Electrically pumped gap-plasmon mode semiconductor core lasers

摘要

We will examine progress in electrically pumped Metal-Insulator-Metal (MIM) waveguide laser devices. Such structures allow the concentration of both electrically injected carriers and the optical mode into a gain region of just a couple of tens of nanometers in size in two dimensions. We will show results from such waveguide devices, demonstrating the presence of propagating optical modes in these devices. Another aspect of MIM waveguides is their use in Bragg gratings to form distributed feedback lasers. Results will be shown from such Bragg grating devices and key issues in their design discussed.
