HeαNe laser lightwaΒ¨es in an optical fiber are directly modulated by applying audio frequency modulating electric fields at the input end. Temporal drift of the output signal and its dependency on detector location are presented.

HeαNe laser lightwaΒ¨es in an optical fiber are modulated when a short section of the fiber is subjected directly to audio frequency electric fields. The laser light emerging from the fiber output endface is intensity modulated, phase shifted, or modulation frequency multiplied under special conditio
## Abstract Wavelengthβdivision multiplexed optical systems require an accurate knowledge of the crossβphase modulation due to the Kerr effect, which generates a nonlinear phase modulation of each channel depending on the overall power in all of the other channels. In this letter, the spectral char
