CHILDS, D. et al. Flat-topped emission centred at 1 250 nm from quantum dot superluminescent diodes. S. Afr. j. sci. [online]. 2009, vol.105, n.7-8, pp. 276-277. ISSN 1996-7489.

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 at 1 250 nm, and with output power in excess of 8 mW.

Palabras clave : quantum dot; superluminescent diode; broadband.
