Abstract

We demonstrate and experimentally evaluate electro-optic strategies for single-photon spectral bandwidth modification by more than 2 orders of magnitude, into sub-GHz regime. The results will enable photonic quantum network interfaces.

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.

Efficient Interface between Ultrafast and Nanosecond Optical Quantum Systems

Filip Sośnicki, Michał Mikołajczyk, Ali Golestani +1 more

A promising approach to realize a quantum internet [1] is to use a hybrid quantum network - a network composed of many different quantum devices, such as quantum emitters, quantum repeaters, or quantum gates, interconnected via photonic links. However, such a wide variety of quantum devices tends to be spectrally incompatible. Especially, the challenge arises to interface different single-photon spectral bandwidths with high efficiency. In particular, an important link is bridging the ultrafast optics with hundreds of GHz spectral bandwidths with nanosecond timescales of single-photon pulses, hence MHz-wide spectra. Such an interface corresponds, e.g., to coupling a single photon produced in a commonly used bulk spontaneous parametric down-conversion (SPDC) photon sources to atomic-based quantum memories. The already demonstrated spectral compression techniques, based mostly on optical nonlinearities, operate only in the above GHz regime and are not suitable for this task [2].
