Detuned loading effect
WebDetuned loading in directly modulated DBR lasers has been evaluated. IMD3 was measured, yielding a spurious free dynamic range of >103 dB/Hz/sup 2/3/ for fre … WebNov 1, 2013 · The effect of phase-sensitive optical feedback is directly visible from Fig. 2, ... Detuned loading is realised in a coupled cavity laser system by coupling a passive cavity to the active semiconductor laser such that frequency-dependent losses with a periodicity of the free-spectral range of the passive cavity are introduced.

Designs and recent progress are discussed to inspire future research.
WebJun 23, 2024 · The effect of detuning is not only due to a change in effective linewidth enhancement factor, but also due to a change of the effective cavity length. The results can be applied also to laser... Webponential term. This effect can be explained as the cancel-lation among the dipole modes, so that the sum of the wake looks small, but it is not damped at all. In a reality, the number of modes is finite, so that the cancellation is not perfect. After some period, the detuned modes are re-synchronized and the amplitude of the sum
