Ridge waveguide polarized don't-care semiconductor optical enlarger of integrated modular spot converter

摘要: The light amplifier includes InP substrate, n type buffer layer, passive waveguide active region, ridge and electrodes in top bottom layers. Characters are that second stage wide is setup between layer region. said lateral taper structure. Ridge together makes beam match to optical fiber at far field. divided into three parts: reduced laterally two stages. Features are: good performance field, very high coupling efficiency or alignment tolerance, applicable network, integration photoelectron integration.
