A solid-state device, and use and formation thereof. The device includes a light emitter (102) that emits light with abeam propagation direction and includes an emitter epitaxial layer stack (940); a light routing medium (103) in optical communication with the light emitter; and a light detector (104) in optical communication with the light routing medium, which detects light emitted by the light emitter and includes a detector epitaxial stack (945).

One or more systems and/or methods are disclosed for building a relief print generator with no bezel. An electrode layer having more than one electrode can be used in an electrode-based, electro-luminescence component of the relief print generator. The respective electrodes may be connected to power sources with different voltage phases. An electrical circuit can be created between a biometric object and more than one electrode in the electrode layer when the biometric object contacts a surface of the generator. The electro-luminescent component can be activated by electrical charge and emit light indicative of a relief print of the biometric object. A contact electrode outside the electrode layer may not be used, which may allow for the removal of a bezel from an example device.

A sensing system comprising an emitter configured to emit electromagnetic radiation, a detector configured to detect electromagnetic radiation and an electronic component configured to interact with a circuitry of the sensing system. The electronic component is located at least partially between the emitter and the detector. The electronic component reduces an amount of electromagnetic radiation propagating from the emitter to the detector. The electronic component advantageously reduces the unwanted detection of electromagnetic radiation that would otherwise propagate directly from the emitter to the detector without leaving the sensing system, thereby reducing a measurement noise and improving an accuracy of the sensing system. The sensing system may form part of a time-of-flight sensing system or a proximity sensing system. The sensing system may form part of an electronic device such as a mobile phone.
