Abstract
An optical system and a method of manufacturing an optical system are provided. The optical system includes a carrier, a light emitter, a light receiver, a block structure and an encapsulant. The light emitter is disposed on the carrier. The light receiver is disposed on the carrier and physically spaced apart from the light emitter. The light receiver has a light detecting area. The block structure is disposed on the carrier. The encapsulant is disposed on the carrier and covers the light emitter, the light receiver and the block structure. The encapsulant has a recess over the block structure.
Claims20
An optical system, comprising:
- a light emitter disposed on a carrier;
- a light receiver disposed on the carrier;
- a block structure configured to mitigate a crosstalk between the light emitter and the light receiver;
- and
- an encapsulant encapsulating the light emitter and the light receiver,
- wherein a portion of the block structure is exposed from the encapsulant and below the encapsulant.
An optical system, comprising:
- a light emitter disposed on a carrier;
- a light receiver disposed on the carrier;
- and
- a block structure configured to mitigate a crosstalk between the light emitter and the light receiver, wherein the block structure has a recess recessed from a top surface of the block structure and spaced apart from the carrier.
An optical system, comprising:
- a light emitter disposed on a carrier;
- a light receiver disposed on the carrier;
- a block structure disposed between the light emitter and the light receiver;
- and
- an encapsulating structure encapsulating the light emitter and the light receiver,
- wherein the encapsulating structure defines a first opening within the encapsulating structure, and the block structure defines a second opening within the block structure and connected to the first opening.
