Linear photonic radio frequency phase shifter using a differential-group-delay element and an optical phase modulator.

چکیده
We demonstrate a stable and linear photonic radio frequency (RF) phase shifter based on a differential-group-delay element and the polarization sensitive effect of an optical phase modulator. The phase shift can be tuned continuously over 360 degrees for RF signals over 40GHz with an electrical control voltage from -7.5 to +7.5V.

Effect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملPhotonic microwave phase shifter/modulator based on a nonlinear optical loop mirror incorporating a Mach-Zehnder interferometer.
We realize a novel photonic microwave phase shifter/modulator based on a nonlinear optical loop mirror incorporating a Mach-Zehnder interferometer. A near-linear phase shifter exceeding 180 degrees and a phase modulation with 2.5 Gbit/s baseband signal are obtained for a 10 GHz microwave signal by this proposed device.
متن کاملContinuously Tunable Photonic Radio-Frequency Notch Filter - IEEE Photonics Technology Letters
We present a continuously tunable nonrecursive radio-frequency (RF) photonic filter. The filter provides fine tuning through the use of a novel RF phase shifter and coarse tuning using an all optical variable time delay. This architecture permits wide-band continuous tuning of the filter null frequency and is useful in applications such as moving target indication (MTI) in an airborne radar.
متن کاملA Novel Π - Phase Shifter in Integrated Optics
The Integrated Optics has resulted in miniaturization of optical devices. Bent waveguides have replaced straight waveguides in optical integrated circuits for such reasons. In the proposed work, curved/bent waveguide is basic structure for generating delay and hence the phase shift. A differential phase shift is obtained by the differential length change between the straight waveguide and a S-b...
متن کاملBroadband photonic microwave phase shifter based on controlling two RF modulation sidebands via a Fourier-domain optical processor.
An all-optical photonic microwave phase shifter that can realize a continuous 360° phase shift over a wide frequency range is presented. It is based on the new concept of controlling the amplitude and phase of the two RF modulation sidebands via a Fourier-domain optical processor. The operating frequency range of the phase shifter is largely increased compared to the previously reported Fourier...
