Abstract: A device includes a first mode converter and a second mode converter that define a region between the first mode converter and the second mode converter. The region can contain a plurality of optical modes including at least three modes. The first mode converter and the second mode converter can generate a near-field via a conversion between the plurality of optical modes. The first mode converter can receive an input wave of a first mode and the second mode converter can generate an output wave of a second mode different from the first mode. The first mode converter and the second mode converter can generate a confined near-field via a conversion between the plurality of optical modes.
