Abstract:

Experimental data and modeling are presented which show that under appropriate conditions a set of index-guided modes can exist and have lower thresholds than gain-guided supermodes for twin-stripe semiconductor lasers. It is also shown that more than the two modes predicted by supermode theory can simultaneously lase. The near-field and far-field profiles of the index-guided modes will be shown to have a narrower extent than those predicted by supermode theory and, in the case of the fundamental mode, be single-lobed. Keywords Laser diode Supermode Higher order mode Spectrally resolved near field Gain guided Index guided Twin stripe Two stripe Array Near field Far field.
