Optical module

Abstract

The invention discloses an optical module, which comprises a circuit board and a silicon optical chip electrically connected with the circuit board, and is characterized in that the silicon optical chip receives a plurality of light beams with different wavelengths emitted by a semiconductor gain chip on the circuit board and carries out filtering resonance and electro-optical modulation on the light beams; the silicon optical chip comprises an input / output coupler, an optical waveguide, a plurality of filters, a plurality of heaters, a reflector and a high-speed modulator. The input coupler receives light beams emitted by the semiconductor gain chip. The plurality of filters are used for carrying out wavelength screening on the plurality of received light beams; the reflector is used for partially reflecting and partially transmitting the light beams after wavelength screening; the plurality of heaters are respectively arranged on the optical waveguide and the filter and are used for changing the refractive indexes of the optical waveguide and the filter; the high-speed modulator is used for loading an electric signal to the light beam output by the reflector; and the output coupler is used for coupling the signal light output by the high-speed modulator to the optical fiber. The ultra-wide wavelength tuning range and electro-optical high-speed modulation are realized based on the silicon photon integration platform.
