In general, an electro-optic EO modulator transforms an electrical signal into an optical signal. The incoming electrical signal is most commonly information encoded in a voltage change. This voltage change mach-zehnder optical modulator then transformed into either a phase change or an intensity change in the light signal.

Optimizing Mach-Zehnder Modulator Designs with COMSOL Software COMSOL Blog

The mach-zehnder optical modulator voltage needed to drive the modulator and the lower the optical loss, the higher the link gain and, therefore, the better the performance of the modulator. In this review, we will show how sol-gels can be used to enhance the performance of electro-optic modulators by allowing for designs with low optical loss, increased poling efficiency and manipulation of the electric field used for driving the modulator.

Mach-zehnder optical modulator optical loss is influenced by the propagation loss in the device, as well as the losses occurring during fiber coupling in and out of the device. In both cases, the use of sol-gel materials can be beneficial due to the wide range of available refractive indices and low optical attenuation.

The influence of material properties and synthesis conditions on the device performance will be discussed. An electro-optic modulator -assisted wavevector-resolving Brillouin light scattering setup.

mach-zehnder optical modulator Brillouin light scattering spectroscopy is a powerful technique which incorporates several extensions such as space- time- phase- and wavevector-resolution. Here, we report on the improvement of the wavevector-resolving setup by including an electro-optic modulator. This provides a reference to calibrate the position of the diaphragm hole which is used for wavevector selection.

The mach-zehnder optical modulator of this calibration is only limited by the accuracy of the wavevector measurement itself. To demonstrate the validity of the approach the wavevectors of dipole-dominated spin waves excited by a microstrip antenna were measured.

Microring resonator based modulator made by direct photodefinition of an electro-optic polymer. Balakrishnan, M.


A laterally mach-zehnder optical modulator microring resonator was fabricated by direct photodefinition of negative photoresist SU8, containing tricyanovinylidenediphenylaminobenzene chromophore, by exploiting the low ultraviolet absorption window of this chromophore. The ring resonator was first photodefined by slight cross-linking. Thereafter, poling to align the chromophores and further cross-linking to increase the glass transition temperature were simultaneously carried out. Multiple p-n junction subwavelength gratings for transmission-mode electro-optic modulators. We propose a free-space electro-optic transmission modulator based on multiple p-n-junction semiconductor subwavelength gratings.

Exceptionally large electro-optic coefficient and high-speed modulation at nm in DAST single-crystal film has been recently reported. The single-crystal film was prepared by the modified shear method. The modulation measurement was performed in the transverse configuration using the field-induced birefringence method. A semiconductor laser was used for this experiment. The light beam was propagated perpendicular to the film and the modulation was recorded for an ac field applied along the dipole axis mach-zehnder optical modulator the film. About 6. Thakur, A.
