By using a cascaded optical RF and data modulation approach with advanced photonic components as well as radio-over-fiber (RoF) transmission and simple NRZ-OOK modulation format, the system allows flexible adjustment of the wireless RF carrier frequency within the 75-110 GHz (W-band). In first experiments, error-free wireless transmission of 1 Gb/s and 1.25 Gb/s for a wireless span of 2 m has been achieved. The maximum system's data rate of 2.5 Gb/s is limited by the wireless receiver bandwidth. Wireless experiments were carried out in a lab environment up to 2.5 m span using a passive, i.e. amplifier-less W-band RoF wireless transmitter with an EIRP of 21 dBm. The passive RoF transmitter is composed of a high-power broadband InGaAs photodiode and a 21 dBi gain horn antenna.

The extinction of the filter notch is tuned with micro-heaters, by setting the Mach-Zehnder coupler of the ring. Experimental results showing a modulation depth improvement of up to 20 dB are provided.

The etch rates are characterised by varying the angle of incidence of the beam onto the substrate. Ta 2 O 5 gratings with a period of 2.2 mm (1.1 mm linewidth) and 0.25 mm thickness are fabricated using an angle of incidence of 08. The resulting Ta 2 O 5 grating cross sectional profiles are analysed using AFM and SEM imaging. A fabrication method is thus demonstrated which could be used to implement wavelength selective gratings in applications such as grating-assisted directional couplers (GADCs). #

The different functions required of optical node were demonstrated using interferometric technique with the extraction, drop, and addition of individual sub-channel in a ten subchannels optically aggregated signal. The scheme we report enables a fully flexible node compatible with future terabit/s superchannel transmission.
