Arbitrary polarization retarders and polarization controllers, constructed from sequences of half-wave and quarter-wave plates
Hayk L. Gevorgyan, Andon A. Rangelov
We theoretically introduce several types of arbitrary polarization retarders constructed from sequences of half-wave and quarter-wave plates, each rotated at specific angles. By in…
Broadband composite nonreciprocal polarization wave plates and optical isolators
Hayk L. Gevorgyan, Andon A. Rangelov, Nikolay V. Vitanov
We provide a technique for a broadband nonreciprocal wave retarder whose quarter-wave plate phase retardation is the same in forward and backward directions. The system is built us…
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…
Tunable Optical Radiation Formed in Crystalline Undulator
Hayk Gevorgyan
The problem of optical radiation produced by a bunch of relativistic positrons channeled to a crystalline undulator (CU) is considered. Taking into account the polarization of the…
