Web7 de out. de 2010 · By creating a cantilevered glass waveguide surrounding an inverse taper and injecting a low-index cladding around the cantilever, we demonstrate coupling loss as low as 0.7 dB/facet to 500 nm 400 nm Si N waveguides, with only 0.2-dB polarization-dependent loss and 0.4-dB wavelength-dependent loss from 1480 to 1580 nm. WebHigh-index contrast dielectric waveguides exhibit strong confinement, making the TE and TM modes very different. As a result, device characteristics, such as propagation constant and coupling strength become strongly polarization dependent.
