Claim 0:
1. A solid state light detection and ranging (LIDAR) transmitter with matrix-addressable laser drive circuit, the LIDAR transmitter comprising:
a) a first electrical bus that provides a first voltage potential to columns of the matrix-addressable laser drive circuit;
b) a second electrical bus that provide a second voltage potential to rows of the matrix-addressable laser drive circuit;
c) a plurality of column switches, each of the plurality of column switches connecting one of the plurality of columns to the first electrical bus;
d) a plurality of row switches, each of the plurality of row switches connecting one of the plurality of rows to the second electrical bus; and
e) a plurality of series connected diodes comprising a laser diode electrically connected in series with a second diode, a respective one of the plurality of series connected diodes being electrically connected between a respective column and a respective row of the matrix-addressable laser drive circuit to form the LIDAR transmitter, wherein at least some of the second diodes increase an overall reverse breakdown voltage of the series connected diodes, thereby reducing optical cross talk when the LIDAR transmitter is energized.
