Design of asymmetrical directional couplers on ridge and strip SOI technology with high-dimensional variation tolerance

García-Rodríguez, David; Corral, Juan L.; Llorente, Roberto (The Optical Society, 2018)

[EN] The supermode analysis of asymmetrical directional couplers (ADC) based on SOI technology for strip and ridge structures at 1550 nm is herein reported, targeting to reduce ADC device fabrication requirements. The ...
Dimensional variation tolerant mode converter/multiplexer fabricated in SOI technology for two-mode transmission at 1550 nm

García-Rodríguez, David; Corral, Juan L.; Griol Barres, Amadeu; Llorente Sáez, Roberto (Optical Society of America, 2017-04-01)

The use of an integrated asymmetrical directional coupler for two-mode transmission at 1550 nm is analyzed. The design is based on silicon-on-insulator (SOI) technology and permits mode conversion and mode multiplexing/d ...
Dual Circularly Polarized Aperture Array Antenna in Gap Waveguide for High-Efficiency Ka-Band Satellite Communications

Ferrando-Rocher, Miguel; Herranz Herruzo, José Ignacio; Valero-Nogueira, Alejandro; Bernardo-Clemente, Bernardo (Institute of Electrical and Electronics Engineers, 2020)

[EN] A novel fully metallic Ka-band dual circularly polarized antenna array is presented in this contribution. It consists of 64 circular apertures (8x8) and it is implemented in gap waveguide technology. The antenna ...
Exciting surface plasmons with transformation media

García Meca, Carlos; Ortuño Molinero, Rubén; Martí Sendra, Javier; Martínez Abietar, Alejandro José (Springer Verlag (Germany), 2012-12)

We present a way of exciting surface plasmon polaritons along non-patterned metallic surfaces by means of a flat squeezing slab designed with transformation optics. The slab changes the dispersion relation of incident ...
