We demonstrate optical up-conversion with frequency quadrupling using an optical phase modulator and a flat-top silicon microresonator filter by beating two second order sidebands at photodetector. 14 GHz signal was achieved using 3.5 GHz RF components.
We experimentally demonstrated millimeter wave generation using four-wave-mixing (FWM) in silicon nanowire waveguide. By filtering the central carrier in the second order FWM, two coherent sidebands beating at photodetector generated 40 GHz RF tone.
We demonstrate an optical wired and wireless access network using wavelength-splitting (WS) at remote-node. A pair of CW carriers is generated from each laser source for wired and wireless applications respectively for effective Rayleigh-backscattering mitigation.
In this paper we propose and demonstrate a technique for multi-channel optical mm-wave signal generation by frequency quadrupling. By setting the DC bias of a Mach-Zehnder electro-optic modulator (MZM) to its transmission maximum, second order sidebands are generated while the first order sidebands can be suppressed. In addition to the two peaks of the second order sidebands, the output of the MZM...
We demonstrate a bidirectional ROF system using a separate optical-clock distribution to mitigate signal-fading and code time-shifting. Error-free signal remodulation using downlink DPSK and uplink OOK was achieved in a 20-km reach ROF system.
It is demonstrated experimentally that the frequency chirp of a data modulated signal can be reduced and the modulation bandwidth increased through wavelength conversion in an electroabsorption modulator.
