Dynamic Device Characteristics and Linewidth Measurement of InGaN/GaN Laser Diodes
This paper uses a parameter extraction method to investigate key parameters in GaN-based DFBs, as well as spectral linewidth measurements. Single-wavelength blue laser diodes are becoming a topic of significant research interest and gaining a better understanding of the device performance will allow improvements in design and ultimately improve their use in a number of commercial applications. To the authors’ knowledge this is the first reporting of these parameters in GaN devices.
