Abstract
An optical module includes a photodiode disposed in front of a laser diode with an offset from an optical axis of the laser diode, for monitoring the power of an optical beam emitted from the laser diode in a forward direction. The optical module further achieves switching between a transmission mode and a reception mode in response to a drive current supplied to the laser diode.
