Abstract
We present an optical phased array (OPA) photonic integrated circuit based on an InP generic platform with on-chip amplification. To the best of our knowledge, it is the OPA with the highest on-chip optical gain reported in literature. The proof-of-principle OPA chip has 8 channels and includes a booster semiconductor optical amplifier (SOA), and in-line SOAs for amplification in all arms. We investigated the optical amplification performance at different current injection levels in an 80nm wavelength range. We measured a maximum on-chip optical gain of 8.6dB at 1530nm for an on-chip input laser power of 5dBm, delivering a total output power of 23mW. The results are promising for OPA-based LiDAR systems where output power is critical to increase the sensing range.
