Abstract: A camera module is provided. The camera module may be separately used as a camera, or may be applied to a terminal device such as a mobile phone or a tablet computer, or a vehicle-mounted device. The camera module includes an optical lens component, a light filtering layer, an image sensor and a drive module. The optical lens component is configured to receive a light beam from a photographed object, and transmit the light beam to the light filtering layer. The light filtering layer is configured to move a position under the drive of the drive module, and respectively transmit light signals filtered at different positions to the image sensor. The image sensor is configured to receive the light signals at the different positions from the light filtering layer, and determine image information based on the light signals at the different positions.

Abstract: A wavelength tunable laser includes: a heating layer, a dielectric layer, reflectors, a transport layer, a support layer, and a substrate layer. The heating layer is located above the transport layer; the transport layer is located above the support layer, and the transport layer includes an upper cladding layer, a waveguide layer, and a lower cladding layer from top to bottom; the reflector is located in the transport layer; the support layer has a protection structure, where the protection structure forms a hollow structure together with the transport layer and the substrate layer, and the hollow structure has a support structure; and the substrate layer is located below the support layer. The heating layer, the reflector, and a part of the transport layer form a suspended structure to prevent heat dissipation. Thus thermal tuning efficiency can be improved, and power consumption can be lowered.
