A sound amplification technique from SLS Loudspeakers (Springfield, MO) promises to reduce the size and cost of high-power, professional quality speakers. The approach, dubbed Evenstar, uses a pair of ...

“Photon Design's next-generation, EPIPPROP simulator, will offer the flexibility to split waveguides, simulating this process ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

Innovation paves the way for a high-volume, silicon photonics 400G/lane platform to meet next-generation 3.2T optical communication architectures for datacom and AI applications. The integrated ...

OpenLight and Tower Semiconductor have announced a successful demonstration of a 400G/lane modulator on Tower's silicon photonics platform, PH18DA, which achieves over a 3.5dB extinction ratio using ...

Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they need to have the same color — or frequency — and bandwidth. Changing a photon’s ...

Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been used in a variety of ...

CML Microcircuits unveiled a new I/Q modulator in its family of RF integrated circuits. The CMX993 is a highly integrated, general-purpose RF quadrature modulator that operates between 100 MHz to 1 ...

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 ...

Recently, researchers have developed an integrated electro-optic modulator that can efficiently change the frequency and bandwidth of single photons. The device could be used for more advanced quantum ...
