Abstract
Buried channel waveguides with strip widths of between 2 and 5 μm have been fabricated in K+–Na+-exchanged BK7 glass. We have investigated the effect of burying using the coupling strength to a bulk overlay. Results indicate a decrease in coupling with burying time. Wavelength notch filters based on the evanescent coupling between such guides and multimoded overlays are reported. Notch widths of between 11 and 34 nm have been observed.
