Abstract
Wide electrical tuning of silicon-on-insulator ring resonators is demonstrated using a top cladding layer of nematic
liquid crystals. A tuning range of 31nm is demonstrated for ring resonators guiding the TM mode, covering nearly
the entire C-band of optical communications. Ring resonators guiding the TE mode can be tuned over 4:5nm. The
combination of a liquid crystal director calculation and a fully anisotropic mode solver confirms the interpretation
of these experimental results. The realization of broad and low-power tuning in silicon-on-insulator opens up new
opportunities in the field of tunable lasers, filters, and detectors. |
