Abstract
Optical functions such as Q-switching, mode locking, cavity dumping, and modulation are generated by a simple laser arrangement which includes a gain medium and an electrically controllable, optical waveguide device optically coupled to the gain medium. The gain medium and waveguide device are either interposed between two reflective surfaces or coupled by a waveguide in order to form a single composite cavity laser structure.
Claims6
An optoelectronic device for generating optical signals including an electrooptic waveguide means being electrically controllable for varying a predetermined characteristic therein and including at least one optical waveguide, a gain medium being optically coupled to a first end surface of the at least one optical waveguide, means being optically coupled to both the gain medium and a second end surface opposite said first end surface of the at least one optical waveguide for transferring optical signals between the electrooptic waveguide means and the gain medium such that a single resonant optical cavity is formed in the optoelectronic device.
