Rapid reconfiguration direct space-to-time pulse shaping using a high speed asymmetric Fabry-Perot quantum well modulator array
Abstract
Optical pulse shaping has been a useful tool for creating user defined optical waveforms for various applications. However, pulse shaping is often limited by fixed masks or the slow switching speeds of commonly used opto-electronic modulators used as spatial profiles within these experiments. These masks and modulators assist in performing the transformation of a short optical pulse into a desired waveform, but their properties do not change between input pulses when a high repetition rate input source is used. The ability to rapidly reconfigure the spatial profile within the pulse shaper would allow the possibility of shaping to occur on an input pulse-by-pulse basis. For our solution, we turn to the asymmetric Fabry-Perot quantum well modulator for its high-speed functionality and optical bandwidth capabilities. An array of such devices could provide a quickly changing spatial profile that would enable rapid reconfiguration. Device design, fabrication, and testing will be addressed along with pulse shaping experiments and results.
