Paragraph starter

The integration of photonic integrated circuits (PICs) with electronic integrated circuits (EICs) presents a promising avenue for advancing millimeter-wave beam steering capabilities. As discussed by Cao et al. (2015), PICs offer advantages in terms of ultra-broad bandwidth and low signal loss, which are critical for high-frequency applications. However, the maturity of photonic integration technology is still developing. By employing a hierarchical design where PICs manage large-array delays and EICs handle sub-array delays, designers can leverage the strengths of both technologies to create more robust and efficient beam steering systems for next-generation wireless networks.
