Towards low-noise tunable THz generation
Towards low-noise tunable THz generation
We phase locked a commercial telecom ITLA (integrable-tunable-laser-assembly) laser to an optical frequency comb with carrier frequency within the telecom C- band (1527 nm - 1565 nm). We achieved short-term integrated phase noise of 1.1 rad2 and long-term frequency stability below ± 0.4 Hz. Fractional frequency instability for Terahertz source generated via photomixing of two such lasers is calculated and compared with the state-of-the-art.

Abstract
We phase locked a commercial telecom ITLA (integrable-tunable-laser-assembly) laser to an optical frequency comb with carrier frequency within the telecom C- band (1527 nm - 1565 nm). We achieved short-term integrated phase noise of 1.1 rad2 and long-term frequency stability below ± 0.4 Hz. Fractional frequency instability for Terahertz source generated via photomixing of two such lasers is calculated and compared with the state-of-the-art.
