Photonics Dictionary

A waveguide with a rectangular cross section that is composed entirely of dielectric materials.

A waveguide made up of a dielectric material, such as plastic or mica, in a cylindrical form, through which the waves travel.

The use of an electric field or signal to couple a lightwave from one dielectric waveguide into another dielectric waveguide.

A laser with output over a wide range of wavelengths spanning the far-infrared region of the spectrum (30 to 1000 µm); typically, it consists of a metal or dielectric waveguide one to two...

A thin-film device containing miniature optical components connected via optical waveguides on a transparent dielectric substrate, whose lenses, detectors, filters, couplers and so forth perform...
