Abstract

We propose wireless millimeter-wave (MMW) to lightwave (LW) signal converters using a simple planar antenna on LiNbO₃ optical crystal. The LiNbO₃ crystal is bonded with low-κ dielectric material as the substrate. The simple planar antenna is formed with a rectangular patch antenna with a gap and inserted between the bonded structure. An optical waveguide are fabricated on the LiNbO₃ crystal and located between the gap. The LiNbO₃ crystal has relatively lower dielectric constant compared with a LiTaO₃ crystal. Larger antenna size can be obtained using the LiNbO₃ crystal. Additionally, an electro-optic coefficient of the LiNbO₃ crystal is larger than the LiTaO₃ crystal. Therefore, conversion efficiency enhancement can be achieved using the propose device.
