Flat-topped emission centred at 1 250 nm from quantum dot superluminescent diodes
We present a method for tailoring a broadband and flat-topped emission spectrum in quantum dot superluminescent diodes based upon modification of the dots-in-compositionally-modulated-well (DCMWELL) technique. We demonstrate flat-topped emission with 95 nm full width at half maximum (FWHM), centred...
