Capturing Arbitrary Waveform without Absorption with Synthesis of Complex Frequencies
Zhaohua Tian, Yu Tian, Yadi Niu +5
An arbitrary optical waveform can be synthesized by complex-frequency waves as well as by realfrequency harmonic waves. While single complex-frequency wave with exponentially risin…
