Abstract
A device may include an input optical path, a first optical path, a plurality of second optical paths, a first optical amplifier, a plurality of second optical amplifiers, and a control circuit. The input optical path may receive, at one end thereof, a beam from a laser source. The first optical path and the second optical paths may be respectively branched from at the other end of the input optical path. The first optical amplifier may be coupled to the first optical path. The second optical amplifiers may be respectively coupled to the second optical paths. The control circuit may selectively turn on one of the second optical amplifiers to output a modulated optical signal of the beam. The control circuit may turn on the first optical amplifier, in synchronization with turning on any one of the second optical amplifiers, to output a local oscillator (LO) signal.
