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 manipulation 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
