CONNECT researchers publish OFC breakthrough in Nature Comms

CONNECT researchers Aleksandra Kaszubowska Anandarajah in Trinity College Dublin, and Prince Anandarajah and Prajwal D. Lakshmijayasimha in Dublin City University have published a paper in Nature Communications which reports the successful combination of two Optical Frequency Combs.

The breakthrough is significant as it will enable chip-scale microcombs with record-low energy consumption. These can be used in several areas including optical metrology, high-frequency electrical signal generation, optical atomic clocks, and high-precision spectroscopy.

This is the first time a gain-switched comb was used to pump a microcomb, reducing the optical pump power threshold by one order of magnitude, to a record-low level of a few milliwatts.

Optical Frequency Combs are used in a variety of applications such as transmitters in optical telecommunications, sensors for explosives or dangerous gases, and LiDAR for robotics and autonomous cars.
