| 摘要 |
The structure (1) has an optical cavity of geometrical thickness (L) given by an expression involving the parameters of wavelength (lambda ) of an incident optical signal and effective index (n eff) of the cavity, where the cavity has an active layer (2). The amplitude dynamic of the incident signal and the thickness (L) are such that a maximum absorption variation (delta alpha ) verifies a relation involving the thickness (L) and Henry factor (alpha h) parameters. Parabolic mirrors (3, 4) are disposed on both sides of the layer. An independent claim is also included for an optical signal regenerator comprising an optical saturable absorbing structure. |
