optical harmonic

[′äp·tə·kəl här′män·ik]

(solid-state physics)

Light, generated by passing a laser beam with a power density on the order of 10¹⁰ watts per square centimeter or more through certain transparent materials, which has a frequency which is an integral multiple of that of the incident laser light.

The power penalty is resulting essentially from the walk-off time, due to fiber chromatic dispersion, between the two optical harmonics [30].

A cost-effective method for high-quality 60 GHz optical millimeter wave signal generation based on frequency quadrupling

Two optical sidebands of second-order optical harmonics related to the optical carrier are generated and maximized at the output of the modulator, and the two sidebands have a frequency spacing of four times of the driving RF to the MZMs.

Therefore, the mm-wave at 60 GHz is mainly due to the beating of optical harmonics at [+ or -] 2 [w.sub.RF] so that constructive and destructive interaction hardly occurs so the RFSSR values are not influenced.

Therefore, the mm-wave at 60 GHz is due to the beating of optical harmonics at [+ or -] 2[w.sub.RF] and beating of sixth-order optical harmonics with the optical carrier so that constructive and destructive interaction will occurs, and the desired mm-wave will suffer from the power fading induced by fiber dispersion.
