An Alternate Spintronic Analog of the Electro-optic Modulator
There is significant current interest in spintronic devices fashioned after a spin analog of the electro-optic modulator proposed by Datta and Das [Appl. Phys. Lett., 56, 665 (1990)]. In their modulator, the “modulation” of the spin polarized current is carried out by tuning the Rashba spin-orbit interaction with a gate voltage. Here, we propose an analogous modulator where the modulation is ca...
متن کاملNear-infrared electro-optic modulator based on silicon- graphene hybrid structure
Graphene has strong electro-optic effect which can be used to enhance the modulation efficiency of nanoscale photonic circuit. This paper describes recent developments for nearinfrared electro-optic modulator based on silicon-graphene hybrid structure. OCIS codes: (070.6120) Spatial light modulators; (070.5753) Resonators; (350.4238) Nanophotonics and photonic crystals
متن کاملEnhanced electro-optic effect in GaInAsP–InP three-step quantum wells
We report on the enhanced electro-optic coefficient of GaInAsP three-step quantum wells ~3SQW! for high power electrorefraction modulator applications. Measured electro-optic coefficient of the 3SQW is nearly three times higher than the conventional rectangular quantum well ~RQW! at l51.55 mm. The enhanced electro-optic effect, combined with a low optical absorption coefficient a,1 cm in the 3S...
متن کاملHigh-q Microphotonic Electro-optic Modulator
A microphotonic mm-wave modulator using simultaneous RF and optical resonance in an electro-optic medium is presented. Theory and simulation of modulator operation is discussed, and experimental results demonstrating modulation using simultaneous resonance in the mm-wave range are reported.

متن کاملImproved performance of traveling wave directional coupler modulator based on electro-optic polymer
Polymer based electro-optic modulators have shown great potentials in high frequency analog optical links. Existing commercial LiNibO3 Mach-Zehnder modulators have intrinsic drawbacks in linearity to provide high fidelity communication. In this paper, we present the design, fabrication and characterization of a traveling wave directional coupler modulator based on electro-optic polymer, which i...
