Abstract: An adjustable hyperspectral detection chip enhanced by a multi-resonance plasmonic mechanism. The detection chip consists of an array of metal nanonail resonator detection units. Each detection unit (1) comprises: a bottom electrode (2), a semiconductor material layer (3), a spacer layer (4), a nanonail array (5), a control material layer (6), a top electrode (7), a peripheral control signal (8), and a driving circuit (9). The positional relationship from top to bottom is the top electrode (7), the control material layer (6), the nanonail array (5), the spacer layer (4), the semiconductor material layer (3), and the bottom electrode (2). The nanonail array (5) is loaded inside the control material layer (6), and the peripheral control signal (8) and the driving circuit (9) are connected to both sides of the control material layer (6).

Abstract: A surface plasmon infrared nano-pulse laser having a multi-resonance competition mechanism, consisting of the four parts of a surface plasmon nano-pin resonance chamber (1), a spacer layer (2), a gain medium (3), and a two-dimensional material layer (4). The surface plasmon nano-pin resonance chamber (1) consists of a metal nano rod (11) and one or more nano sheets (12) grown thereon, the surface plasmon nano-pin resonance chamber (1) and the gain medium (3) being isolated by the isolating layer (2), and the two-dimensional material layer (4) covering a surface of the surface plasmon nano-pulse laser; positive and negative electrodes (5) are located at two ends of the surface plasmon nano-pulse laser, and a layer of a two-dimensional material having a feature of saturatable absorption is introduced to a surface of the nano-pin resonance chamber.
