SOB-03 - Harmonic mode locking in multi-wavelength Fabry-Perot lasers - Tyndall National Institute
The photonics theory group has developed an inverse problem solution that enables the increase of the effective free spectral range in a Fabry-Perot laser for a fixed device length.
By incorporating a saturable absorber section in the device, mode locking can occur with repetition rates in the THz region.
The control of the mode structure can also in principle enable the tailoring of the generated pulse shape.
This project will involve device design as well as experimental inputs and will proceed with collaborators at Dublin City University, who will precisely characterise the mode locked state in the device.
The ultimate goal is to optimise devices for optical clock generation and pulse retiming in future ultrafast optical networks.
