- Impedance matching vertical optical waveguide couplers for dense high index contrast circuitsRong Sun
Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA, USA
Opt Express 16:11682-90. 2008..The coupler furthermore shows excellent broadband coupling efficiencies between 1460 nm and 1570 nm...
- Horizontal single and multiple slot waveguides: optical transmission at lambda = 1550 nmRong Sun
Department of Materials Science and Engineering, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, Massachusetts 02139, USA
Opt Express 15:17967-72. 2007..The waveguide loss is mainly due to a-Si material absorption. The addition of a-Si/SiO(2) interfaces does not introduce significant scattering loss in a horizontal multiple slot waveguide compared to a horizontal single slot waveguide...
