Optoelectronics: Continuously Spatial-Wavelength-Tunable Nanowire Lasers on a Single Chip
Abstract
Extensive research has been conducted in growing and characterizing semiconductor nanowires, especially in demonstrating unique lasing capabilities of our nanowire materials and structures. The key results achieved include a novel growth method strategy that is termed dualgradient method . This dual gradient method has been utilized to grow a wide range of novel alloy semiconductor nanowires and led to a wide array of new nanomaterials such as first quaternary semiconductor alloy nanowires, spatial-composition graded alloy nanowires with emission covering the complete visible spectrum emission from a single substrate, and widely tunable lasing on a single substrate from 500 to 700 nm. More recently the further exploration of such growth has led to the first dual-color (red and green) lasing from a single nanosheet and dynamically tunable color lasing between green and red from a single nanowire. The second part of the work for the extension period involved investigation of electrical injection single nanowire laser work. Extensive design and fabrication study has been conducted. While our designs have shown great promise and various fabrication steps have been verified, a working electrical injection laser has not been achieved. We believe that we have gained a lot of understanding of the issues involved.
