Device will enable complex photonic devices greater robustness

Devising a way to greater protect complex photonic devices from internal and external disturbances is a key issue in the photonics integration industry, but PhD candidate Andri Mahendra may have the solution.

Complex, complementary metal-oxide-semiconductor (CMOS)-compatible photonic integrated circuits (PICs) have been proposed for many applications, including sensing, communication and quantum computing and are being developed for industry.

Such developments will be crucial in upcoming years as data growth is expected to exponentially grow for industries associated with Web 2.0 data centres and Internet of Things environments, as well as the biomedical world that requires reliable photonic systems. 

In collaboration with physicists and engineers at CUDOS and the Australian Institute for Nanoscale Science and Technology (AINST), Andri has built an integrated multiple-input multiple-output (MIMO) circuits controller for controlling photonic systems.

Amongst the key advantages of the joint CUDOS postgraduate researcher’s approach is the enabling of reliable and adaptive reconfiguration of complex PICs. The integrated circuits controller can also be used as a modular and scalable photonic controller and has capabilities to simplify power supply instruments used by scientists in and engineers in experiments.

“Technology works simply by controlling conventional power supplies to a scalable manner with an intergrated controller to provide larger numbers of output channels,” said Andri, currently sponsored by the Indonesia Endowment Fund for Education program.

His work has been published in the Journal of Applied Optics. The invention, for which a US provisional patent has been filed, is called a reconfigurable power supply channel extender device or Xpow.
