Abstract: An optical sensor module and a packaging method thereof are disclosed, wherein the optical sensor module comprises a substrate having a light sensing element; and a housing made of a transparent material. The housing is connected to the substrate and covers the light sensing element. The housing has a light-receiving area facing the light sensing element, and the inner surface of the housing toward the substrate is provided with a light-shielding coating in a portion outside of the light-receiving area. In this way, optical components such as the light sensor can be effectively protected, and still retain the effect of avoiding noise light interference with the light sensor module.

Abstract: A system is provided for producing an output photon having a predefined frequency. A pump module produces a plurality of pump fields at a plurality of pump frequencies. A photon pair source module generates frequency-correlated photon pairs. A detector module generates a heralding signal subsequent to detecting a first photon of a photon pair, the heralding signal indicative of a frequency of the second photon of the pair. A non-linear photonic element is arranged to (1) receive the heralded second photon and a complementary selected pump field, and (2) to produce an output photon having the predefined frequency. A pump field selector is configured to (1) receive a heralding signal and (2) select, based on the received heralding signal, a pump field of the plurality of pump fields for provision to the non-linear element. Methods, controllers and computer-readable media are also described herein.

Abstract: An electronic device may have a display with a cover layer. An ambient light sensor may be aligned with an ambient light sensor window formed from an opening in a masking layer on the cover layer in an inactive portion of the display. To help mask the ambient light sensor window from view, the ambient light sensor window may be provided with a black coating that matches the appearance of surrounding masking layer material while allowing light to reach the ambient light sensor. The black coating may be formed from a black physical vapor deposition thin-film inorganic layer with a high index of refraction. An antireflection layer formed from a stack of dielectric layers may be interposed between the black thin-film inorganic layer and the display cover layer.
