Claim 22:
23. A method of generating a light detection and ranging (LIDAR) optical beam, the method comprising:
a) providing a two-dimensional array of laser devices comprising a plurality of series connected diodes comprising a laser diode electrically connected in series with a second diode, and where a respective one of the plurality of series connected diodes is electrically connected between a column and a row of a respective matrix-addressable laser drive circuit;
b) configuring at least some of the second diodes to increase an overall reverse breakdown voltage of the series connected diodes so that optical cross talk in the LIDAR optical beam is reduced;
c) switching a first voltage potential to selected columns of the matrix-addressable laser drive circuit; and
d) switching a second voltage potential to selected rows of the matrix-addressable laser drive circuit, thereby forward biasing selected laser diodes in the two-dimensional array of laser devices causing emission of a LIDAR optical beam with a desired pattern with optical cross talk reduced by the series connected second diode.
