“…Optical techniques are beneficial in terms of wide working bandwidth and immunity to EMI, so switching of RF signals in the optical domain can potentially overcome electronic limitations. For instance, optical switch matrices based on SOAs [79], [80] can be applied to optical RF switching. Although the nanosecond-level rising or falling time supported by SOAs can ensure a high switching speed, a large number of SOAs must be implemented in the switching matrix, making the system complicated, costly, and power consuming.…”

The electro‐optical switching performances of four semiconductor optical amplifiers are compared. Devices with distinct physical features, using different pulse formats for the current injection, were evaluated experimentally. The wide range of results might help in indicating preferable devices and pulse formats for a particular application. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1500–1503, 2015

We propose an approach for dynamic channel allocation and multicast data delivery inside the 60 GHz unlicensed band. Channels, conveying 1.25 Gbps signals, can be allocated on demand by tuning the frequency sweep of an external cavity laser (ECL) either in the optical remote node (RN) or in the central office (CO). At the RN, we perform the replication of the original channel suitable for closely spaced multicast applications such as high definition (HD) video delivery where RN serves as a photonic radio frequency (RF) generator for both channel allocation and multicast. Experimental demonstration is presented with bit error rate (BER) performance below 10 -9 for original and replicated channels after transmission through 22.8 km of standard single mode fiber (SSMF).Index Terms -microwave photonics, Radio-over-Fiber (RoF), hybrid fiber wireless transmission, wireless distribution.
