Abstract

The invention provides a nano-plasma array laser and a manufacturing method thereof, belonging to the field of optical technology. The invention utilizes the interaction between the photons excited by the p-n junction array of electrically pumped semiconductor nanowires and the surface metal-dielectric film to generate surface plasmon polaritons (SPPs), and then constrains and regulates the photon beams generated in the nanowire resonant cavity . The present invention combines the dual advantages of geometric limitation of semiconductor nanostructures and surface plasmon mode field constraints on light beams, uses semiconductor nanowires to realize the integration of working materials and resonant cavities and surface plasmons to achieve mode field constraints, and finally forms a semiconductor nanoplasma laser .

Description

technical field

[0001] The invention belongs to the field of optical technology, and in particular relates to a nano-plasma array laser and a manufacturing method thereof. Background technique

[0002] Since the first laser was produced 50 years ago, some new nanotechnology has improved the micro-laser to a new field, which has set off a research boom of nano-laser. At present, the widely used nanolasers mainly include optically pumped nanoplasmonic lasers and electrically pumped semiconductor nanowire array lasers.

[0003] Optically pumped nanoplasmonic laser consists of a single semiconductor cadmium sulfide (CdS) nanowire placed horizontally on a metal-dielectric composite film to form a nanoplasmonic laser, and laser emission is achieved through pulsed laser pumping; The nano-scale slit realizes the surface plasmon local field enhancement effect for plasmon-optical hybrid pumping, and realizes laser emission at the end of the nanowire. The excitation light mode is rest...
