    Abstract: A method includes fabricating a device including a first dielectric layer, an optical waveguide in the first dielectric layer, and a superconducting circuit in the first dielectric layer and on the optical waveguide. The method also includes forming a sacrificial structure on the first dielectric layer, the sacrificial structure aligned with the superconducting circuit, depositing a second dielectric layer on the sacrificial structure, and cutting an opening in the second dielectric layer to expose the sacrificial structure. The method further includes wet etching the sacrificial structure through the opening and sealing the opening in the second dielectric layer with a third dielectric layer to form a micro-channel between the first dielectric layer and the second dielectric layer.

    Abstract: An optical detector module can be used to implement proximity sensing function by detecting ambient light outside of the optical detector module in accordance with a first detection threshold. An optical detector module can be further used to implement other active functions such as material detection (e.g., skin) or depth-sensing by emitting one or more optical signals (e.g., light pulses at a specific wavelength) and detecting the reflected optical signals relative to a second and/or third detection threshold. The disclosure provides technical solutions for actively monitoring detection threshold(s) of an optical detector module to achieve better power management. In some embodiments, such solutions are useful for photodetectors having a wide sensing bandwidth, such as a photodetector formed in germanium or a photodetector comprising an absorption region comprising germanium.

    Abstract: An optical lens has a light sensing die integrated into the optical lens. The optical lens is extended compared to a spherical optical lens such that the optical lens is elongated in order to allow for placement of the ambient light sensing die without causing any blocking or distortion of the optical lens. The shape of the optical lens and the placement of the ambient light sensing die is compensated for the change in shape compared to a spherical optical lens thus allowing for correct focal length parametrics.

    Abstract: An image-capturing and light-sensing optical apparatus has both of an image capturing function and a light sensing function. The image-capturing and light-sensing optical apparatus includes a first optical lens module, a second optical lens module and a casing. The casing has a first opening. The first optical lens module includes a first optical lens and a first optical sensor. According to the working distance or the equivalent focal length of the first optical lens module, the size of the first optical lens and the size of the first optical sensor, the maximum field of view is acquired. Consequently, the size of the first opening is determined, and the casing is slim. Under this circumstance, the image-capturing and light-sensing optical apparatus complies with the purpose of miniaturization.
