Ultrahigh-fidelity composite rotational quantum gates
Hayk Gevorgyan, Nikolay V. Vitanov
Composite pulse sequences, which produce arbitrary pre-defined rotations of a qubit on the Bloch sphere, are presented. The composite sequences contain up to 17 pulses and can comp…
Optical Isolation with Microring Modulators
Nathan Dostart, Hayk Gevorgyan, Deniz Onural +1
Optical isolators, while commonplace in bulk- and fiber-optic systems, remain a key missing component in integrated photonic systems. Isolation using magneto-optic effects has been…
Active-cavity photonic molecule optical data wavelength converter for silicon photonics platforms
Hayk Gevorgyan, Anatol Khilo, Miloš A. Popović
We demonstrate an optical data wavelength converter based on an electrically driven photonic molecule structure comprising two coupled active silicon microring resonators. The conv…
Triply-resonant coupled-cavity electro-optic modulators for on-chip RF photonic systems
Hayk Gevorgyan, Anatol Khilo, Yossef Ehrlichman +1
We propose a triply-resonant electro-optic modulator architecture which maximizes modulation efficiency using simultaneous resonant enhancement of the RF drive signal, the optical…
