a burst mode clock recovery module that recovers the clock rapidly and with a small number of preamble or overhead bits at the front end of the data. A local clock is used for timing when the recovered clock is not available. Transitions between the recovered clock and local clock are smoothed out to avoid undesirable artifacts.

Abstract: A heat removal system for use in optical and optoelectronic devices and subassemblies is provided. The heat removal system lowers the power consumption of one or more active cooling components within the device or subassembly, such as a TEC, which is used to remove heat from heat generating components within the device or subassembly. For any particular application, the heat removal system more efficiently removes the heat from the active cooling component, by using a heat transfer assembly, such as a planar heat pipe type assembly. The heat transfer assembly employs properties like, but not limited to, phase transition change and thermal conductivity to move heat without external power. In some embodiments, the heat transfer assembly can be used to allow the active cooling component, such as a TEC to be removed, leaving the heat transfer assembly to remove the heat from the device or subassembly.
