LASER COMPONENTS would like to introduce its phase modulator especially designed to operate in the 1000nm wavelength band. The NIR-MPX series use a proton exchanged based waveguide process that ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

LASER COMPONENTS would like to introduce our phase modulators especially designed to operate in the 1000nm wavelength band. The NIR-MPX series uses a proton exchanged based waveguide process that ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Engineers have invented a breakthrough optical phase modulator that controls visible light -- without dimming it -- with the smallest footprint and lowest power consumption. New device will improve ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Eliminating software adjustments in circuits based on digital logic improves robustness and reduces cost for small-production-run series. This circuit is a cost-improved version of classical QPSK ...

Can γ-secretase modulators stage a comeback? Scientists led by Irene Gerlach at F. Hoffmann-La Roche, Basel, Switzerland, are banking on it. At this year’s CTAD meeting, held October 24-27 in Boston, ...

In the last few years, several technology companies including Google, Microsoft, and IBM, have massively invested in quantum computing systems based on microwave superconducting circuit platforms in ...
