Photonic aided vector millimeter-wave signal generation without digital-to-analog converter

چکیده
A novel scheme of photonic aided vector millimeter-wave (mm-wave) signal generation without a digital-to-analog converter (DAC) is proposed. Based on our scheme, 20 Gb/s 4-ary quadrature amplitude modulation (4-QAM) mm-wave generated using DAC. The experiment results demonstrate that the bit error rate (BER) 4-QAM can reach below hard-decision forward-error-correction threshold after delivery over 1 m wireless distance. Because DAC not required, it reduce system cost. Besides, by technology, easily integrated to create large-scale production and application in high-speed optical communication.

Generation of millimeter-wave electronic signals and power is required for highfrequency communication links, RADAR, remote sensing and other applications. However, in the 30 to 300 GHz mm-wave regime, signal sources are bulky and inefficient. All-optical generation of mm-wave signals promises to improve efficiency to as much as 30 to 50 percent with output power as high as 100 mW. All of this ...

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
