A direct modulation bandwidth of 66 GHz has been achieved from two daisy-chained VCSELs, and the principle could be scaled up to reach over 100 GHz. An international research team has shown that a ...

In many ways, high-speed optical communications are following the path that wireless technology has blazed. Of course, optical and wireless networks use different technologies to deal with specific ...

Reflective Semiconductor Optical Amplifiers, also known as RSOAs, are high-performance, low-cost transceivers used for data amplification and modulation in radio over fiber systems, full-duplex optic ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

Quantum wells are thin layered semiconductor structures that derive most of their properties from the quantum confinement of charge carriers (electrons and holes) in thin layers of a semiconductor ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...

BOSTON, Oct. 16, 2025 /PRNewswire/ -- spectralDSP Corporation today confirms the global revocation of unauthorized access to proprietary waveform enhancements, including Hyper-Scale Channel ...

The most basic characteristic of a Voltage Controlled Oscillator (VCO) is the manner in which the oscillator changes frequency as a function of voltage applied to its tuning port. As the state of the ...
