When they are matched with the family of ixblue photonics rf drivers, these modulators serve all applications, from laboratory experiments to demanding industrial systems. Mach zehnder interferometers are used in electro optic modulators, electronic devices used in various fiber optic communication applications. Optical modulators are declined under three main families. More specifically, various embodiments of the present invention provide a direct coupled driver device for an optical modulator device, which can be a mach zehnder modulator mzm and the like. In a second type, the mach zehnder modulator mzm, the phase of light in the optical waveguides in an inorganic, semiconductor, or polymer material is modulated, then converted to intensity. Maxlinear launches the mxl9244 45gbaud linear machzehnder. Ingaasp machzehnder interferometer optical modulator. The max3942 is designed to drive highspeed optical modulators at data rates.

Powerful optical modulator driver family for metro. These drivers offer excellent performance in compact surfacemount packages and include features such as gain control and peak detection, as well as the capability to be used in either linear or limiting mode simply by changing the bias conditions and drive level. A phase modulating eom can also be used as an amplitude modulator by using a mach zehnder interferometer. The optical field intensity at the gate is higher for the new device which allows the gate charges to more strongly influence n.
