Abstract: An example electro-optical modulator includes an electrode conversion portion and an optical modulation portion. The electrode conversion portion includes a first input electrode and a second input electrode, where the first input electrode is configured to receive a first modulation signal, and the second input electrode is configured to receive a second modulation signal. The optical modulation portion includes a first modulation electrode, a second modulation electrode, a third modulation electrode, a first modulation arm, and a second modulation arm. The first modulation arm is between the first modulation electrode and the second modulation electrode, and the second modulation arm is between the first modulation electrode and the third modulation electrode. The first modulation electrode is coupled to the first input electrode, and the second modulation electrode and the third modulation electrode are separately coupled to the second input electrode.

Abstract: An example chip may include a substrate, an insulation layer located on a side of the substrate, and a first waveguide and a second waveguide that are in the insulation layer. The second waveguide is located on a side of the first waveguide away from the substrate. A transmission loss of the second waveguide is smaller than a transmission loss of the first waveguide. A first coupling portion of the first waveguide and a second coupling portion of the second waveguide form a first coupling structure, and the first coupling structure is configured to implement optical coupling between the first waveguide and the second waveguide.

Abstract: A tunable laser is provided, including a first reflector, a second reflector, a phase adjustment area, a gain area, a first detector, a second detector, and a controller. The phase adjustment area is located between the first reflector and the gain area, the gain area is located between the phase adjustment area and the second reflector, a reflectivity of the first reflector is adjustable, and a reflectivity of the second reflector is adjustable. The first detector is configured to convert an optical signal of the first reflector into a first electrical signal. The second detector is configured to convert an optical signal of the second reflector into a second electrical signal. The controller is configured to adjust at least one of the reflectivity of the first reflector or the reflectivity of the second reflector based on the first electrical signal and the second electrical signal.

Abstract: The light emitting assembly includes a substrate (1), a laser light source array, and a lens array. The laser light source array is disposed on the substrate (1), the lens array is disposed on a light emitting side of the laser light source array, one lens (3) in the lens array is disposed opposite to at least one laser light source (2) in the laser light source array, a light emitting surface of the lens (3) is a spherical surface, and at least some laser light sources (2) are eccentrically arranged with corresponding lenses (3). In a manufacturing process, lenses (3) of a same structure and laser light sources (2) of a same structure are used, and eccentric distances between the laser light sources (2) and the lenses (3) are changed, so that light emitting assemblies with different divergence angles can be prepared.
