概要

• 論文の詳細を見る

• A GaAs/AlGaAs directional-coupler-type device that use polariton propagation was fabricated and its switching operation was demonstrated. The length of the switching region is as small as 300μm. The output signal modulation under an electric field shows typical characteristics of directional-coupler type switching. The measured operation voltage is 2 V for an operation wavelength of 805 nm at 10 K. The corresponding signal extinction ratio is 8dB. These experimental results confirm the efficient operation of the polariton devices, which can be applied to especially small optical-switching devices with low-voltage operation.
