Abstract
In some implementations, a driver circuit may include a source to provide an electrical input and an array of optical emitters arranged in one or more rows and one or more columns. The array of optical emitters may include an optical emitter associated with a row of the one or more rows and a column of the one or more columns. The driver circuit may include a first switch having an open state and a closed state and a capacitive element connected to the row. The first switch in the closed state may cause charging of the capacitive element. The driver circuit may include a second switch having an open state and a closed state. The second switch in the closed state may select the column, and may cause discharging of the capacitive element through the row and the column to provide an electrical pulse to the optical emitter.
