This work presents the development of an optically controlled slot antenna, capable of operating at two different resonant frequencies, 2.5 GHz and 5.1 GHz. A silicon switch controls the frequency operation. The proposed antenna design was analyzed in terms of S-parameters and gain. Measured results show a difference of 20 dB for the reflection coefficient and 3 dB in the antenna gain, between the...
In this paper, we address the experimental implementation of an all-optical packet routing scheme, with contention resolution capability, using interconnected semiconductor optical amplifier (SOA)-based Mach?? Zehnder interferometer (SOA-MZI) structures. Cross talk stemming from the blocked packets, due to the nonideal switching performed by the SOA-MZIs, is analyzed in every stage of the routing...
We demonstrate 40Gb/s operation without bit loss of an all-optical selective wavelength-shifter in a SOA-MZI enabling simultaneous wavelength-conversion and data erasing of data burst under a gate signal.
