PROBLEM TO BE SOLVED: To excellently drive each light emitting element of a parallel optical link. SOLUTION: While a laser diode array 41 is driven, a thermistor 121 positioned near the array 41 measures the temperature at its vicinity, and inputs the obtained temperature information A to a temperature control circuit 122. The circuit 122 generates a current control signal B which controls the current generated from an LD driver 42 in accordance with the information A. Upon receiving the signal B, the driver 42 controls the driving current C of the array 41 in accordance with the signal B. |
