Project

Dual Fano resonances for high speed optical communications

Publisher

Supervisor

Location

Greater Copenhagen area

As electronics in modern computers are forced to operate at ever-higher frequencies, power dissipation and consequent hardware heating due to resistive loss in metal are becoming serious problems, which considerablely limits the data processing speed and causes high energy consumption. This drives the motivation of scientists to design efficient all-optical switches where one light controls another, which in priciple may avoid the physical limitations of metalic wires.

In this project, you will be investigating a cavity-waveguide system based on photonic crystal membrane platform which supports two Fano resonances. One resonance will be used for controlling the other resonance. The steep slope of Fano resonances makes it possible for extremely efficient all-optical switching on photonic chip. Recently, the interesting physics of Fano resonance enabled experimental demonstration of ultrafast optical switches [1] and self-pulsing nanolasers [2].

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
