A surface-emitting optical amplifier (10) having a generally circular waveguide (30) and active region (20). The waveguide (30) and active region (20) match the shape of an optical fiber or other device for generating, transmitting, guiding, propagating, etc., an optical signal. For example, the shape of the waveguide (30) and active region (20) may be circular, elliptical, square, rectangular, or virtually any other required shape. By matching the shape of the waveguide (30) and active region (20) to the shape of the device to which the waveguide connects, coupling loss is reduced and polarization dependent loss is eliminated due to the symmetry of the active region. The reduction of the coupling loss also leads to an increase of the signal to noise ratio since the signal loss from the input coupling is directly reduced.

Cet amplificateur optique à surface émettrice (10) comprend un guide d'ondes généralement circulaire (30) ainsi qu'une région active (20). Le guide d'ondes (30) et la région active (20) correspondent à la forme d'une fibre optique, ou d'un autre dispositif, destiné à produire, transmettre, propager, etc., un signal optique. Par exemple, la forme du guide d'ondes (30) et de la région active (20) peut être circulaire, elliptique, carrée, rectangulaire, ou elle peut revêtir virtuellement n'importe quelle autre forme voulue. En faisant correspondre la forme du guide d'onde (30) et de la région active (20) à la forme du dispositif auquel le guide d'ondes se connecte, on diminue la perte de couplage, et on élimine la perte due à la polarisation, par suite de la symétrie de la région active. La réduction de la perte de couplage conduit également à une augmentation du rapport signal/bruit, étant donné que la perte du signal, à partir du couplage d'entrée, est directement réduite.
