On-chip real-time detection of optical frequency variations with ultrahigh resolution using the sine-cosine encoder approach
Abstract Real-time measurement of optical frequency variations (OFVs) is crucial for various applications including laser frequency control, optical computing, and optical sensing. Traditional devices, though accurate, are often too large, slow, and costly. Here we present a photonic integrated circ...
