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.

Optical detector module and a method for operating the same

Systems and methods for optical communication are provided. For instance, a method for optical communication can include receiving, by a first coupling module, a power-on signal from a first electronic device coupled to the first coupling module. The method can also include relaying, by the first coupling module, a first optical signal to a second coupling module coupled to a second electronic device. The method can also include relaying, by the second coupling module, in response to receipt of the first optical signal, a second optical signal to the first coupling module. The method can also include activating, by the first coupling module, in response to receipt of the second optical signal, a data transfer circuit for relaying data via an optical communication interface between the first coupling module and the second coupling module.
