Out-of-loop measurements of f LT and f bT. (a) Linewidth distribution of 1000 groups of the f LT (dots) and its Lorentzian fit (solid curve) when the RBW of the FFT spectrum analyzer is 0.5 Hz. The inset shows the Allan deviation of f LT (dots). (b) Linewidth distribution of 700 groups of the f bT (squares) and its Lorentzian fit (solid curve) when the RBW of the FFT spectrum analyzer is 0.5 Hz. The inset shows Allan deviation of f bT (triangles).
