Sensors with a fixed wavelength source can only detect SPP waves over a limited range of refractive index of the partnering dielectric material, but this limited range can be shifted by the application of a

Generally tilted in-core fiber gratings are modeled by an equivalent inhomogeneous optical thin film. Its reflectance spectrum is evaluated using the
Automated equipment for measuring and connecting optical fibers to chips and panels is therefore essential. At Fraunhofer IZM we have an EFRE-funded facility

The realization of this directional coupler necessitated the development of an integrated quasi-optical substrateless silicon platform that is
A grating coupler is defined as a device that uses a periodic structure to diffract light in and out of an optical fiber by directing vertically incident light into waveguides through the principle of diffraction. Its
A variety of thin films suitable for optical wave guiding has been reported so far. These films include epitaxial layers of high resistivity on low resistivity GaAs (Ref. 10), composite structure of GaAs
Multilayer Dielectric Thin-Film Filters (TFF) DTMFs can be designed to have flat passbands, low lows, low PDL and polarization sensitivity as well as sharp frequency rolloff.
Coupling Between Waveguides The phenomenon of optical tunneling can be used not only to couple energy from a fiber or a beam to a waveguide, as described in Chapter 7, but also to couple one

One method to make waveguide or fiber couplers is to use straight sections of the guides where the evanescent modes of one guide overlap with the modes of a
Fiber couplers, circulators, and free-space beam splitters are used to build a system interferometer. To achieve the maximum ranging depth possible, it is desirable to use the full coherence length of the
Unlike tra-ditional directional couplers, the demonstrated subwavelength directional fiber coupler shows less dependency on the overlapped length of two fibers and the delivered THz
