The waveguide assembly comprises an embedded waveguide (204) embedded in a substrate material (224) and a waveguide connector (200) coupled to the embedded waveguide (204).

The receiver comprises an optical waveguide, an electrical waveguide and one or more phototransistor amplifiers opto-electrically connecting the optical waveguide to the electrical waveguide.

The optical waveguide core guides a plurality of wavelengths.

The invention relates to a wave guide adapter arranged between a rectangular wave guide with a single cross-section and an elliptic wave guide which allows for the propagation of a fundamental wave type and higher wave types.

The flexible wave guide mount is secured by the wave guide mount circular clamp, and a flexible wave guide connects to the flexible wave guide mount.

Sidewalls of the waveguide lens connecting the first waveguide to the second waveguide may be curved.

An optical waveguide device contains such an optical waveguide.

The SOA-COS includes a third optical waveguide connected to the first optical waveguide, a fourth optical waveguide connected to the second optical waveguide, and a SOA formed on at least one of the third and fourth optical waveguides.

According to the invention, the optical waveguide is a modified optical waveguide (60) between a ridge-type optical waveguide (61) and a rectangular optical waveguide (62).

The second waveguide may be a waveguide providing an optical gain.

Waveguide paths are formed in the waveguide layer.

The waveguide unit cell can include a first out-of-plane waveguide portion and a second out-of-plane waveguide portion coupled to the first out-of-plane waveguide portion.

The waveguide can be used in an integrated optical waveguide device.

The filter includes an optical waveguide core (106), an optical waveguide cladding (108) and an optical waveguide overcladding (112).

The dielectric waveguide includes a dielectric waveguide core (240) disposed relative to a dielectric waveguide cladding (220) and a common cladding (320).
