“…The monolithic integration of two DFB lasers and an optical combiner has been a common solution, either with a Y-junction [59], [60] or MMI coupler. An important detail of such integrated schemes is that a reduction in the free-running beat-note linewidth can be achieved increasing the length of the lasers [61]. It has been demonstrated that devices with 2500 μm cavity length exhibit a minimum full-width half maximum (FWHM) linewidth of less than 300 kHz, which was sufficient to establish a 1 Gbit/s ASK data transmission wireless link with the two wavelengths in a free-running state generating a 146-GHz carrier wave [14].…”

SUMMARYThis paper reviews a recent progress in terahertz wireless communications enabled by photonics technologies. After briefly summarizing transceiver configurations with electronics and photonics technologies, photonics-based approaches to achieving over 100-Gbit/s data rates are discussed. Then, some of our updated results on real-time wireless transmission experiments using discrete components are shown at data rates up to 50 Gbit/s. Finally, integration technologies are described by demonstrating latest advances in integrated optical sources and transmitters.

“…Manuscript In our previous published works high bandwidth UniTraveling Carrier Photodiodes (UTC-PDs) compatible with active/passive integration were demonstrated [2]. We have also demonstrated monolithic integration of two narrow linewidth DFB lasers with passive optical waveguides and couplers [4]. In this letter we demonstrate active/passive integration that allows Distributed Feedback (DFB) Lasers, Semiconductor Optical Amplifiers (SOAs), electro-optical modulators, Multimode Interference (MMI) couplers and high speed UTC-PDs on the same chip.…”

A monolithically integrated tunable heterodyne source designed for the generation and modulation of subterahertz signals is demonstrated. Distributed feedback lasers, semiconductor optical amplifier amplifiers, passive waveguides, beam combiners, electro-optic modulators, and high-speed photodetectors have been monolithically integrated on the same InP-based platform. Millimeter wave generation at up to 105 GHz based on heterodyning the optical tones from two integrated lasers in the integrated high bandwidth unitraveling-carrier photodetector has been demonstrated. This photonic integrated chip was used in a 100-Mb/s OOK wireless transmission experiment using the integrated amplitude modulator.

“…One approach is based on the monolithic integration of distributed feedback (DFB) lasers, where two DFB lasers were grown side by side and the wavelengths combined using a Yjunction [11]. This approach is compact and both lasers encounter the same environmental fluctuations, thus reducing noise in the heterodyne signal.…”

“…A major advantage of this design is that it provides continuous tuning of wavelength spacing between the two monolithically integrated DFB lasers, with tuning of the mm-wave signal over the frequency range from 5 GHz to 110 GHz demonstrated. However, its drawback is the relatively broad line-width of the optical modes (> 300 kHz) [13].…”

Optical fibre transmission has enabled greatly increased transmission rates, with 10 Gb/s common in local area networks. End users find wireless access highly convenient for mobile communication. However, limited spectrum availability at microwave frequencies results in per-user transmission rates limited to much lower values, 500 Mb/s for 5 GHz band IEEE 802.11ac, for example. Extending the high data-rate capacity of optical fibre transmission to wireless devices, requires greatly increased carrier frequencies. This paper will describe how photonic techniques can enable ultra-high capacity wireless data distribution and transmission using signals at millimetre-wave and TeraHertz (THz) frequencies.
