摘要:
An InGaAs/InGaAsP multiquantum well superluminescent diode (SLD) emitting at 1.5-mu-m has been studied. Broad spectral widths exceeding 100 nm are achieved under a wide injection current range. The maximum spectral width is 170 nm, which gives a calculated coherence length of 13-mu-m, approximately one third that of 1.5-mu-m conventionally available bulk SLDs.
