Method for the production of a semiconductor laser having several independent wavelengths |
| abstract |
Method for producing a laser with several wavelengths and laser obtained. A first double heterostructure is produced on a substrate (10) by epitaxy with an active layer having a first composition. This first heterostructure is adapted to the substrate, through a mask provided with strip-shaped openings. A second double heterostructure (B, B '...) is grown in the pickled parts with an active layer having a second composition. A groove (24) is etched between the first (A) and the second (B) heterostructure and then a proton bombardment of the groove (24) is carried out. Application in optical telecommunications. |
