Abstract
A beam generating device includes a semiconductor substrate, having an optical passband. A first array of vertical-cavity surface-emitting lasers (VCSELs) is formed on a first face of the semiconductor substrate and are configured to emit respective laser beams through the substrate at a wavelength within the passband. A second array of microlenses is formed on a second face of the semiconductor substrate in respective alignment with the VCSELs so as to transmit the laser beams generated by the VCSELs. The VCSELs are configured to be driven to emit the laser beams in predefined groups in order to change a characteristic of the laser beams.
