Photonic integrated circuits that use light instead of electricity for computing and signal processing promise greater speed, increased bandwidth, and greater energy efficiency than traditional ...

Electrical engineers at the University of Rochester, NY, say they have made a significant step in addressing the problem of reducing the size of photonics integrated circuits enough to compete ...

Many applications require a circuit to perform pulse modulation and voltage amplification to drive a load with a train of impulses. A typical application is driving a piezoelectric generator in a ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...

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.

Electrical engineers have created the smallest electro-optical modulator yet, using a thin film of lithium niobate bonded on a silicon dioxide layer. This key component of a photonics-based chip ...
