For many scientific, commercial, and industrial uses, ultrafast lasers constitute the source of choice. Materials with non-linear optical properties are needed for this. The key requirements for non-linear materials are fast response time, strong non-linearity, broad wavelength range, low optical loss, high power handling, low power consumption, low cost and ease of integration into an optical system. The current solutions do not meet all these requirements. Recent advances in nanotechnology however, have the potential to overcome many of the shortcomings of traditional semiconductor technology. Graphene and carbon nanotubes show high promise for optical device technology. They can be placed on glass, quartz, silicon and other substrates suitable for optoelectronic integration. The aim of the project is to build and test a nanotube/graphene ultrafast fiber laser. The operation wavelength of the ultrafast laser is around 1.5um, the fiber optical telecommunication spectral range.

Task

1. Fabricate graphene/nanotubes based nonlinear optical devices. 2. Integrate graphene/nanotubes based nonlinear optical devices into a fiber laser 3. Characterize the ultrafast laser

Requirements

1. Interested in re-search. 2. Prior courses in fundamental physics (e.g., Electromagnetic Fields and Waves, photonics, Optoelectronics). 3. Willing to work in a Clean-Room.
