We achieve an instantaneous RF bandwidth of 8.08 GHz and 17.55 GHz via thermal tuning. Our approach is a significant step towards monolithically integrated photonic RF receivers with reduced complexity, size, and high performance for broadband analog signal processing and digital-compatible signal detection.
