Abstract: In this article, a highly sensitive fiber Bragg grating (FBG) axial strain sensing system based on dual loop optoelectronic oscillator (OEO) enhanced by harmonic Vernier effect is proposed ...
Abstract: In this work, we investigate, for the first time, a low phase noise and wide tuning range voltage-controlled surface acoustic wave oscillator (VCSO) based on a lithium niobate on sapphire ...
