This paper presents an integrated tunable hybrid multi-laser module designed to simultaneously generate multiple radiofrequency (RF) local oscillator (LO) signals through optical heterodyning. The device consists of five InP/Si3N4 lasers, each incorporating intracavity wavelength-selective filter formed by two micro-ring resonators. Through beating the wavelengths generated from three these we demonstrate simultaneous generation LO within bands crucial for satellite communications (SatCom):...
An experimental investigation of diversity factors for CFLs (compact fluorescent lamps) in combination with LED (light emitting diode) lamps is presented this paper. Diversity were calculated different configurations connected to the same feeder one phase. It was found that presence a high apparent power input can lead considerable damping harmonics. If number much greater, effect as very low. Harmonic emission limits also analyzed. A conclusion has been made sufficient variety energy saving...

In modern buildings virtually all electric loads are non-linear. Neither the applicable standards for supply of electrical energy nor those consumption take into account replacement linear by non-linear loads. Low power equipment is exempted in assuming that other (linear) dominate quality. there a huge number lighting, monitor, computer and small supplies only very limited (or no) conventional This causing unacceptable interference with costly consequences. paper analyzes current...
