<p>The present device includes a laser cavity (1) having a laser amplification zone (2) and a saturable absorption zone (3). An asymmetric coupling device (4) includes a first (6) and a second (5) light guide having, for the laser emission wavelength of the cavity, different effective refractive indices, the effective index of the said first guide (6) being at least close to the effective index of the laser mode propagating in the said amplification and absorption zones, the said second guide (5) being configured so as to be able to be coupled with a source of optical command signals. The invention applies to optically triggerable laser devices serving, for example, as bi-stable photon operator, optical regenerator element and element of a shift register or optical delay line with multiple outputs. <IMAGE></p> |
