High Speed Photonic Digital-To-Analog Conversion
A novel integrated optical modulator based on a multi-electrode Mach-Zehnder modulator has been developed at Tel-Aviv University. The device has superior performance in terms of linearity, dynamic range and implementation simplicity. These improvements are achieved by utilizing a unique mapping method between the analog input and the digital sequence applied to the device, and by […] Read More >
Direction of Arrival Deception Using Metasurfaces
The invention of radars was soon followed by extensive research and development of counter measures, the most well-known being the invention of stealth technology. By employing special geometric designs and carefully selected materials, a reduction of the target’s radar cross section and the resulting backscattered energy was successfully achieved, substantially reducing distances between the radar […] Read More >
LWIR / FIR / THz Detectors and Sources For High Sensitivity Remote Sensing
MIR-THz Detectors and Sources For High Sensitivity Remote Sensing The discoveries of novel materials and physical phenomena continuously drive technological advancements and their applications. So is the case for MIR-THz optoelectronics, operating roughly in the frequency range of f≈0.5-35THz. In this spectral range radiation penetrates through opaque materials without the risk of ionization, making MIR-THz […] Read More >
METHOD FOR GENERATION OF CONTROLLED THz WAVES
We present a method for the generation of THz pulses with tailored temporal shape from nonlinear metasurfaces. The method is based on single-cycle THz emission by the metasurface inclusions. We show that the spatial amplitude and phase structure of the nonlinear response is mapped to the temporal shape of pulses emitted at certain angles. We […] Read More >
