Broad Bandwidth Emission From Hybrid QW/QD Structures

Not Accessible

Your library or personal account may give you access

Abstract

We previously demonstrated a hybrid quantum well/quantum dot structure to enhance the gain and spontaneous emission bandwidth of a quantum dot active region. We now present new designs to further broaden the spontaneous emission from hybrid QW/QD structure. Utilizing a high junction temperature, and chirped quantum dot layers with higher areal densities, increased layer number, and increased state separation a spontaneous emission FWHM of ~350nm is achieved.
