Extremely broadband InGaAsP/InP superluminescentdiodes

Abstract

Record broadband characteristics of superluminescent diodes (SLD) are reported. Using two 87 Å In0.53Ga0.47As quantum wells and three 60 Å In0.67Ga0.33As0.72P0.28 quantum wells, the fabricated SLDs exhibit a very broad emission spectrum. The spectral width is nearly 300 nm, covering the range from 1300 to 1585.5 nm.
