摘要：
A collective process is presented to achieve a four-channel fibres ribbon with long working distance micro-optics (46 +/- 0.7 mu m) and UV-induced Bragg gratings. Four different external cavity single-longitudinal-mode sources are obtained with this fibre ribbon in front of a Fabry-Perot laser diode (FP/LD) at a wavelength of around 1300 nm with a side mode supression ratio of 44.35 +/- 1.85 dB, a 3 dB bandwidth of 76 +/- 1.7 pm (13.7 GHz) and a relative intensity noise around -138.6 +/- 2.8 dB/Hz. This is promising for assembling multichannel multiwavelength emitters for dense wavelength division multiplexing (DWDM) networks. (C) 2000 Elsevier Science B.V. All rights reserved.
