Characteristics Improvement of Surface-Emitting Distributed Feedback Lasers With ITO Claddings

In this study, significant improvements in the characteristics of the InAs quantum-dot surface-emitting distributed feedback lasers using indium tin oxide as a cladding material covered by two types of newly designed metal contacts were achieved. Laser characteristics at room temperature including I-V curves, L-I curves, near-field patterns, and lasing spectra are analyzed and discussed. We adopte...
