Erdamar, A.K. (author), Van Leest, M.M. (author), Picken, S.J. (author), Caro, J. (author)We use an elastomer as infill material for a photonic crystal. As a result of the thermal-expansion-induced strongly negative thermal optical coefficient, this material is highly suitable for thermal tuning of the transmission of a cavity. This is demonstrated by global infilling of a hole-type silicon photonic crystal slab and global thermal...journal article 2011

Erdamar, A.K. (author), Van Leest, M.M. (author), Picken, S.J. (author), Caro, J. (author)Thermal tuning of the transmission of an elastomer infilled photonic crystal cavity is studied. An elastomer has a thermal expansion-induced negative thermo-optic coefficient that leads to a strong decrease of the refractive index upon heating. This property makes elastomer highly suitable for thermal tuning of the transmission of a cavity,...conference paper 2011
