摘要（英）：

The invention discloses a system and a method for generating a small-mode laser beam on a chip based on silicon-based mode conversion. The invention belongs to the field of integrated optics. The system comprises a silicon-based waveguide (1) and an optical fiber system (2), wherein, the silicon-based waveguide (1) comprises a silicon-based waveguide coupler (14, 15), a few-mode silicon-based modemultiplexer (16)/demultiplexer (13), a few-mode silicon-based waveguide (12), and a few-mode silicon-based power coupler (14); The optical fiber system (2) includes a pump source (24), an optical isolator (23), an erbium-doped optical fiber (26), a single-mode optical fiber (22), an optical wavelength division multiplexer (25), an optical channel selector (27), and an optical coupler (21). The system uses semiconductor laser as pump source, erbium-doped fiber as gain medium, fiber system and silicon-based waveguide to construct ring resonator, and generates few-mode laser by controlling silicon-based mode conversion, which provides an effective technical scheme for the construction of high-density system on chip.
