Abstract

We present a multiwavelength fiber source based on cascaded of four-wave mixing in two semiconductor optical amplifiers followed by further four-wave mixing in an optical fiber enhanced by Raman amplification. The multiwavelength source is generated by two initial frequencies detuned 200 GHz and referenced in the absorption lines of the acetylene ¹²C₂H₂, which sweep in frequency keeping the detuning of the lasers constant. With this configuration, we have achieved a high resolution source with a spectrum of 36 channels centered with adjustable peaks separation. The source can be employed to interrogate a fiber Bragg grating sensors network and in gas spectroscopy applications.
