Photonic-based integrated sources and antenna arrays for broadband wireless links in terahertz communications. Semiconductor Science and Technology, 34(5), 054001.0268-1242http://hdl.handle.net/10016/36466This paper analyzes integrated components for ultra-broadband millimeter-wave wireless transmitters enabling the 5 G objective to increase the wireless data rates 10x to 100x . We have pursued the photonic-based approach to generate the millimeter-wave carrier (approximate to 97GHz in this paper) through photomixing. We have achieved up to 10 Gb s(-1) data rate using an OOK modulation format (to reduce latency) and either direct detection (DD) or coherent detection. We show that coherent detection enables a sensitivity improvement of 17 dB over DD. We also demonstrate in this work that such improvement can be achieved using as the transmitter a novel integrated antenna array-the self-complementary chessboard array. This avoids the use of complex coherent schemes at the receiver, enabling simple DD for ultra-broadband links.8eng© 2019 IOP Publishing Ltd.Atribución 3.0 EspañaPhotonic integrationPhotomixingDirect detectionCoherent detectionWireless linksMillimeter-waveAntenna arraysGenerationSignalsresearch articleElectrónicaTelecomunicacioneshttps://doi.org/10.1088/1361-6641/aaf8f2open access15(054001)8Semiconductor Science and Technology34AR/0000023496
