An optical module includes a shell, a circuit board, a base, a laser assembly and a silicon optical chip. The laser assembly and the silicon optical chip are located on the base. The laser assembly includes an upper box, conductive substrates, laser chips and a light transmitting member. The upper box and the base are combined to provide a cavity. The cavity has an opening and a slot. The laser chips are located on the conductive substrates which are at least partially located in the cavity. The light transmitting member is disposed between the upper box and the base, and is configured to enclose the opening. Light exit surfaces of the laser chips are parallel to a light incident surface of the light transmitting member, and the light incident surface and a light exit surface of the light transmitting member are not parallel.

An optical module includes a shell, a circuit board, a base, a laser assembly and a silicon optical chip. The circuit board is disposed between an upper shell and a lower shell of the shell. The base is located on the circuit board or in a through hole of the circuit board. The laser assembly and the silicon optical chip are located on the base. An upper box of the laser assembly and the base are combined to provide a cavity. Conductive substrates of the laser assembly are at least partially located in the cavity. Laser chips of the laser assembly are located on the conductive substrates. An opening of the cavity is located in an optical path where light emitted by the laser chips is emitted to the silicon optical chip, and a slot of the cavity allows the conductive substrates or wires to extend out of the cavity.
