Research output: Contribution to journalConference articlepeer-review


We present the design of optical slot Yagi-Uda antennas and demonstrate the directional radiation from optical slot Yagi-Uda antennas. By calculating the phase between a feed slot and an auxiliary groove, we can find out parameters where the groove works as a good reflector and fabricate optical slot Yagi-Uda antennas with a good directivity. Through coupling with the optimized optical slot Yagi-Uda antenna, random light from quantum dot light emitting diodes can be directed towards a specific direction well.
