All-Optical Method For Nanolaser Arrays

Researchers have created an all-optical method for driving multiple highly dense nanolaser arrays, which could lead to chip-based optical communication links that process and move data faster than current electronic devices. The use of optical fiber eliminated the need for large and complex electrodes, which are commonly used to power laser arrays.

According to the researchers, this all-optical method allowed them to reduce the overall dimensions of the laser array while also eliminating heat generation and processing time delays associated with electrode-based drivers.

The development of optical interconnects outfitted with high-density nanolasers would improve data processing in data centers, including those transporting data across the internet. It could enable the streaming of ultrahigh-definition movies, larger-scale interactive online encounters and games, the acceleration of the Internet of Things expansion, and the fast connectivity required for big data analytics. Integrated optical devices on a chip are a promising alternative to electronic integrated devices, which are struggling to meet today’s data processing demands.

As an alternative to the electrodes commonly used to pump nanolasers, the researchers used a novel optical driver that generates programmable light patterns via interference. This pump light passes through an optical microfiber that has nanolasers printed.
