An illustrative proximity sensor is disclosed to include a light source, a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal, and a plurality of polarization layers stacked on the photodetector that limit light from becoming received incident light for the photo-sensitive area to light traveling toward the photodetector along a predetermined path.

Abstract: Disclosed are various embodiments of an infrared proximity sensor package comprising an infrared transmitter die, an infrared receiver die, a housing comprising sidewalls, a first recess, a second recess, a partitioning divider disposed between the first and second recesses, and an overlying shield comprising an infrared-absorbing material. The transmitter die is positioned in the first recess, and the receiver die is positioned within the second recess. The partitioning divider comprises liquid crystal polymer (LCP) such that the partitioning divider and the infrared-absorbing material of the shield cooperate together to substantially attenuate and absorb undesired infrared light that might otherwise become internally-reflected within the housing or incident upon the receiver as a false proximity or object detection signal.

The optical structure may provide an optical path to allow radiation reflected by a near object that may be otherwise blocked by the body to be transmitted towards the receiver die. In addition to the proximity-sensing device, a sensing device having at least two trenches that allow close proximity sensing is disclosed. A method for sensing an object that involve determining whether the object correspond to a near object or a far object is presented.

Abstract: An optical sensor for detecting at least one of proximity and gesture is disclosed. The optical sensor is configured to detect or sense an object that is located out of the sensor's primary axis. This off-axis detection is facilitated by projecting light emitted by a light source away from the sensor's primary axis and away from the direction in which the light was originally emitted by the light source. The light detector is also configured to detect the light that is being projected off-axis.
