Abstract
Sonogram encoding is utilized to measure ultrafast optical pulses at 1550 nm. The optical waveform is divided into narrow-bandwidth frequency bins, which are time multiplexed. The recombined single-shot sonogram signal is acquired using high bandwidth electronics and processed to recover the pulse intensity and phase. Measurement of optical pulses with a variety of phase distortions introduced using a pulse shaper or dispersive optical fiber is demonstrated. One sonogram is acquired within less than 1 microsecond, which allows single-shot pulse measurement at a rate of up to 1 MHz. Capabilities and detailed specifications of the method will be presented.
