“…In the system of time lens, the similarity of the signal's dispersion transmission and the diffraction of light are based on the effective ignorance of the nonlinear effects [1], high-order dispersion effect and the loss of the fiber. Figure 1 is a structural model of the time lens which is based on the spatial lens system.…”

“…In addition, in spatial optical processing, space lens can be viewed as a spatial phase modulator, and it provides a secondary phase modulation for space position variables, so people provide a secondary phase modulation for time variables using the similar principle of diffraction and dispersion transport. Similar to the spatial imaging systems, people set up a time imaging system and call it the time lens [1][2]. We know the space lens can achieve the function of compression and amplification imaging and spatial Fourier transform on the focal length of the light field.…”

Abstract. Using the similarity between the transmission of narrow band light pulses in the dispersion media and the transmission of spatial beam in paraxial diffraction, build a time lens system similar to the space lens. Space lens can achieve compression and amplification of imaging function, and it has the nature of Fourier transform in light field. Then the time lens can also realize the compression and amplification of the light pulse and its Fourier transform. Using the function of Fourier transform in the time domain of time lens system, achieved the effect of eliminating noise and removing side lobe, improved the white noise which generally exist in the communication system and the side lobe effect which will produce in the relevant processes.

The equations that govern the temporal evolution of two photons in the Schrödinger picture are derived, taking into account the effects of loss, group-velocity dispersion, temporal phase modulation, linear coupling among different optical modes, and four-wave mixing. Inspired by the formalism, we propose the concept of quantum temporal imaging, which uses dispersive elements and temporal phase modulators to manipulate the temporal correlation of two entangled photons. We also present the exact solution of a two-photon vector soliton, in order to demonstrate the ease of use and intuitiveness of the proposed formulation.

“…The reported systems depend on paraxial diffraction in space and dispersion in time being equivalent [7] so that a time version of a dispersive spatial lens can be constructed, a 'time lens', so-called because it works in much the same manner as a spatial thin-lens. A spatial lens imparts a quadratic phase in space and a time-lens produces a quadratic phase shift in time [8][9][10][11].…”

Abstract-Based on space-time duality and through the use of temporal dispersive delay lines, this paper presents a demonstration of temporal cloaking/uncloaking at microwave frequencies. Numerical simulations of pulse generation, continuous wave signal recovery and data recovery are discussed in relation to the proposed system architecture. This paper also suggests a practical means for implementation of real time dual temporal cloaking/uncloaking. Compared to traditional signal processing systems, since the recovered data emerges with a reversed form in time domain before its final decoding, an extra operation named time-reversal is needed to obtain the correct data, which could help protect the significant signals better with the proposed temporal cloaking/uncloaking system. The proposed method and achieved results indicate potential application in secure communications and data multiplexing subject to channel bandwidth requirements.
