Abstract:
A solid state LIDAR transmitter with matrix-addressable laser drive circuit includes a first electrical bus that provides a first voltage potential to columns of the matrix-addressable laser drive circuit and a second electrical bus that provide a second voltage potential to rows of the matrix-addressable laser drive circuit. A plurality of column switches connects the plurality of columns to the first electrical bus. A plurality of row switches connects the plurality of rows to the second electrical bus. The transmitter includes a plurality of series connected diodes comprising a laser diode in series with another diode, where a respective one of the plurality of series connected diodes is electrically connected between a respective column and row of the matrix-addressable laser drive circuit to form the LIDAR transmitter. At least some of the second diodes increasing an overall reverse breakdown voltage of the series connected diodes.
