Abstract
An optical transmission device includes a light source, a driver, and a light receiving element. In accordance with electronic signals supplied from a signal line, the light source emits forward a signal light and emits back a monitor light for monitoring the signal light. The driver is disposed behind the light source and supplies the electronic signals to the signal line. The driver has a reflection area that reflects the monitor light in a direction different from a direction in which the monitor light, which is emitted back from the light source in accordance with the electronic signal, travels. The light receiving element receives the monitor light that is reflected on the reflection area of the driver.
