Coupled slot waveguide s.a.w. resonators

Electronics Letters, 1977
Grooved-grating, waveguided s.a.w. resonators are coupled by the evanescent fields of single-mode slot waveguides formed by layers of MgO on SiO2 substrates. Except for higher out-of-band levels, the transfer characteristics of these devices compare favourably with alternative monolithically coupled s.a.w.-resonator geometries. A 4-pole response with a

Waveguide grating couplers with bandwidth beyond 200 nm

Nanophotonics
We propose and validate a new approach for wideband waveguide grating couplers (GC). The wideband operation is achieved using a slot waveguide grating structure above the conventional channel waveguide.

Slotted Waveguide Array Synthesis in Gap Waveguide Technology

, 2021
The automotive industry is evolving with the advent and development of autonomous cars. For the operation of these vehicles, sensors are needed, and utilising radar technology is a good solution. Slotted waveguide arrays in gap waveguide technology provide a good solution for the radar antennas; their low losses, high performance while keeping a ...
