A novel optical power monitoring method based on optoelectronic oscillators incorporating semiconductor optical amplifiers is presented and a prototype of two nodes distributed online optical power monitor with dynamic measuring range of 6dB and accuracy of 0.25dB is experimentally demonstrated.
We introduce an optically controlled microwave phase stabilizer based on polarization interference technique using single
semiconductor optical amplifier (SOA). A prototype with a frequency of 10 GHz is experimentally demonstrated. It
provides a stable phase drift that can be linearly compensated over 10 km single-mode fiber by controlling the SOA injection
We introduce an optical delay line based on the nonlinear birefringence effects in a polarization-maintaining fiber Bragg grating (PMFBG). A 92 ps delay (approximate 360° phase shifts at 10 GHz) is demonstrated with independent of the optical wavelength drifting by tuning the polarization angle of the polarization controller (PC) from 0 to 90°.
