Abstract
A VCSEL can include: an electro-optic modulator between a lasing active region and a light emitting surface. The electro-optic modulator can include: an electro-optically active region; a modulator mirror region over the electro-optically active region; and at least one electrical insulator region separating the modulator mirror region into at least two separate modulator mirror cavities electrically isolated from each other, wherein each separate modulator mirror cavity and a longitudinally aligned portion of the electro-optically active region form an electro-optic modulator cavity. A method of emitting light from a VCSEL can include: emitting a laser beam from the lasing active region along a longitudinal axis; and changing a refractive index of one electro-optic modulator cavity so as to steer the laser beam from the longitudinal axis.
