Author Affiliations +
It is verified by the source-to-fiber coupling experiment that micro holographic lenses (MHLs) can be used as the outside coupler the light emitted form a laser diode to a fiber. Properly arranging the recording geometry using the equation presented in the paper to fabricate MHLs, the performance of a single MHL can replace a complicated optical coupling system, thus resulting in compact configuration, easy alignment and low cost. Proposals for further increasing the coupling efficiency are provided.
