Photonic Computing

The Science Partner Journal (SPJ) Intelligent Computing is now seeking submissions for a special issue, Photonic Computing.


Over the last 50 years, microelectronics has supported the increasing demand in computing power thanks to an exponential performance scaling in digital electronics embodied in Moore’s and Dennard’s laws, by which the density of transistors and power efficiency in microprocessors has approximately doubled every 18 months. However, these empirical laws are reaching their fundamental limits and, consequently, there is currently a wide range of emerging real-time computing applications, which may not be exclusively covered by the dominant digital electronics paradigm. In fact, this technology is known to be inherently inefficient to perform linear analog operations and computational problems that are distributed, parallel, and adaptive. Analog computing approaches implemented in alternative technologies can be mathematically more efficient than digital computation to solve these classes of computational problems and may provide hardware advantages over electronics. 

Photonic computing is attracting the attention of multiple research groups, institutions, and industries, as it is an ideal candidate to explore analog computation paradigms in a hardware platform with complementary features to electronics, providing lower latency, higher bandwidth, massive parallelism, lower power consumption and reconfigurability.

This special issue focuses on the subject of Photonic Computing and aims to bring together and disseminate the latest advances reported by key players worldwide on the different aspects that are relevant. It also aims at providing a one-stop comprehensive resource to interested researchers wishing to get an up-to-date introduction to the field.
