1965: The first issue of Electronics Letters presents a discussion of colour television system parameters. UK researchers argue that the present system is too complicated, particularly when looking forward to the possibility of a unified European carrier-modulation and to a time when picture quality is not limited by instrumentation inadequacies.
1975: The translinear principle is defined by Barrie Gilbert, introducing the world to translinear circuits and elements. The principle allows exponential current-voltage transistor circuits – such as CMOS and BJTs – to operate as multipliers or amplifiers, and also provides more effective analysis of such circuits.
Lighter and faster
1985: The first all-silicon integrated optical components are developed by US researchers, creating the world of silicon photonics. Optical interconnects have a significant effect on the speed of communications systems and the possibilities for monolithic integration of optics and microelectronics.
1999: Researchers at Bell Labs in the US describe a simplified version of the BLAST detection algorithm, known as vertical BLAST, or V-BLAST. Using their laboratory prototype, they effectively eliminate interference caused by successive issuers, with spectral efficiencies as high as 40bit/s/Hz in an indoor environment.
Covering the field
2000: In the new millennium, Electronics Letters continues to offer multi-application research, with Amnon Yariv providing universal relations for coupling of optical power between microresonators and dielectric waveguides. By considering a generic dielectric waveguide coupled to a ring resonator, he describes the fundamental working equations for a vast range of devices.
