Optical module

An optical module, comprising:

• a circuit board;
• and
• a hybrid integrated optical chip, electrically connected to the circuit board and configured to modulate and generate an optical signal, wherein the hybrid integrated optical chip comprises:
• a Si-based platform, comprising a substrate layer, a cladding layer located above the substrate layer, and a Si waveguide layer located between the substrate layer and the cladding layer, wherein a first heating part and a second heating part are embedded in the cladding layer;
• an InP light-emitting region, disposed on the Si-based platform, wherein a plurality of lasers are arranged side by side in the InP light-emitting region;
• the lasers each comprise an active quantum well layer and a grating layer;
• the active quantum well layer is configured to output light;
• and the grating layer is disposed on a surface of the Si waveguide layer and configured to perform wavelength selection on the light output by the active quantum well layer;
• and
• an InP modulation region, disposed on the Si-based platform and located on a light output path of the InP light-emitting region to receive light output by the lasers, wherein a plurality of InP modulators are arranged side by side in the InP modulation region and are linear electro-optic modulators;
• the InP modulators are correspondingly connected to the lasers;
• the InP modulators each comprise a first modulation waveguide and a second modulation waveguide, wherein each of the first modulation waveguide and the second modulation waveguide is optically coupled to each of the lasers to receive the light output by each of the lasers and performs signal modulation to generate an optical signal;
• the first modulation waveguide is disposed adjacent to the first heating part, such that a temperature of the first modulation waveguide is regulated via the first heating part;
• and the second modulation waveguide is disposed adjacent to the second heating part, such that a temperature of the second modulation waveguide is regulated via the second heating part.
