Electro-optic non-reciprocal polarization rotation in lithium niobate
Oğulcan E. Örsel, Gaurav Bahl
Polarization is a fundamental degree of freedom for light and is widely leveraged in free space and fiber optics. Non-reciprocal polarization rotation, enabled via the magneto-opti…
Electrically driven linear optical isolation through phonon mediated Autler-Townes splitting
Donggyu Sohn, Oğulcan E. Örsel, Gaurav Bahl
Optical isolators are indispensible components in nearly all photonic systems as they help ensure unidirectionality and provide crucial protection from undesirable reflections. Whi…
Observation of trapped fractional charge and topological states at disclination defects in higher-order topological insulators
Christopher W. Peterson, Tianhe Li, Wentao Jiang +2
Topological crystalline insulators (TCIs) can exhibit unique, quantized electric phenomena such as fractional electric polarization and boundary-localized fractional charge. This q…
A fractional corner anomaly reveals higher-order topology
Christopher W. Peterson, Tianhe Li, Wladimir A. Benalcazar +2
Spectral measurements of boundary localized in-gap modes are commonly used to identify topological insulators via the bulk-boundary correspondence. This can be extended to high-ord…
Trapped state at a dislocation in a weak magnetomechanical topological insulator
Inbar Hotzen Grinberg, Mao Lin, Wladimir A. Benalcazar +2
Topological insulators (TIs) are characterized by an insulating bulk and symmetry protected bound state on their boundaries. A "strong" topological insulator is characterized by ro…
Direction reconfigurable non-reciprocal acousto-optic modulator on chip
Donggyu B Sohn, Gaurav Bahl
Non-reciprocal components are essential in photonic systems for protecting light sources and for signal routing functions. Acousto-optic methods to produce non-reciprocal devices o…
