- A 5-cm-long electrically tuned fiber Bragg grating is used to filter a microwave signal on an optical carrier at 1.55 µm. A chirped distributed-feedback structure is employed, with a transmission bandwidth of 54 MHz and relative optical carrier rejection of >30 dB for rf frequencies >2 GHz. The rapid monotonic sweep of the Bragg wavelength is translated into a fast-frequency sweep for rf analysis.

- A novel dual-polarization fiber laser is proposed by incorporating a distributed feedback grating inscribed in a twin-hole fiber with internal electrodes. Dual-polarization lasing is achieved with a spectral separation of 42 pm. By beating the optical waves at a photodiode, a microwave signal at 5.244 GHz is achieved with a signal-to-noise ratio 45 dB. An electrically tuned microwave signal with a tunable range of 150 MHz is demonstrated.
