Abstract
A high speed and efficient linear optical intensity modulator has been previously introduced. The linear transfer function of this modulator is inherent in the design of this modulator which stems from the arcsine phase response of an injection-locked resonant cavity with gain placed in one arm of a Mach-Zehnder interferometer. T = 1/2 (1 + cos (arcsin (f(t))- π/2) = 1/2 (1 +f(t)) Eq.1. In this paper, we present a measured spur-free dynamic range (SFDR) of an analog link employing this linear modulator. Link SFDR of ~101 dB.Hz <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2/3</sup> is achieved by locking the bias point of the all-fiber Mach-Zehnder interferometer at quadrature. It should be noted that no linearization technique is used.
