Low-loss high-index-contrast planar waveguides with graded-index cladding layers.
We experimentally demonstrate, for the first time, propagation loss reduction via graded-index (GRIN) cladding layers in high-index-contrast (HIC) glass waveguides. We show that scattering loss arising from sidewall roughness can be significantly reduced without compromising the high-index-contrast condition, by inserting thin GRIN cladding layers with refractive indices intermediate between th...
متن کاملLow loss high index contrast nanoimprinted polysiloxane waveguides.
Nanoimprint lithography is gaining rapid acceptance in fields as diverse as microelectronics and microfluidics due to its simplicity high resolution and low cost. These properties are critically important for the fabrication of photonic devices, where cost is often the major inhibiting deployment factor for high volume applications. We report here on the use of nanoimprint technology to fabrica...
متن کاملLow-loss light coupling with graded-index core polymer optical waveguides via 45-degree mirrors.
We experimentally investigate the optical loss of graded-index (GI) core polymer optical waveguides with a 45-degree mirror on their one end fabricated using the photo-addressing method. In addition, we also theoretically analyze the loss of GI square-core waveguides with mirrors using a ray-trace simulation tool. Then, in the waveguide based optical link including the optical path conversions ...
متن کاملLight Guiding in Low Index Materials using High-Index-Contrast Waveguides
We propose a novel high-index-contrast waveguide structure capable of light strong confinement and guiding in low-refractive-index materials. The principle of operation of this structure relies on the electric field (E-field) discontinuity at the interface between high-indexcontrast materials. We show that by using such a structure the E-field can be strongly confined in a 50-nm-wide low-index ...
متن کاملHigh index contrast polysiloxane waveguides fabricated by dry etching
The authors demonstrate the production of low loss enhanced index contrast waveguides by reactive ion etching of IPGTM polysiloxane thin films. The use of a silica mask and CHF3 /O2 etch gas led to large etch selectivity between the silica and IPGTM of !20 and etch rates of !100 nm /min. This work indicates that compact optical circuits could be successfully fabricated for telecommunication app...
