Polarized light is produced using a VCSEL light source, wherein at least some of the polarized light is reflected or scattered by an object. At least some of the reflected or scattered polarized light is received in a sensor that is operable selectively to detect received light having a same polarization as the light produced by the VCSEL light source. In some instances, signals from the sensor are processed to obtain a three-dimensional distance image of the object or are processed using a time-of-flight technique to determine a distance to the object.

Three-dimensional imaging and sensing applications using polarization specific VCSELS

A VCSEL device includes a substrate and a laser cavity that includes a gain section disposed between first and second reflectors. The VCSEL device is operable to emit light through a first end of the VCSEL device. The VCSEL device includes an anode surface mount contact and a cathode surface mount contact, each which is disposed at a second end of the VCSEL device opposite the first end of the VCSEL device.

Vertical cavity surface emitting laser devices

Narrow beam divergence semiconductor sources are operable to generate a beam having a substantially narrow beam divergence, an emission wavelength, and a substantially uniform beam intensity. The presence of an extended length mirror can help suppress one or more longitudinal and/or transverse modes such that the beam divergence and/or the spectral width of emission is substantially reduced.
