Title:
MULTI-BEAM SEMICONDUCTOR LASER DRIVE CIRCUIT
Document Type and Number:
Japanese Patent JP3443178
Kind Code:
B2
Abstract:
PURPOSE: To provide a multi-beam semiconductor laser drive circuit wherein crosstalk due to drive is reduced.
CONSTITUTION: The title multi-beam semiconductor laser drive circuit consists of a crosstalk reduction circuit 5 to which an analog driving signal S1in for driving a multi-beam semiconductor laser LD1 and an analog driving signal S2in for driving another multi-beam semiconductor laser LD2 are input; and drive circuits 2, 4 to which output signals S1out, S2out from the crosstalk reduction circuit 5 are input respectively. The semiconductor lasers LD1, LD2 are driven through the drive circuits 2, 4.
