India, July 23 -- In a new study published in IEEE Journal of Selected Topics in Quantum Electronics, Dr. David Coenen and his team developed an experimentally validated thermo-optic laser model. The model is demonstrated for a case study where a transceiver with 64 laser output channels is required.
To identify the configuration which is energy efficient, reliable and occupies a small area, the following input parameters were studied: how many lasers can fit in one die, laser die size, output power per laser gain, ambient temperature, thermal management strategy and finally integrated vs. external laser.
We found several interesting conclusions: there exists a clear trade-off between laser array area and overall thermal resistance. A s...
