Title: Controlling the Amplitude and Phase Profiles of Ultra-short Optical Pulses

Abstract: Ultra-fast optical pulses with durations ranging from hundreds of picoseconds to femtoseconds are used in an increasing number of industries, from manufacturing to telecommunications. Controlling the amplitude and phase profiles of these pulses is a vital aspect for optimizing both performance and cost minimization. Typically commercial pulse shapers use liquid crystal on silicon spatial light modulators, but these are free space components which reduce environmental stability. Recently, the increasing electrical bandwidth available to electo-optical modulators have enabled new pulse shaping techniques to be investigated.

The main objective of my research is to shape the amplitude and phase profiles of ultra short optical pulses using a Temporal Pulse Shaping System (TPSS). An IQ modulator will be used as an amplitude and phase modulator, which to date has not been established in either academic literature or industry. In my talk I will present the basics of a TPSS, and investigate using an IQ modulator in such a system. Initial simulations.
