✦ Synopsis

Figure 5 Number of D-fiber antennas against minimum detectable phase shift

variation between the number of D-fiber antennas and the shot-noise-limited minimum detectable phase shift of the proposed network is shown in Figure 5. As can be seen from Figure 5, by increasing the number of D-fiber antennas, the level of minimum detectable phase shift increases, resulting in an overall decrease in network sensitivity.

V. CONCLUSIONS

The wide frequency response of an all-fiber optical antenna comprising a circular core D-fiber coated with a transversely poled piezoelectric material has been demonstrated. Finiteelement modeling was employed to compute the straininduced phase shift over the frequency range from 1 to 600 MHz. The FEA simulations predict a phase shift value of Ž . 0.00173 radrVrm in the high-frequency axially constrained region. At frequencies higher than 8 MHz, the optical response is dominated by radial resonances of the D-fiber coating composite. An antenna network has been analyzed using shot-noise-limited detection, which compares the relationship between number of D-fiber antennas and network sensitivity. Since the D-fiber antenna is constructed from totally dielectric materials, it can be used to receive radiofrequency transmissions without distorting or disturbing the field lines since there are no metallic components to reflect or transmit radio-frequency energy.
