Abstract
A laser light source with reduced sensitivity to optical feedback effects comprises an emitter device for emitting laser light. A body of electro-optic material is optically coupled to the emitter device for receiving and propagating light emitted by the emitter device. A time-varying electric field is established in the body of electro-optic material. Consequently, the frequency of the light emitted by the laser diode is shifted when it propagates through the body of electro-optic material.
