A new magnetic resonance imaging (MRI)-compatible positron emission tomography (PET) detector design is being developed that uses electro-optical coupling to bring the amplitude and arrival time information of high-speed PET detector scintillation pulses out of an MRI system. The electro-optical coupling technology consists of a magnetically insensitive photodetector output signal connected to ...

We use optical rectification and electro-optic sensing to generate and detect terahertz radiation, using individual and multilayered stacks of electro-optic polymer films. For comparable thickness, the polymer films are more efficient generators and detectors of terahertz radiation than ZnTe crystals.

We discuss recent results in low-energy (0.9fJ/bit) high-speed (25Gb/s) electro-optically stabilized microdisk modulators. The combined results of highly efficient modulation and electro-optic thermal compensation represent a major step towards single-digit femtojoule-class communications. ©2014 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (230.5750) Resonators; ...

The nonlinear dynamic behavior of a direct frequency-modulated diode laser with strong optical feedback is examined and compared to a laser diode subject to electro-optically modulated, strong optical feedback. Direct modulation is achieved by sinusoidal modulation of the diode laser injection current. Electro-optic modulation is achieved by applying a sinusoidal voltage to an intracavity phase...
