Abstract
The present invention is an improved method of pigtailing of high-density Wavelength Division Multiplex (WDM) components, achieved by etching silicon V-grooves for locating the fibres after completion of the PLC device fabrication processes. This avoids the need for etching or pre-patterning of the V-grooves on substrates before device fabrication, and hence avoids any of the waveguide to fibre alignment problems that have been found in the methods of the prior art.
