WebFeb 10, 2024 · Wiring up transistors of an optical circuit with silicon waveguides is crucial for compact, highly integrated chips. And it’s easier to integrate other components such as electrodes if the waveguide is made of silicon — a cheap and abundant material that happens to be an excellent semiconductor. WebOptical waveguides exploit the electrical vector of totally internally reflected light. The electrical vector of this light extends for a fraction of a wavelength beyond the immediate physical boundary of the waveguide, and in this way the waveguide is sensitive to sample environmental changes that take place on the surface. Notably, these are ...
