—For any electronic device, junction temperature is the final temperature after that device became dead. In this paper the temperature of PN based optical transmitter is regulated using heat sink and airflow. Target device is operated at different operating frequencies for LVCMOS IO standard (LVCMOS12, LVCMOS15, LVCMOS18 and LVCMOS25) with two airflow values (250 MFL and 500MFL) and Heat sink values (Low profile, Medium profile and high profile). There is overall 20% reduction at 1000GHz the reduction for LVCMOS12 and for LVCMOS25 71% reduction is recorded for junction temperature. At all frequencies the heat sink profile and airflow significantly reduces the junction temperatures for target devices using LVCMOS25 IO standard. This design makes the target device, energy efficient. Finally this system will be integrated with other optical components to make optical communication system green. Xilinx ISE188.8.131.52 design tool is used to perform the experiment.
