PURPOSE: An optical module for a multichannel transmitter is provided to reduce crosstalk and to be integrated into a small size. CONSTITUTION: A plurality of optical source parts (110a-110d) generates light. A plurality of electro absorption modulators (EAMs) (120a-120d) converts the light to an optical signal through a high frequency signal. A plurality of high frequency transmission paths (142a-142d) applies the high frequency signals to the EAMs. A combiner (130) integrates the converted optical signals. The high frequency transmission paths are connected to the EAMs by a TW electrode method. [Reference numerals] (110a) First light source; (110b) Second light source; (110c) Third light source; (110d) Fourth light source; (120a) First EAM; (120b) Second EAM; (120c) Third EAM; (120d) Fourth EAM; (130) Combiner
