Pulse shaping using a space-to-frequency-to-time mapping technique

Summary form only given. We present a new, simple and direct approach to synthesize arbitrary pulse shapes. The approach simply requires reflecting the input signal from an appropriately designed apodized linearly chirped fiber Bragg grating (ALCFBG). With current fabrication technology, our proposed technique allows the synthesis of pulse shapes with (i) resolutions of order of 10- 100 fs and (ii) durations only limited by the grating length (up to nanoseconds).
