Optical transmitter, active optical cable, and optical transmission method

An optical transmitter, comprising:

• a modulation driver configured to draw in a modulation electric current in accordance with a data signal;
• an auxiliary driver configured to draw in or draw out an auxiliary electric current during a no-signal interval of the data signal;
• and
• a light emitting element in or out which a driving electric current flows, the driving electric current resulting from subtracting the auxiliary electric current from a sum of or a difference between a bias electric current and the modulation electric current,
• the auxiliary electric current being set so that the driving electric current during the no-signal interval is not greater than a threshold electric current of the light emitting element.
