Beschreibung
Zusammenfassung:	A semiconductor optical modulator in which a radio frequency (RF) line which is disposed parallel to an optical waveguide and has a differential line for transmitting an RF modulation signal, a connecting pad which is formed in the same direction continuously with the RF line, and a termination resistor which has two rectangular resistors for differentially terminating the RF modulation signal from the connecting pad are linearly disposed, and terminated on-chip, and the RF line which forms a differential pair immediately after passing through the termination resistor is short-circuited.
