Tyndall National Institute: Epitaxy and Physics
Customer Use Application
The Epitaxy and Physics of Nanostructures (EPN) group at Tyndall National Institute, University College Cork, Ireland is using an X-LSM050A, one of Zaber's X-Series linear stages with a built-in controller, to build a long scan autocorrelator to characterise the pulse-width of a tuneable wavelength Ti:sapphire laser. Zaber's stage is part of a Michelson Interferometer where the pulse-width is measured as a power of a sum-frequency generation (SFG) signal vs. an optical delay. The set-up enables the fast characterisation of pulses with the width of tens of picoseconds. Precisely tailored pulse-width (typically in the range of a few picoseconds) is a critical parameter in resonant quantum dot excitation schemes.
About the Epitaxy and Physics of Nanostructures group at Tyndall National Institute
The EPN laboratory investigates the epitaxial growth mechanism and the physics of a variety of semiconductor structures. In particular, this group is undertaking fundamental studies of the growth mechanism and the optical properties of Pyramidal site-controlled quantum dots obtained by growing them in pre-patterned GaAs substrates. Their field of interest spans as far as optoelectronic and electronic devices, with special attention to light emitting sources at telecom wavelengths.
