Cheben, Pavel Fotónica Guías de ondas Waveguides structured at the subwavelength scale frustrate di raction and behave as optical metamaterials with controllable refractive index. These structures have found widespread applications in silicon photonics, ranging from sub-decibel e ciency bre-chip couplers to spectrometers and polarization rotators. Here, we briefly describe the design foundations for sub-wavelength waveguide devices, both in terms of analytic e ective medium approximations, as well as through rigorous Floch-Bloquet mode simulation. We then focus on two novel structures that exemplify the use of subwavelength waveguides: mid-infrared waveguides and ultra-broadband beamsplitters. 2017-02-06T07:55:12Z 2017-02-06T07:55:12Z 2017-01 2017-02-06 conference output http://hdl.handle.net/10630/12905 http://orcid.org/0000-0002-5560-3189 eng Photonics West San Francisco Febrero 2017 open access by-nc-nd
