In this paper, a novel silicon-on-chip integrated 4 × 1 wavelength division multiplexing (WDM) multiplexer has been developed. This is the first time that the multiplexer design incorporates arrayed ...

The light input to a semiconductor optical modulator can constitute an electrical energy supply through the photovoltaic effect, which is unexploited in conventional modulators. In this work, we ...

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has successfully developed a highly efficient optical modulator using the organic ...

Microelectromechanical system (MEMS) optical modulators are crucial in next-generation technologies such as free-space optical communication and LiDAR, but existing designs struggle with balancing ...

The National Institute of Information and Communications Technology has successfully developed a highly efficient optical modulator using organic electro-optic polymer (hereinafter referred to as EO ...

Success in the development of a “polymer optical modulator,” which has been said to be difficult to put into practical application With the recent dramatic increase in information communication ...

The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high speed control of optical field coherence.

Researchers from ETH Zurich and its spin-out company Polaritron have created a moduator for infra-red that works up to 1.1THz. It is a modulator with two gold electrodes on a substrate facing each ...
