Abstract
A new approach to fabricate large cross-section edge-coupled waveguides on free-standing thin diamond substrates is reported. Combining inkjet printing of photoresist multilayers with photolithographic patterning, both edge and 'coffee stain' effects were successfully eliminated, allowing the fabrication of well-defined, millimetre-scale uniform photoresist micro-stripes which extend to the very edge of the diamond substrate. Subsequent transfer of these micro-stripe structures into diamond by inductively coupled plasma (ICP) etching allowed long edge-coupled waveguides in diamond to be made. Guided wave propagation in these diamond waveguides was also confirmed. (C) 2011 Elsevier B.V. All rights reserved.
