Optical transceivers often require multi-wavelength lasers in data communications applications. However, scaling the laser array size increases self-heating and thermal crosstalk. This affects the energy efficiency of lasers which are sensitive to temperature, emphasizing the need for careful consideration of thermal performance during the design stage. Researchers have now developed a thermo-optic laser model and investigated the impact of design choices on laser self-heating and overall energy efficiency.

The trend of ever-increasing data center traffic has pushed for more efficient I/O links. Silicon photonics is a promising route to enable communication in the optical domain using … Read More → "Thermal Scaling Analysis of Large Hybrid Laser Arrays for Co-Packaged Optics, published in IEEE Journal of Selected Topics in Quantum Electronics"
