Abstract

Superoscillatory functions are characterized with local oscillations which are faster than the highest Fourier components in the spectrum of the function Such function gathered interest with the birth of quantum weak measurements in the late 1980s while in optics a surge of interest emerged in recent years with emphasis on using superoscillations for super resolution microscopy Several works utilizing optical super oscillations in different scenarios would be reviewed We ll discuss a theoretical suggestion to use temporal superoscillations to achieve super transmission delivery of very fast oscillations through absorbing dielectric materials Then we ll present experimental results of synthesizing an ultrafast optical pulse with a superoscillating envelope breaking the temporal focusing limit associated with transform limited pulses We ll discuss the option to use such signals to realize temporal super resolution measurements Finally we show how a set of Airy beams can be combined together to realize a super oscillating Airy pattern with interesting features such as chirped superoscillations and self healing
