Direct measurement of cross-phase modulation in microresonators
European Quantum Electronics Conference, 2019•opg.optica.org
The Kerr effect in microresonators is usually masked by thermal effects [1], as resonances
can thermally drift on the order of a few GHz, compared to Kerr effect shifts of a few MHz.
However, the Kerr effect, and in particular cross-phase modulation (XPM), is responsible for
important effects seen in microresonators. For instance, it can be indirectly observed in
solitons [2], as well as being the primary mechanism driving symmetry breaking of counter-
propagating light in microresonators [3–5]. By direct measurement, the effective mode area …

Abstract
The Kerr effect in microresonators is usually masked by thermal effects [1], as resonances can thermally drift on the order of a few GHz, compared to Kerr effect shifts of a few MHz. However, the Kerr effect, and in particular cross-phase modulation (XPM), is responsible for important effects seen in microresonators. For instance, it can be indirectly observed in solitons [2], as well as being the primary mechanism driving symmetry breaking of counter-propagating light in microresonators [3–5]. By direct measurement, the effective mode area can also be extracted by measuring the XPM-induced resonance shift.
