An improved highly doped waveguide is provided which comprises a waveguide employing an Er dopant and Pr sensitizer ions. The present invention also provides a method of efficient coupling from an optical source into a waveguide using a rotated optical element.

Method for efficient coupling of laser beams into waveguides

The present invention relates generally to electro-optically active waveguide segments, and more particularly to the use of a selective voltage input to control the phase, frequency and/or amplitude of a propagating wave in the waveguide. Particular device structures and methods of manufacturing are described herein.

Tunable bragg grating and devices employing the same

An improved highly doped waveguide is provided which comprises a waveguide having a dopant disposed therein, the dopant having a concentration of between 100 and 500,000 ppm, and wherein the concentration of the dopant enhances cross-relaxation between two elements of the dopant.

Highly doped fiber lasers and amplifiers

An improved method and apparatus for mode-locking a fiber laser at a pre-selected frequency wherein a doped fiber segment contains a narrowband FBG and an electro-optically tuned FBG, thereby making obsolete the need for an EOM to modulate the laser's wavelength. The present invention also provides a method and apparatus for mode-locking a fiber laser at a variable frequencies wherein a doped fiber segment contains two electro-optically tuned FBG's. The electro-optically tuned FBG may be fabricated by a thermal poling process.
