“…However, it has the disadvantages of narrow bandwidth. Much attention has been focused on improving the bandwidth of monopole antennas [1,2]. A monopole with an impedance bandwidth of 28% and ͉S 11 ͉ Ͻ Ϫ10 dB was obtained using double-sleeve technology [3].…”

“…Cascaded Mach-Zehnder electrooptical modulators (MZ-EOM) have been extensively employed as photonic mixers, both for fundamental [1][2][3] and harmonic [4,5] downconversion, in applications ranging from antenna remoting to CATV or local multipoint distribution system (LMDS) signal distribution. Recently, electroabsorption modulators (EAM) have been proposed to downconvert 60-GHz signals to an S-band intermediate frequency (IF) [6,7] using direct fundamental mixing.…”

Two harmonic photonic-downconversion schemes employing electroabsorption modulators are proposed and experimentally demonstrated. Harmonic downconversion of 34-Mb/s data modulated onto a 9.5-GHz signal has been performed using (i) a single electroabsorption modulator, (ii) a Mach-Zehnder modulator and an electroabsorption modulator in series. Error-free operation for both schemes is demonstrated after transmission of the IF signal through a 25-km fiber-opticlink for harmonic orders of up to three. The influence of the biasing point of the modulator on the overall performance of both photonic downconversion schemes is discussed.

“…A number of wideband microwave photonic signal processing techniques useful for defence applications have been developed [2][3]. These solutions have largely ignored signal orthogonality, as it is generally difficult to generate inphase (0 o ) and quadrature (90 o ) microwave signals over a wide bandwidth in the optical domain.…”

Future telecom satellite based on geo-stationary Earth orbit (GEO) will require advanced payloads in Kaband so as to receive, route and re-transmit hundreds of microwave channels over multiple antenna beams. We report on the proof-of-concept demonstration of a analogue repeater making use of microwave photonic technologies for supporting broadband, transparent, and flexible cross-connectivity. It has microwave input and output sections, and features a photonic core for LO distribution, frequency down-conversion, and cross-connection of RF channels. With benefits such as transparency to RF frequency, infinite RF isolation, mass and volume savings, such a microwave photonic cross-connect would compare favourably with microwave implementations, and based on optical MEMS switches could grow up to large port counts.
