Abstract: Some embodiments of the present disclosure provide an optical sensor. The optical sensor includes a semiconductive substrate. A light sensing region is on the semiconductive substrate. A waveguide region is configured to guide light from a wave insert portion through a waveguide portion and to a sample holding portion. The waveguide portion includes a first dielectric layer including a first refractive index. A second dielectric layer includes a second refractive index. The second refractive index is smaller than the first refractive index. A first interconnect portion is positioned in the waveguide portion, configured to transmit electrical signal from the light sensing region to an external circuit. The sample holding portion is over the light sensing region.

Abstract: An optical sensing module is configured to detect a characteristic of a sample. The optical sensing module includes a light source, a light guide plate, a first cladding layer, a light converging layer, a filter layer, and a plurality of sensors. The light source is configured to provide an exciting beam. Positions of the sensors correspond to positions of the holes. After the exciting beam enters the light guide plate, at least one portion of the exciting beam is transmitted to the sample through a portion of the surface of the light guide plate exposed by the holes, the sample is excited by the exciting beam to emit a signal beam, and the signal beam passes through the light converging layer and the filter layer in an order and travels to the sensors. Another optical sensing module is also provided.
