Abstract

The terahertz band (0.3 to 3.0THz) has been found to be spectroscopically rich with many substances possessing strong and unique absorption signatures useful for chemical and biomedical sensing applications [1-4]. Photonics-based methods for spectrum analysis of the incident signal require complex time-domain spectroscopy systems achieving bandwidths more than 1THz but with resolution in GHz range. Classical solid-state down-conversion architectures can achieve much higher resolution but require a large bank of frequency synthesizers and multipliers to generate LO frequencies covering the entire band [1,2]. Evidently, enabling frequency generation on-chip covering the large frequency band (40 to 330GHz in this case) operating above fmax of the solid-state technology is impractical [3,4].
