Abstract:

Two new methods for producing transition waveguide structures for coupling stripe geometry double hetrostructure lasers to single mode fibers were evaluated. The first involved producing an elliptical cross section air core in a glass fiber. This air core was to be rounded by local heating and subsequently filled with a liquid to form a waveguide. Elliptical cores were successfully produced, however, when the rounding operation was attempted the cores collapsed. A second experiment involved flattening a conventional round cross section fiber to achieve an elliptical core cross section. This technique has been used to produce fiber cores that are 19 x 7 micrometers from 12.5 micrometer round core fibers. Author
