High-power broadband superluminescent diodes (SLDs) have been studied for
spectrum-sliced multiwavelength light sources for use in wavelength division
multiplexing systems. We present the design and fabrication of high-power broadband
GaInAsP/InP strained quantum well SLDs with a tapered active region emitting in a
1.55 µm wavelength band. The fabricated device exhibited the high-power operation
of over 1 W. Also, the spectral width has been increased to over 60 nm by using
chirped multiquantum wells which have different well thicknesses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
