DOI: 10.1088/1612-202x/ae1e69
Abstract: Microwave-to-optical conversion is essential for connecting superconducting quantum processors with optical quantum networks, but detecting weak input signals typically requires operating in the strong-coupling regime with large cooperativity, which imposes stringent experimental constraints. We propose… read more here.

DOI: 10.1364/ol.44.004127
Abstract: Hollow core optical fibers are normally passive light transport components. In contrast, within this Letter, we numerically investigate the possibility of using them as optical amplifiers, through the adoption of a novel fiber structure. We… read more here.
