“…However, the complexity of the scheme [19] makes it unlikely to evolve into a commercial product. A more recent implementation of spectral phase conjugation using two time-lens fiber systems and four-wave mixing in silicon waveguides has been demonstrated for picosecond pulses propagating in optical fibers [21].…”

Recently [Sivan and Pendry, Phys. Rev. Lett. 106, 193902 (2011)], we have shown that the wave front of short pulses can be accurately and efficiently reversed by use of simple one-dimensional zero-gap photonic crystals. In this paper, we describe the analytical approach in detail, and discuss specific structures and modulation techniques as well as the required steps for achieving complete time reversal. We also show that our scheme is only very weakly sensitive to material losses and dispersion.

“…Modern time lenses use all-optical nonlinear parametric processes such as three-or four-wave mixing of the input signal with a chirped optical-pump pulse in a nonlinear crystal [6-10]. On the basis of such space-time duality, it is possible to transfer to the temporal domain a large variety of imaging schemes such as, for example, temporal magnification [5,11], time-to-frequency conversion [12], pulse compression [4,5,13], spectral expansion [14], or spectral phase conjugation [15].Until recently, spatial optical imaging has been ignoring the quantum nature of the light because the intensity of light was so high that quantum fluctuations were negligible. However, as the pixel size in digital imaging devices decreases, the amount of light per pixel can reach the level where the quantum fluctuations become important.…”

We generalize the scheme of conventional temporal imaging to quantum temporal imaging viable for nonclassical states of light. As an example, we apply our scheme to temporally broadband squeezed light and demonstrate a possibility of its noiseless magnification. In particular, we show that one can magnify by a given factor the coherence time of squeezed light and match it to the response time of the photodetector. This feature opens new possibilities for practical applications of temporally broadband squeezed light in quantum optics and quantum information.

“…While for the parametric mixer, stronger focusing capability (smaller focal GDD) was achieved, but the repetition rate was limited by the mode-locked lasers; regardless, it was implemented by the FWM in a silicon waveguide [30]. For example, a temporal filtering system can be constructed by two cascaded temporal Fourier transformers [31], which can be performed by the phase modulator [32] and the parametric mixer [33]. To give an overview about all these time-lens system based on the two aforementioned parameters, the focal GDD Φ f and the repetition rate f t (the time-lens effect actually occurs), here we summarize all these references into Fig.…”

Comparison of state-of-art phase modulators and parametric mixers in time-lens applications under different repetition rates

Ever since the discovery of space-time duality, several methods have been developed to perform temporal imaging, and there are two major categories: the quadratic signal onto the phase modulator and the parametric mixer with a linear chirped pump. The features of each mechanism have been thoroughly and quantitatively explored and optimized for certain kinds of applications, but a comparison of some key parameters, especially in the aspect of the repetition rate, is required. In this paper, we will first review the theoretical models and existing performance of these two mechanisms and, consequently, compare them quantitatively in different aspects: the focal group delay dispersion, the pupil size, the effective duty ratio, and the temporal numerical aperture. All these fundamental parameters are related to the repetition rate. The results obtained in this study would provide some important guidelines for the time-lens design, so as to be optimized in different kinds of applications with different repetition rate requirements, such as ultrafast optical communication and real-time bio-imaging systems.
