摘要：

A　novel　cascaded　DFB　laser,　which　consists　of　two　serial　gratings　to　provide　selectable　wavelengths,　is　presented　and　analyzed　by　the　transfer　matrix　method.　In　this　method,　efficient　facet　reflectivity　is　derived　from　the　transfer　matrix　built　for　each　serial　section　and　is　then　used　to　simulate　the　performance　of　the　novel　cascaded　DFB　laser　through　self-consistently　solving　the　gain　equation,　the　coupled　wave　equation　and　the　current　continuity　equations.　The　simulations　prove　the　feasibility　of　this　kind　of　wavelength　selectable　laser　and　a　corresponding　designed　device　with　two　selectable　wavelengths　of　1.51　μm　and　1.53　μm　is　realized　by　experiments　on　InP-based　multiple　quantum　well　structure.　©　2010　Chinese　Institute　of　Electronics.
