Reflectance and transmittance can be easily configured by selecting the trench width. At sufficiently high angles of incidence, the devices are lossless, apart from material attenuation and scattering due to surface roughness. We numerically simulate a series of devices within the full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as well as for excitation by focused Gaussian wave bundles. Straightforward cascading of the trenches leads to concepts for 1×M-power dividers and a polarization beam splitter.","lang":"eng"}],"_id":"28196","issue":"12","date_created":"2021-11-30T20:04:57Z","doi":"10.1364/osac.437549","volume":4,"ddc":["530"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"publication":"OSA Continuum","project":[{"name":"TRR 142","_id":"53"},{"_id":"56","name":"TRR 142 - Project Area C"}],"citation":{"chicago":"Hammer, Manfred, Lena Ebers, and Jens Förstner. “Configurable Lossless Broadband Beam Splitters for Semi-Guided Waves in Integrated Silicon Photonics.” <i>OSA Continuum</i> 4, no. 12 (2021): 3081. <a href=\"https://doi.org/10.1364/osac.437549\">https://doi.org/10.1364/osac.437549</a>.","mla":"Hammer, Manfred, et al. “Configurable Lossless Broadband Beam Splitters for Semi-Guided Waves in Integrated Silicon Photonics.” <i>OSA Continuum</i>, vol. 4, no. 12, 2021, p. 3081, doi:<a href=\"https://doi.org/10.1364/osac.437549\">10.1364/osac.437549</a>.","bibtex":"@article{Hammer_Ebers_Förstner_2021, title={Configurable lossless broadband beam splitters for semi-guided waves in integrated silicon photonics}, volume={4}, DOI={<a href=\"https://doi.org/10.1364/osac.437549\">10.1364/osac.437549</a>}, number={12}, journal={OSA Continuum}, author={Hammer, Manfred and Ebers, Lena and Förstner, Jens}, year={2021}, pages={3081} }","apa":"Hammer, M., Ebers, L., &#38; Förstner, J.
