Phase-Only Temporal Mode Transformations with Complex Spectral and Temporal Phases

Jerzy Szuniewicz, Filip Sośnicki, Michał Karpiński

Spectral-temporal modes of quantum light have been recognized as a promising platform for quantum information processing (QIP) and metrology [1], [2]. However, a simple general tool for efficient conversion between spectral-temporal modes is still missing. A phase-only, i.e. in-principle lossless, approach is required for quantum light. The existing phase-only approaches for converting a given input spectral-temporal mode to a given target spectral-temporal mode rely on sequences of complex temporal phase modulations interleaved with propagation in second order dispersive medium, yielding complex setups with often formidable insertion losses. Here we show that such a transformation can be carried out by a single application of a complex temporal phase modulation, and a single application of complex spectral phase modulation.

Large-scale spectral bandwidth compression by complex electro-optic temporal phase modulation

Filip Sośnicki, Michał Karpiński

Spectral-temporal shaping of quantum light has important applications in quantum communications and photonic quantum information processing. Electro-optic temporal lenses have recently been recognized as a tool for noise-free, efficient spectral bandwidth manipulation of single-photon wavepackets. However, standard electro-optic time lenses based on single-tone modulation exhibit, limited bandwidth modification factors due to material limitations on phase modulation amplitude. Here we numerically investigate the use of complex electro-optic temporal phase modulation patterns for bandwidth compression of light over multiple orders of magnitude and show the feasibility of their use in photonic interfaces for quantum network applications.

Matter waves in time-modulated complex light potentials

Stefan Bernet, Roland Abfalterer, C. Keller +3 more

Temporal light modulation methods which are of great practical importance in optical technology, are emulated with matter waves. This includes generation and tailoring of matter-wave sidebands, using amplitude and phase modulation of an atomic beam. In the experiments atoms are Bragg diffracted at standing light fields, which are periodically modulated in intensity or frequency. This gives rise to a generalized Bragg situation under which the atomic matter waves are both diffracted and coherently shifted in their de Broglie frequency. In particular, we demonstrate creation of complex and non-Hermitian matter-wave modulations. One interesting case is a potential with a time-dependent complex helicity $[V\ensuremath{\propto}\mathrm{exp}(i\ensuremath{\omega}t)],$ which produces a purely lopsided energy transfer between the atoms and the photons, and thus violates the usual symmetry between absorption and stimulated emission of energy quanta. Possible applications range from atom cooling over advanced atomic interferometers to a new type of mass spectrometer.
