Integrated Optics & Sensing

Find all the group members on UEFconnect

We create novel components, methods, and devices by exploring new possibilities and different aspects of conventional and unconventional systems… What if there was no limit?

By combining the computing power of CSC with the cleanroom facilities of UEF and our dedicated lab, we design, fabricate, and characterize customized photonic integrated circuit from fundamentals to prototypes.

More information about our research topics is given below.
