Abstract
Optical wireless links can offer a very large bandwidth and can act as a complementary technology to radiofrequency links. However, optical components nowadays are rather bulky. Therefore, we have investigated the potential of silicon photonics to fabricate integrated components for wireless optical communication. This paper presents a two-dimensional phased array antenna consisting of grating couplers that couple light off-chip. Wavelength steering of 0.24 degrees/nm is presented, reducing the need of active phase modulators. The required steering range is 1.5 degrees. The 3dB angular coverage range of these antennas is 0.007pi sr with a directivity of more than 38dBi and antenna losses smaller than 3dB. Related Research Topics
