Abstract

The invention discloses a wavelength-tunable double-ring structure plasmon laser based on a meta-material antenna. The laser comprises the components of a top patch antenna, a metal transmission wire,a meta-material antenna dielectric layer, a cladding of a laser resonant cavity, a silicon substrate, a semiconductor-insulator-metal stripe-carried sandwich structure based deep sub-wavelength plason waveguide (SIMS waveguide in short) and a metal split ring resonator array. According to the wavelength-tunable double-ring structure plasmon laser, the meta-material antenna is used as a modulatorand realizes high-efficiency modulation to the wavelength of the plasmon laser by means of a microwave in a sub-wavelength scale; and a resonant chamber with a double-ring structure is utilized for realizing tuning of wavelength output from the laser. The laser has advantages of compact structure, simple manufacture process and high controllability of output light. The novel meta-material photoelectric device in which microwave signal absorption and light wave modulation are integrated is constructed. A new technological principle and a new realizing approach are supplied for miniaturization and integration of a high-performance microwave photon device in future.
