英文摘要 | The present invention is a novel multiple laser diode structure and methodfor using such structures to optically isolate the light from the differentdiodes. The novel structure comprises a submount on which the individuallasing elements are mounted and a back facet monitoring plate coupled tothe submount. The back facet monitoring plate comprises a plurality ofoptically sensitive detectors that monitor the amount of laser lightemanating from the back facet. Ideally, one detector should be mountedopposite a back facet for each lasing element. The submount is designedwith an isolation bar that optically separates the light from individuallasing elements. The radiation thus detected by each detector emanatesfrom the back facet of a single lasing element. The amount of back facetradiation captured by the detector is proportional to the amount of radiationemanating from the front facet of the lasing element. This informationenables the system to individually monitor and subsequently control thespot power of the lasing element in a continuous closed loop fashion. |
