Paper Abstract

We use a quasi-three-dimensional numerical model combining finite element calculations in the x - y plane and a longitudinal optical model for the design and the simulation of wide band superluminescent InGaAlAs/InP light emitting diodes (SLEDs). It is shown that by using an active region with a continuously varying composition, bulk devices can provide singlelobe spectra of more than 100 nm full-width-at-half-maximum (FWHM) and output powers of a few tens of mW. This is broader than multiple quantum-well (MQW) device singlelobe spectra which do not exceed ~70 nm FWHM in the same power range.
