提出并演示了一种基于窄带相移光纤布拉格光栅(PSFBG)和激光器波长调谐的宽带频率可调谐光电振荡器(OEO)。在光学单边带调制器的帮助下,具有窄传输峰值的PSFBG就像等效的高Q微波滤波器一样来选择振荡频率。 OEO 的频率可调谐性可以通过调谐激光源的波长来简单地实现。产生了频率在8.4~11.8 GHz宽范围内可调的X波段光电振荡信号,并在实验中研究了其性能。
A wideband frequency-tunable optoelectronic oscillator (OEO) based on a narrowband phase-shifted fiber Bragg grating (PSFBG) and wavelength tuning of the laser is proposed and demonstrated. With assistance of an optical single-sideband modulator, the PSFBG with a narrow transmission peak acts like an equivalent high-Q microwave filter to select the oscillation frequency. Frequency tunability of the OEO can be simply realized by tuning the wavelength of a laser source. An X-band optoelectronic oscillating signal with frequency tunable at wide range from 8.4 to 11.8 GHz is generated and its performance is investigated in the experiment.
