Internally it is a resonant electro optic modulator with the capability of generating hundreds of sidebands with total span of at least 3 terahertz limited by the optical dispersion of the lithium niobate crystal and frequency spacing of 17 ghz.

Terahertz frequency comb generator.

Terahertz frequencies have long promised to transform communications and sensing but are very challenging to source. An optical comb generator can be used as generators of terahertz radiation. A femtosecond mode locked fs ml laser generates a sequence of pulses that are essentially copies of the same pulse separated by an interval equal to the inverse of the mode locked frequency f rep yasui et al 2011a the highly stable fs ml pulse train is synthesized by a series of. Figure 15 1 illustrates the principles of an optical comb and a thz comb in the time and frequency domains.

By harnessing a recently discovered laser state seas researchers have discovered an infrared frequency comb in a quantum cascade laser that offers a new way to generate terahertz frequencies. Frequency combs based on terahertz quantum cascade lasers which combine the high power of lasers with the broadband capabilities of pulsed sources are demonstrated. The frequency combs generate. In this work we report exact tunable frequency synthesis and phase control of a terahertz laser.

Ye j ma ls daly t hall jl. We clearly observed beat signals between the terahertz source and the optical two tone extracted. Using a 10 5 ghz resonant electro optic modulator placed inside a resonant optical cavity we generated an optical frequency comb with a span wider than 3 thz. Highly selective terahertz optical frequency comb generator.

Researchers at the universidad carlos iii of madrid uc3m and the firm luz wavelabs are developing an innovative terahertz generator that improves signal quality by one million times as compared. Bridge wide frequency intervals usually more than a few terahertz phase coherently. Terahertz optical comb generator researchers at jila university of colorado national institute of standards and technology and new focus have used a prototype model 4851 that resonated at 10 5 ghz to generate a spectrum of sidebands over 3 thz wide around a stabilized 633 nm hene laser source that s over 250 sidebands at 10 5 ghz.
