    Abstract: A light-emitting device includes a semiconductor substrate, a surface-emitting semiconductor light source on the semiconductor substrate, a monolithic first dielectric, and a second dielectric. The monolithic first dielectric is transparent to light emitted by the light source and includes first and second micro-lenses adjacent an aperture of the light source and having axes parallel to and offset from an axis of a beam of light emitted by the light source, and a saddle-shaped lens over the aperture of the light source. The saddle-shaped lens connects the first and second micro-lenses and reshapes the beam of light emitted by the light source to have a high aspect ratio. The second dielectric is transparent to light emitted by the light source and encapsulates a light emission surface of the saddle-shaped lens. The second dielectric has a higher refractive index than the monolithic first dielectric.

    Abstract: An electronic device includes an electromagnetic radiation source having an axis, a set of optics disposed about the axis, a reflector disposed about the axis non-symmetrically, and a controller configured to operate the electromagnetic radiation source while controlling a beam steering orientation (e.g., rotation) of the reflector. The reflector is disposed to reflect electromagnetic radiation emitted by the electromagnetic radiation source. The set of optics is disposed to shape electromagnetic radiation emitted by the electromagnetic radiation source and direct electromagnetic radiation received from the reflector into a panoramic field of view about the axis.

    Abstract: Techniques are disclosed by which electronic devices that include line-of-sight optical communication systems may become optically aware of other electronic devices and perform optical communication handshakes with other devices. An electronic device may use a motion sensor to record its posing when it determines, during the performance of an optical communication handshake, that it is pointed at the electronic device with which it is performing the optical communication handshake (or that the other electronic device is within a field of view of the electronic device). A recorded device posing, in combination with optical communications and motion sensor data, may also be used to map another device's location and enable a user of an electronic device to pan away from and break optical communication with the other device, then easily return to a recorded posing that enables a continuation of optical communications with the other device.

    Abstract: An electronic device may have optical sensors. Control circuitry may use sensor measurements in controlling adjustable components and taking other actions. The optical sensors may be self-mixing sensors such as incoherent self-mixing sensors. One or more sensors may be used in gathering sensor measurements. In configurations in which an electronic device contain multiple self-mixing sensors, multi-wavelength measurements can be gathered using incoherent light sources in the sensors that operate a set of different wavelengths. The light source of each incoherent self-mixing sensor may be a superluminescent light-emitting diode, a resonant cavity light-emitting diode, or other amplified or non-amplified spontaneous emission source. Optical systems such as lenses in a housing for an electronic device may be aligned with the self-mixing sensors. Self-mixing sensors may serve as proximity sensors, sensors for detecting touch input, sensors for measuring spectrums associated with targets of unknown materials, displacement sensors, or other sensors.
