Abstract:
A receiving-side splitter  4  that constitutes part of an optical communication device  1  splits a receiving-side signal light into a plurality of lights at a splitting ratio according to the intensity distribution of mutually different propagation modes included in the receiving-side signal light passed through a transmission medium  3.  A transmission-side splitter  10  splits a transmission-side signal light into a plurality of-lights. A signal processing device  5  detects the light intensity and/or the phase of the receiving-side signal light, and sets a control target value for the light intensity and/or the phase of the transmission-side signal light to a value according to the result of the detection. A modulator  9  adjusts the light intensity or the phase of a the transmission-side signal light so that the light intensity or phase equals the set value. A multiplexer  8  multiplexes the plurality of transmission-side signal lights.

Claim (Index 8):
An optical communication method comprising:\n receiving a reception-side signal light incident through a free space by using a transmission medium of a multimode type; distributing the reception-side signal light into a plurality of distributed reception-side signal lights at a distribution ratio, the distribution ratio being ratio depending on an intensity distribution of a plurality of mutually different propagation modes included in the reception-side signal light after passing through the transmission medium; detecting either or both of a light intensity and a phase in each distributed reception-side signal light; distributing a transmission-side signal light to be transmitted to a plurality of distributed transmission-side signal lights; setting a control target value for either or both of a light intensity and a phase to be controlled in each distributed transmission-side signal light to a value depending on a result of the detecting; adjusting either or both of a light intensity and a phase to be controlled in the distributed transmission-side signal light to the control target value after setting; and multiplexing a plurality of distributed transmission-side signal lights obtained after being adjusted and emitting a multiplexed transmission-side signal light.
